Carbon Steel AISI 1137 is a general purpose alloy, used for parts that require strength and machinability. It demonstrates good stress resistance, is considered re-sulphurized, and has a machining cost factor of 2.7 in comparison to AISI 12L14. Welding is not ideal due to high sulfur content. 1137 can be annealed, quenched, tempered, and heat treated.
