ASTM S235 Cold Rolled Steel Sheet

ASTM S235 Cold Rolled Steel Sheet-Cold rolling: hot rolled steel coils are used as raw materials, and after the oxide skin is removed by pickling, cold rolling is carried out. The finished product is rolled hardened coils. As the cold work hardening caused by continuous cold deformation increases the strength and hardness of the rolled hardened coils, and the toughness and plastic index decreases, the stamping performance will deteriorate, and it can only be used for parts with simple deformation. The rolled hard coil can be used as the raw material of the hot galvanizing plant, because the hot galvanizing units are equipped with annealing lines. The weight of the hardened coil is generally 6~13.5 tons. The hot rolled pickled coil is continuously rolled at room temperature. The inner diameter is 610mm.
Product features: because it has not been annealed, its hardness is very high (HRB is greater than 90), and its mechanical processing performance is very poor, so it can only perform simple directional bending processing (perpendicular to the coiling direction) that is less than 90 degrees
