What's the difference between stainless steel hot rolling and cold rolling?
Cold rolling: it is rolled and rolled on the basis of hot rolled stainless steel plate and coil. Generally speaking, it is the process of hot rolling, pickling and cold rolling. Although the rolling process also causes the steel plate to heat up during the process, it is called cold rolling. Because of the cold rolling of continuous hot rolling, the mechanical properties are poor and the hardness is too high. It must be annealed to restore its mechanical properties. Rolled rolls are generally used to make products without bending or stretching.
The difference between hot rolling and cold rolling of stainless steel is that cold rolling is rolled on the basis of hot rolling.
1. cold-rolled steel plate due to a certain degree of hardening, low toughness, the price is more expensive;2. surface anaerobic cold rolling scale, good quality;3. cold deformation products, high dimensional accuracy, good surface quality;4. cold rolling because of its production process in all walks of life in a wide range of applications, such as various types of cold stamping parts, cold rolled cold extrusion profiles, cold coil spring, cold drawn wire, cold heading bolts.Hot rolling (hot rolling): relative to cold rolling, cold rolling is performed under recrystallization temperature, while hot rolling is rolling above recrystallization temperature.
