201 stainless steel is mainly used for decorative pipes, industrial pipes, and some shallow stretching products. 201 stainless steel with unstable Ni-Cr alloy has the ability to withstand general corrosion like 304. 201 stainless steel is mainly used in high-temperature applications, which require a strong anti-sensitization performance to prevent the intergranular corrosion at a lower temperature.
The nickle content of 201 stainless steel omega replica watches
in the market is from 0.5 to 5, and there are large differences between compositions according to downstream use requirements. 201 stainless steel is mainly used to replace 304 stainless steel in some specific uses. Due to manganese element, the color of 201 stainless steel will be darker than that of 304, which is much brighter and whiter, but this is not easy to distinguish via the naked eye. Because the nickel content is different, the corrosion resistance of 201 is not better than that of 304, and the higher carbon content makes 201 stainless steel harder and more brittle compared to 304. 201 contains manganese, which can rust for long period in moist and salty air.
201 stainless steel products include 201 stainless steel pipes (including square pipes and round pipes), 201 stainless steel plates, 201 stainless steel rods, 201 stainless steel coils, 201 stainless steel strips and 201 stainless steel wires.
Price Quotes
The price of 201 stainless steel is related to its thickness, brand, region and other factors. Different specifications are largely different in the price, for example, the general specifications of 201 stainless steel material is sold at 8300 yuan/ton, while the price of special precise thin material may be as high as 27000-31000 yuan/ton.
Density Components
The actual density of 201 stainless steel is about 7.73, but generally calculated according to 7.93. Compared to 304 stainless steel, it is relatively light. The chemical composition of 201 Stainless Steel in GB/T 20878-2007 (C) is as follows:
Carbon: ≤0.15 Silicon: ≤0.75r Manganese: 5.5～7.50 Chromium: 16.0~18.0 Nitrogen: ≤0.25 Phosphorus: ≤0.060 Sulfur: ≤0.030 Nickel: 3.50-5.5% Copper: Half copper 0.8% high copper 1.5%
Material Description
The national standard brand of 201 Stainless Steel is 1Cr17Mn6Ni5N, and the domestic main 200 series include J1, J3, J4, 201 and 202, and later, there appeared 200 with lower the nickel content. The main characteristic of 200 series stainless steel is containing manganese, breitling replica watches
which is why we usually call it chromium manganese stainless steel. Most 200 series stainless steels sold in the Chinese market fail to control sulphur content and carbon content in accordance with GB, instead, they substitute manganese (and nitrogen) for some or all nickel to produce austenitic stainless steel with lower nickel content.
