Cold Rolled Stainless Steel
Cold-rolled stainless steel means cold-rolled steel, which is a steel plate produced through cold rolling.
Cold rolling is the further reduction of a No. 1 steel sheet to a desired thickness at room temperature. Compared with hot-rolled steel sheets, the thickness of cold-rolled steel sheets is more accurate, and the surface is smooth and beautiful. At the same time, it also has a variety of superior mechanical properties, especially in terms of processing performance. Because the cold-rolled raw coils are relatively rigid and not suitable for processing, cold-rolled steel sheets are generally required to be passed to the customer after annealing, pickling, and surface smoothing. The maximum cold-rolled thickness is 0.1--8.0 mm or less. For example, the thickness of most cold-rolled steel sheets is less than 4.5 mm. The minimum thickness and width are determined according to the plant's equipment capacity and market demand.
The cold rolled stainless steel plate is a stainless steel plate produced by a cold rolling process. A plate with a thickness of not more than 3 mm is a thin plate, and a plate with a thickness of more than 3 mm is a thick plate. For the production of corrosion-resistant parts, petroleum, chemical pipelines, containers, medical equipment, ship equipment, etc., their classification and brand are as follows:
1. Austenitic steel
In addition to the same hot-rolled part (29 types), there are other types, such as 2Cr13Mn9Ni4, 1Cr17Ni7 and 1Cr17Ni8.
2. Austenite - ferritic steel
In addition to the same as the hot-rolled part (2 types), there are other types, such as 1Cr18Ni11Si4AlTi and 1Cr21Ni5Ti.
3. Ferritic steel
In addition to the same hot-rolled part (9 types), there are other types, such as 00Cr17.
4. Martensitic steel
In addition to the same hot-rolled section (8 types), there are other types, such as 1Cr17Ni2.
5. Precipitation hardening steel: with the hot rolling part.
