U.S. Tsubaki Power Transmission LLC (ustsubaki.com) has come out with the Super Stainless Steel roller chain. This is a unique roller chain product that combines the corrosion resistance and extreme temperature operating range of Tsubaki’s AS series stainless steel chain with the strength of a carbon steel chain.
Before this R&D breakthrough, multiple stainless chains would be required to provide the equivalent strength of a similarly sized carbon steel chain. This would also require costly and time-consuming equipment redesigns in order to achieve comparable working loads. Super Stainless eliminates that need. As an example, one #50 Super Stainlesschain has a comparable maximum allowable load (MAL) to one #50-6AS (6-strand) roller chain.
