Carbon Structure Steel S20C

APPLICATIONS: S20C grade is a general purpose carbon steel suitable for surface hardening. It may, as required, be case hardened, welded and machined. Cold forming may be carried out, preferably from a spheroidized structure. This grade of steel is used for forged motor shafts, hydraulic shafts and pump shafts, as well as machinery parts. MACHINABILITY For parts with a diameter less than 2” (50mm) this grade has been found on occasion to show best machinability when normalized. Parts over 2” (50mm) diameter might be machined following forging or rolling. WELDABILITY This grade of steel may be welded by all normal methods: low-carbon electrodes are recommended. Low-hydrogen electrodes are recommended together with preheat at 300 – 500 º F (150 – 260 º C.) to be maintained during welding, Cool slowly and stress relieve where possible. Production: Round and Flat Size according to customer's requirement
