Corrosion-resistant roller chain is perfect for those applications where withstanding corrosion damage is key. Choosing the right kind of chain relies heavily on which application type and what kind of performance are needed. We stock stainless steel roller chain, coated roller chain, nickel-plated roller chain, and zinc-plated roller chain. All of these materials 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. These specialty chains are also ideal for high-humidity environments. All stainless steel, coated, nickel-plated, and zinc-plated roller chains come in standard ANSI sizes and can be custom-made to meet your specific needs.
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 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 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 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.
