Stainless Steel Plate

Hot rolling of stainless steel: It uses slab (mainly continuous casting slab) as raw material, and after heating, it is made into strip steel by rough rolling unit and finishing rolling unit. The hot steel strip coming out of the last rolling mill of finishing rolling is cooled to the set temperature by laminar flow, and rolled into steel strip coil by coiler. The cooled steel strip coil is processed into steel plate, flat coil and longitudinally cut steel strip products through different finishing lines (flattening, straightening, cross cutting or longitudinal cutting, inspection, weighing, packaging and marking, etc.) according to different needs of users.
Cold rolling of stainless steel: It is processed and rolled on the basis of hot-rolled stainless steel plate coil. Generally speaking, it is a process of hot rolling → pickling → cold rolling. Although the steel plate will heat up due to rolling during the processing process, it is still called cold rolling. Because the cold rolling is formed by continuous cold deformation of hot rolling, the mechanical properties are relatively poor and the hardness is too high. It must be annealed to restore its mechanical properties. The one without annealing is called hard rolled coil. Hard rolled coil is generally used for products that do not require bending or stretching.
