Bobina de acero inoxidable AISI201

201 Stainless Steel Coil

Introduction：

Mainly used for decorative pipes, industrial pipes, some shallow stretching products. 201 stainless steel plate has similar resistance to general corrosion with unstable nickel-chromium alloy 304. Long time heating of 201 stainless steel sheet in the temperature range of chromium carbide degree may affect alloy 321 stainless steel sheet and 347 in bad corrosive medium. 201 stainless steel sheet is mainly used for high temperature applications, high temperature applications require strong sensitization resistance of materials to prevent intergranular corrosion at lower temperatures.201 stainless steel, with certain acid resistance and alkali resistance, high density, no bubbles and no pinholes in polishing, is a high-quality material for the production of various watch cases and strap bottom covers. It is mainly used to make decorative tubes, industrial tubes, and some shallow stretch products.

species: 

China mainly has the following 200 series steel grades: J1, J3, J4, 201, 202. Later, there were 200 other steel grades with lower nickel content control. As for 201C, it is the extended steel grade of 201 developed by individual steel mills in China in the later period. The national standard grades of 201 are: old grade 1Cr17Mn6Ni5N, new grade: 12Cr17Mn6Ni5N 201C continues to reduce the nickel content and increase the manganese content on the basis of 201.

use：

It is applied to field open-air machines in chemical, coal and petroleum industries with high grain boundary corrosion resistance, heat-resistant parts of building materials and parts with difficulty in heat treatment.
