S20C

S20C is a Japanese standard carbon structural steel with slightly higher strength than No. 15 steel. It rarely needs quenching and is not susceptible to temper brittleness. It has high cold deformation plasticity and is generally suitable for bending, rolling, flanging, and hammering. It has good weldability for arc welding and contact welding.
