Cold-rolled stainless steel refers to cold-rolled steel plates, which are steel plates produced by cold rolling.
Cold rolling is to further thin the No. 1 steel plate to a target thickness under room temperature conditions. Compared with hot-rolled steel plates, cold-rolled steel plates have a more precise thickness, smooth and beautiful surface, and have various superior mechanical properties, especially in terms of processing performance. Because cold-rolled raw coils are relatively brittle and hard and not suitable for processing, cold-rolled steel plates are usually required to be annealed, pickled and surface smooth before being handed over to customers. The maximum thickness of cold rolling is 0.1--8.0MM or less. For example, the thickness of cold-rolled steel plates in most factories is less than 4.5MM. The minimum thickness and width are determined according to the equipment capabilities and market demand of each factory.
Stainless steel cold-rolled steel plates are stainless steel plates produced by the cold rolling process. Those with a thickness of no more than 3mm are thin plates, and those with a thickness greater than 3mm are thick plates. It is used to make corrosion-resistant parts, pipelines, containers, medical equipment, ship equipment, etc. in petroleum and chemical industries. Its classification and grades are as follows:
1. Austenitic steel
In addition to the same as the hot rolled part (29 types), there are also: (1) 2Cr13Mn9Ni4 (2) 1Cr17Ni7 (3) 1Cr17Ni8
2. Austenitic-ferritic steel
In addition to the same as the hot rolled part (2 types), there are also: (1) 1Cr18Ni11Si4AlTi (2) 1Cr21Ni5Ti
3． ferritic steel
In addition to the same as the hot rolled part (9 types), there are also: 00Cr17
4． martensitic steel
In addition to the same as the hot rolled part (8 types), there are also 1Cr17Ni2
5. Precipitation hardened steel: same as hot rolled part
