ASTM A240 Mirror Finish Cold Rolled Stainless Steel Coil 201 SS
201 stainless steel circulating on the market, nickel content is about 1 nickel, according to the requirements of
the composition of large differences. This type of steel is mainly used to replace 304 stainless steel in some specific
applications. 201 steel contains manganese and will rust in humid and salty air for a long time. Because of the
relationship between manganese element color will be darker than 304 steel, but the naked eye is more difficult
to distinguish. Due to the different nickel content, 201 stainless steel is less resistant to corrosion than 304. The
higher carbon content makes 201 stainless steel harder and more brittle than 304.

Cold Rolled Process:
Cold rolling: hot rolled steel coil is used as raw material for cold continuous rolling after acid pickling to remove oxide scale. The finished product is hard rolled coil. Due to the cold work hardening caused by continuous cold deformation, the strength and hardness of hard rolled coil increase and the toughness and plasticity index decrease. Therefore, the stamping performance will deteriorate and can only be used for simple deformed parts. The hard rolled coil can be used as the raw material of the hot-dip galvanizing plant, because the hot-dip galvanizing units are equipped with annealing lines. The weight of rolled hard coil is generally 6 ~ 13.5 tons. The hot-rolled pickling coil is continuously rolled at room temperature. The inner diameter is 610mm.
