Corrosion Resistant Roller Chains Stainless Steel Roller Chains General Information Hitachi Stainless Steel roller chains are available in a variety of grades to meet the speci c requirements of each application. The following are the standard types of stainless steel products available from Hitachi: 304SS: All components are made from 304 series austenitic stainless steels (18-8, ASME 304 Series or better), and have excellent corrosion resistance and good mechanical properties over a wide range of temperatures. Because 304 series stainless is not heat treated, the ultimate strengths and rated working loads are lower than carbon steel, nickel plated, and Perfect Coat PlusTM roller chains. 316SS: These chains are produced from a combination of AISI 316 and a copper enriched modi ed 316 stainless alloy for superior resistance to stress corrosion cracking and pitting. This series also offers excellent temperature resistance. Strength and rated working loads are equivalent to 300SS. 600SS: Pins are produced from precipitation hardened 600 series stainless steel for an excellent combination of corrosion resistance and wear performance. Bushings and rollers are 304SS with a unique surface treatment that improves wear resistance. The link plates are made from 304 series austenitic stainless steels. Resistance to corrosion of 600SS is slightly reduced compared with the 304SS Series however the working load values are increased by approximately 34%. 6000SS: Superior wear resistance is obtained by through a proprietary surface treatment of the pins and rollers. The corrosion and wear resistance are superior to 600 Series stainless steel in a majority of applications. We do note however the wear resistance bene ts of this series are reduced with increasing temperature and 600 series is recommended at temperatures above 300 degrees F. Mega Chain: A unique design con guration gives this product nearly the same strength as carbon steel chains with corrosion resistance equal to 304SS. In addition a greater pin/bushing bearing area yields higher working loads and a unique labyrinth seal design protects the internal components from abrasion due to foreign materials.
