Introduction to Corrosion Resistant Roller Chain

Corrosion resistant roller chain is a kind of roller chain which is designed to easily withstand extreme weather conditions, including salt, high humidity, snow- and rain storms. All of these materials used in roller chains are designed to withstand the rigors of corrosion-prone environments and are rust-proof, making them perfect for food processing, pharmaceutical, marine, and other corrosive applications.

Types of Corrosion Resistant Roller Chain

Stainless Steel Roller Chain

Stainless Steel Roller Chain is primarily used in highly abrasive applications due to offering remarkable anti-corrosive properties in harsh environments where moisture and chemicals are prevalent. For example, our stainless steel roller chain is ideal for use in food processing plants because it is able to withstand frequent washdowns with caustic cleaners. Furthermore, because stainless steel is non-magnetic, our ANSI-size chain is also ideal for use in the medical industry where MRIs are common. A common disadvantage to using stainless steel chain is that in strength-demanding applications, it can wear out quicker due to stainless steel being a much softer material than carbon steel. However, we do offer a special series that is just as strong as its carbon steel equivalent, in an ANSI size. As a result, stainless steel roller chains are an excellent choice for applications where corrosion resistance is essential.

Coated Roller Chain

Coated Roller Chain is used in a wide variety of applications, from transportation to manufacturing. It offers a number of advantages over other types of chains, including strength, durability, and resistance to wear. However, it can be susceptible to rust and corrosion, especially in damp or wet environments. Coated roller chain is made from standard ANSI carbon steel components, which means that it retains the same strength and performance ratings as the uncoated chain. The coating helps to protect the chain from rust and corrosion, making it an ideal choice for applications where moisture is a concern. However, it should be noted that the coating can eventually wear away over time, so coated roller chain is not suitable for all applications. When choosing a roller chain for your application, be sure to consider the environment in which it will be used and the potential for exposure to moisture. Coated roller chain is not recommended for chemical applications.

Nickel-Plated Roller Chain

Nickel-Plated Roller Chain is one of the most popular types of chain used in a variety of industries today. As the name implies, these chains are coated with a thin layer of nickel, which helps to resist corrosion and wear. Nickel-plated roller chains are often used in applications that have light to medium corrosion, such as food processing or outdoor power equipment. They offer high strength and corrosion resistance at a relatively low cost, making them an ideal choice for many applications. When properly maintained, nickel-plated roller chain can provide years of reliable service.

Zinc-Plated Roller Chain

Zinc-Plated Roller Chain uses an electrolytic process that deposits a thin layer of zinc on the surface of the metal. The zinc not only protects the underlying metal from corrosion but also provides a sacrificial coating that sacrifices itself to protect the metal. Rolled steel chains are particularly susceptible to corrosion, so zinc plating is often used to extend their service life. In addition to providing protection against corrosion, zinc-plated roller chains can also operate in a wide range of temperatures, from -40 degrees Fahrenheit to 400 degrees Fahrenheit. As a result, they are well suited for use in a variety of specialty conveying applications that require durability and high strength.

Manufacturing Process of Corrosion Resistant Roller Chain

Raw Material Selection
The production of corrosion resistant roller chains begins with the careful selection of raw materials. High-quality steel is the primary material for roller chain manufacturing due to its strength, durability and wear resistance. The steel undergoes rigorous testing to ensure it meets the required standards for tensile strength and hardness. In addition, the raw material selection process also needs to consider factors such as corrosion resistance and the ability to withstand varying operating conditions.

Forming and Cutting
Once the raw materials are selected, they go through a forming and cutting process that shapes them into the required roller chain components. This involves precision cutting and forming techniques to manufacture inner and outer links, pins, rollers and bushings. Advanced machinery and tools are used to ensure component accuracy and consistency, which is critical to the proper operation of the roller chain.

Heat Treatment
After the parts are formed and cut, they go through a critical stage called heat treatment. The process involves controlled heating and cooling cycles of steel components to enhance their mechanical properties. Heat treatment helps increase the hardness, strength and wear resistance of the steel, ensuring that the roller chain can withstand the harsh conditions encountered during operation.

Assembly
Once the individual components have been heat treated, they can be assembled into a complete corrosion resistant roller chain. The assembly process requires precision and attention to detail to ensure each component fits together seamlessly. Pins are inserted into the inner link plate, and rollers and bushings are added to form the unique structure of the roller chain. Advanced mechanical and automated assembly processes are often used to maintain consistency and efficiency in the assembly stages.

Lubrication and Surface Treatment
After the corrosion resistant roller chain is assembled, it is lubricated and surface treated to further improve its performance and life. Lubrication is essential to reduce friction and wear between the moving parts of a roller chain and ensure smooth operation. Additionally, surface treatments such as plating or coatings can be applied to provide corrosion resistance and improve the aesthetic appearance of the roller chain.

Quality Control and Testing
Before corrosion resistant roller chains are ready for distribution, they undergo strict quality control and testing procedures to ensure they meet the required standards. This includes inspecting the dimensions, tolerances and surface finish of the roller chain, as well as conducting tests to evaluate its tensile strength, fatigue resistance and overall performance. Any non-conforming products are identified and corrected to maintain the high quality of the roller chain.

Q: What are the advantages of stainless steel roller chain?

A: Attractive appearance of glossy stainless steel.
Exceptional corrosion resistance. But in certain highly corrosive conditions, stress-corrosion cracking may occur.
Exceptional corrosion resistance and strength at high temperatures. These chains can operate in high temperatures, but the manufacturer should be contacted for applications above 400°C.
These chains may be used in extremely low temperatures, because low temperature brittleness does not occur.
There is slight magnetism, due to the cold working processes.
Due to the cold working processes, the surface of the chains may rust in some conditions.
The tensile strength of Stainless Steel chain is almost half that of RS Roller Chains.
The chain parts are not heat-treated (such as quenching and tempering). The tensile strength and hardness of these parts are lower than that of RS Roller Chains.
Because the surface hardness of the working parts (pins, bushings and rollers) is low, the wear resistance is also less than that of RS Roller Chains. Due to the lower thermal conductivity of stainless steel, the working parts retain more heat, which also lowers the allowable tension of Stainless Steel Roller Chains. The allowable tension of the chain is determined by the wear resistance.

Q: What is chain stretch of corrosion resistant roller chain?

A: Chain stretch is defined as the difference in length of a chain due to the reduction of the outside diameter of the chain pins and the increase in diameter of the chain’s bushing. These two dimensions increase the length of the chain under load. This length difference between the chain’s original length and its current length is considered stretch. It is important for a user of chain to keep this pin/bushing area of the chain clean and lubricated to enhance the chain’s performance. Chain stretch also can be defined as the loss of material on the chain’s pins and bushings due to these components rubbing against one another. Special care must be given to reduce or eliminate any outside material such as grit, dirt, contaminant that interferes with this key area of the chain.

Q: What grade stainless steel chains do you offer?

A: We offer three grades of stainless steel chain in the roller chain family. 304 Series (18-8), 600 series (PHSS – precipitated heat treated stainless steel and known as 17-7/17-7), and 316 Series are all stainless steel roller chains offered by Wolff. Each grade has strong features for use in the marketplace. These chains are available with and without attachments. In the engineering chain family, we can supply chains with 300 series, 400 series and 600 series stainless steel chains.

Q: Should corrosion resistant roller chain be used for lifting applications?

A: Corrosion resistant roller chain is designed for power transmission between two drive centers. It is not meant for lifting. Leaf chain – a series of heat treated pins and sideplates – is designed for lifting and counterweight applications. Typically Peer Leaf Chain is designed to be connected to fixed anchors or clevises. Special care should be used to exclude slip fit connecting links to these applications. Slip fit connecting links in leaf chain reduce the chains tensile strength and ultimately, the performance of the chain. Only BL series leaf chain is covered by the ASME standards.

Q: If my application is using carbon steel chain, can I switch to a stainless steel chain without any loss in tensile strength or wear life?

A: Carbon steel components are all heat treated. 304 series stainless steel chains are not heat treated, therefore the wear surfaces of the pins and bushings (known as the bearing area of the chain) are softer than their carbon steel counterparts. This softer surface will reduce in a lower tensile strength but more importantly, there will be less wear resistance on a 304 series chain versus its carbon steel counterpart. A simple switch from 50 riveted roller chain to 50 stainless steel roller chain will not result in equal wear resistance.

Q: How to reduce corrosion resistant chain stretching in application?

A: There are a number of ways to reduce stretch or elongation in a chain application. Some of the ways are listed below:
Improve the lubrication itself and the process of applying the lube to the chain ensuring the lube is penetrating the pin/bushing area.
Choose a chain that has a higher hardness of the chain’s bushings and pins.
Select a chain where tension is reduced in the bearing area (the pin/bushing area). Either reduce the tension on the chain or choose a chain with a larger pin diameter.
Increase the number of teeth on the sprocket that the chain engaged with.

Q: Can corrosion resistant roller chains be used in food processing applications?

A: Yes, corrosion-resistant roller chains are commonly used in food processing applications where hygiene and cleanliness are paramount. Stainless steel chains are often preferred due to their resistance to corrosion and ability to withstand frequent washdowns and exposure to food-grade cleaning agents.

Q: How to maintain stainless steel roller chain?

A: Regular inspection of stainless steel roller chain appearance and operation to ensure all components are intact. If damage or corrosion is found, it needs to be replaced promptly.
In addition, the tension and position of the stainless steel roller chain were measured to ensure that the pitch size met the set-up requirements. As needed, remove a ring and reconnect the stainless steel roller chain to adjust the tension.
The daily need to regularly check the chain and sprocket wear, because they wear may damage the performance of the machine. If the chain shows signs of wear, you may need to adjust the sprocket to improve transmission. If the chain wear elongation of more than 3%, should be a timely replacement chain, or easy to generate jumping teeth.
At the same time pay attention to sprocket wear, do not recommend the new chain with the old sprocket, this will accelerate the chain wear. When a pair of chains are installed, the coplanarity of the two sprockets is an important step in the maintenance of the stainless steel roller chain.
Regular lubrication is also a key component of stainless steel roller chain maintenance. At the end of the inspection, the stainless steel roller chain is thoroughly lubricated with light petroleum-based oils. Prevent metal accumulation of dust and moisture, avoid chain corrosion, to maintain the smooth operation of the chain.
