is a steel sheet obtained by further thinning the No. 1 steel sheet to a target thickness under room temperature conditions. Compared with hot-rolled steel, cold
rolled steel has a more precise thickness, smooth and beautiful surface, and also has various superior mechanical properties, especially in terms of processability. Because cold-rolled raw coils are relatively brittle and hard, and are not suitable for processing, cold-rolled steel sheets are usually required to be annealed, pickled and surface smoothed before being delivered to customers. The maximum thickness of cold rolling is below 0.1 -8.0MM. For example, the thickness of cold rolled steel plate in most factories is below 4.5MM; the minimum thickness and width are determined according to the equipment capacity and market demand of each factory.
is a stainless steel plate produced by cold-rolling process, the thickness is not more than 3mm is thin plate, and the thickness is more than 3mm is thick plate. It is used to make corrosion-resistant parts, petroleum and chemical pipelines, containers, medical equipment, marine equipment, etc. The classification and grades are as follows:1. Austenitic steelIn addition to the same as the hot rolled part (29 kinds), there are: (1) 2Cr13Mn9Ni4 (2) 1Cr17Ni7 (3) 1Cr17Ni82. Austenitic-ferritic steelIn addition to the same as the hot rolled part (2 types), there are: (1) 1Cr18Ni11Si4AlTi (2) 1Cr21Ni5Ti3. Ferritic steelIn addition to the same as the hot rolled part (9 types), there are: 00Cr174. martensitic steelIn addition to the same as the hot rolled part (8 kinds), there are 1Cr17Ni2
