Stainless Steel For Springs

Spring Material is specified in JIS G 4313 and is used for springs because it can obtain high strength through cold working and heat treatment. SUS301, SUS304, SUS631, SUS632J1, and SUS420J2 are the five common grades of stainless steel used in TOKKIN's spring manufacturing. Depending on the application and requested specifications, TOKKIN can assist you in selecting the correct material for you. TOKKIN provides stainless steel foil and other specifications (plate thickness and temper) that are not generally distributed, in optimal conditions, because we can produce to order from small lots.
