Cold rolled stainless steel sheet

Product introduction and parameters

Cold-rolled stainless steel plate is a cold-rolled stainless steel plate, which is further thinned at room temperature to the target thickness of the hot-rolled stainless steel plate. Compared with the hot-rolled steel plate, the thickness of cold-rolled stainless steel plate is more accurate, the surface is smooth and beautiful, and it also has a variety of superior mechanical properties, especially in terms of processing properties.
Because the cold-rolled raw roll is brittle and hard, it is not suitable for processing, so the cold-rolled stainless steel plate is usually required to be annealed, pickling and surface smoothing before being handed to the customer.
There are many kinds of cold-rolled stainless steel plate grades, common 201, 303, 304, 304L, 321, 316, 316L, 309S, 310S, 2520, 904, 904L duplex steel series S32205 S32507 and so on.

Material introduction

Stainless steel is a kind of stainless steel with stainless steel and corrosion resistance as the main characteristics, and the chromium content is at least 10.5%, and the carbon content is not more than 1.2%. Stainless steel not only has good corrosion resistance, but also has the advantages of high strength, beauty, hygiene and environmental protection. According to the different chemical composition and use, stainless steel can be divided into ferritic type, martensitic type, austenite-ferritic type, precipitation hardening type and other different types. In the field of application, stainless steel is widely used in various fields, such as construction, machinery, electronics, chemical industry and so on. Stainless steel manufacturing and processing also need to go through a number of steps and processes, including smelting, casting, heat treatment, etc. The surface treatment of stainless steel is also very important, and its aesthetics and corrosion resistance can be enhanced by polishing, sandblasting, coloring, etc. In short, stainless steel is a kind of metal material with various advantages and characteristics, which is widely used in various fields, and its manufacturing and processing also need to go through multiple steps and processes.

The advantages of stainless steel are:

Corrosion resistance: Stainless steel is mainly composed of chromium, nickel and other elements, these elements can form a dense oxide film, can prevent further oxidation of metal ions on the steel surface, protect the steel surface from chemical corrosion and electrochemical corrosion.

High strength: stainless steel has high strength, good mechanical properties, high tensile strength, high hardness, good fatigue resistance, etc. At the same time, the ductility and impact toughness of stainless steel are very good, and can meet various processing requirements.

Beautiful: Stainless steel surface is smooth, easy to clean, and there are a variety of surface options, such as mirror, frosted, brushed, etc., very beautiful.
