Cold rolled: Hot rolled coil is used as raw material, and the oxide skin is removed by pickling. The product is rolled coil. The cold work hardening caused by continuous cold deformation makes the strength, hardness and toughness and plasticity of rolled coil increase, so the stamping performance will deteriorate and can only be used for parts with simple deformation. Rolled coil can be used as raw material for hot galvanizing plant because annealing lines are set up in hot galvanizing units. The weight of rolled coil is generally 6-13.5 tons. The hot rolled pickling coil is rolled continuously at room temperature. The inner diameter is 610 mm.
Cold Rolled Stainless Steel Sheet / Plate:
a. Stretch good, toughness, but the price is more expensive;
b. Cold rolling processing surface without oxide skin, good quality;
c. Cold rolling is generally used in the production of strip, the rolling speed is high;
d. Cold rolling than the thickness of the high precision. Mechanical properties, surface and so on in the hot rolling;
e. Cold-rolled steel coil due to a certain degree of work hardening, low toughness, but can achieve better yield ratio, used for cold-formed spring and other parts;
f. Cold coil yield point closer to the tensile strength, so the use of risk in the process of no predictability, when the load exceeds the allowable load prone to accidents
g. The surface of the cold rolled steel coil without plating is gray.
h. Cold rolled steel plate surface smoothness is higher than the hot rolled steel coil.
