Comparing Anti-rust Chains : Find Out the Most Suitable Application

Standard Carbon steel chains have good strength and wear performance, but they are not suitable for applications in corrosive environments. Stainless steel chains have excellent corrosion resistance, but the strength and wear resistance often cannot meet some customers’ needs.

MCC offers numbers of corrosion resistant coated chains with outstanding performance to meet your various applications, including CRF, mechanical zinc plated, nickel plated as well as galvanization and nickel plated.


CRF Coated Chain

MCC CRF coated chain delivers excellent protection in corrosive environments, and is able to withstand high and low temperatures for an extended period of time. In addition, the surface treatment is completely chromium-free and complying with legislation of RoHS, ELV and REACH regulations. 

CRF coating chain is more cost-effective than stainless steel and allow the carbon steel chains to have longer working life in corrosive environment; therefore it is an ideal option for aggressive environment.

GN (Galvanization and Nickel Plated Roller Chain)

Galvanization and nickel (GN) coated chain is our newly corrosion resistant chains which uses the new technology to electroplate the galvanization and nickel on carbon steel as protective coating. The characteristic properties of GN make it a suitable coating metal for numerous applications.

The chain with this surface treatment not only has attractive appearance which is similar to the stainless steel chain but has the same tensile strength as standard steel roller chain.

MZP (Mechanical Zinc Plated Roller Chain)

Electrolytic zinc plating is a common corrosion coating and it is widely used in light corrosive environment. However, Electrolytic zinc plating contains hexavalent chromium and is harmful to environment. Hydrogen embrittlement may also happen during the electrolytic zinc plated process. 

Whereas, our mechanical zinc plated is processed through peening the zinc powder mechanically onto the chain component surface. The process is done without the concern of hydrogen embrittlement.

MZP chain also provides the same tensile strength as standard steel roller chain.

NP (Nickel Plated Roller Chain)

Nickel plating is one of the most widely used anti-corrosive coatings. With a good corrosion resistance, nickel plated chain is ideal for humid environment and mildly corrosive applications requiring same tensile strength as standard steel roller chain.
