Cold Rolled Hot Rolled Stainless Steel Strips 200 Series 300 Series 400 Series
Product Description
1. Stainless steel strip coil is rolled by cold rolling mill at room temperature. The conventional thickness is between 0.1mm and 3mm, and the width is between 100mm and 2000mm.
Cold rolled stainless steel strip has many advantages such as smooth and flat surface, high accuracy, good mechanical properties, and can be rolled or processed into coated steel plates. The sequence of the production process is pickling, normal temperature rolling, process lubrication, annealing, leveling, precision cutting, and packaging.
2. Hot rolled stainless steel strip is a strip with a thickness of 1.80mm to 6.00mm and a width of 50mm to 1200mm, which is produced by the hot rolling mill. Hot rolled stainless steel strip has many advantages such as low hardness, easy processing and good extensibility.
Its production process is pickling, high temperature rolling, process lubrication, annealing, smoothing, fine cutting, and packaging.
