SWRCH 10A Cold Heading Steel Bar
SWCH10A is a Japanese brand, is a high-quality carbon steel grades, the chemical composition: C 0.08 ~ 0.13%, Si ≤ 0.10%, Mn 0.30 ~ 0.60%, P ≤ 0.0330%, S ≤ 0.035, Al 0.02%. Equivalent to the Chinese brand No. 10 steel, the steel low carbon content, are low carbon steel, therefore, good plasticity, suitable for plastic deformation through the production of parts, such as: manufacturing thin plate for cold stamping parts, cold heading parts, Can also be carburizing, carbonitriding for the manufacture of friction plates, piston pins and so on.
