1Cr14Mn10Ni1 is an austenitic stainless steel.

1Cr14Mn10Ni1 Meaning: Chromium Cr content 14%, manganese Mn content 10%, nickel Ni content 1%, austenitic stainless steel, refers to stainless steel with austenitic structure at room temperature. When the steel contains about 18% Cr, 8% Ni 25%, and about C, it has a stable austenite structure.

Austenitic chromium-nickel stainless steels include the well-known 18Cr-8Ni steel and the high Cr-Ni series steel developed by adding Cr and Ni content and adding elements such as Mo, Cu, Si, Nb, and Ti.

In addition to being resistant to corrosion by oxidizing acid media, this type of steel can also resist the corrosion of sulfuric acid, phosphoric acid, formic acid, acetic acid, urea, etc., if it contains elements such as MO and CU. If the carbon content of this type of steel is lower than or contains Ti and Ni, its resistance to intergranular corrosion can be significantly improved. The high-silicon austenitic orange blind stainless steel has good corrosion resistance to concentrated nitric acid.

Due to its comprehensive and good comprehensive properties, austenitic stainless steel has been widely used in all walks of life.

1Cr18Ni9 is a stainless steel material.

1Cr18Ni9 is the basic type of 18-8 type stainless steel, and its carbon content is around the same. Changing the chemical composition on its basis can obtain steel grades with different properties. In order to maintain stable passivation in oxidizing acid, the chromium content of stainless steel should reach about 18%, and when the chromium content is 18%, in order to obtain austenitic structure at room temperature, 8%-9% nickel needs to be added to the steel grade, which is 18-8 type stainless steel.

Classification of stainless steel.

Stainless steel can be divided into four categories, namely stainless steel, acid-resistant stainless steel, heat-resistant stainless steel, and low-temperature stainless steel.

1. Stainless steel, which refers to the corrosion-resistant steel in the atmosphere and weak corrosive media.

2. Acid-resistant stainless steel, which refers to the steel that can resist corrosion in various strong corrosive media.

3. Heat-resistant stainless steel refers to stainless steel with high oxidation resistance and high enough high temperature strength at high temperature.

4. Low-temperature stainless steel is an alloy steel suitable for applications below 0 degrees, and it is called ultra-low temperature steel that can be used below minus 196 degrees Celsius.
