201 Stainless Steel Coil

201 stainless steel has a certain acid, alkali resistance, high density, polishing, no bubbles, no pinhole and other features, is the production of various watchcase, strap, cover, high-quality materials. Mainly used for decorative pipes, industrial pipes, and some shallow stretch products.

China mainly has the following 200 kinds of steel grades: J1, J3, J4,201,202. Later appeared to lower nickel content of the 200 steels, as 201C, is in the late Chinese individual steel developed 201 extension steel, 201 of the national standard is: 1Cr17Mn6Ni5N, 201C continue to reduce the nickel content in 201 on the basis of the increase of manganese content.

Product introduction

Chemical composition

Mechanical property

Application

1)201 stainless steel is widely used in All kinds of watchband, watchband bottom cover, high quality materials etc.

2)201 stainless steel is also Widely used in the production original material of Decorative tubes, industrial tubes, and some of the products.

3)201 can also be applied to high temperature materials. Because high temperature applications require relatively strong resistance to the material to prevent intergranular corrosion at low temperatures.

4)Because the surface of the 201 materials can be a variety of surface processing, so 201 material is also widely used in the decoration industry filed.

Small knowledge

200 series stainless steel is in the period of World War II, as the 300 series stainless steel substitutes in the United States first developed successfully. At that time, as a result of the war, as a strategic material nickel is strictly controlled by the relevant countries, the United States nickel supply is seriously insufficient. In order to solve the serious shortage in the supply of nickel under the production and supply of stainless steel, the United States has developed a generation of nickel with manganese austenitic stainless steel of the new steel series.
