0Cr13 is the one with the lowest CR content among martensitic stainless steels. It is stainless and corrosion resistant better than 1Cr13, 2Cr13, 3Cr13, 4Cr13 martensitic stainless steels with high carbon content. It has good plasticity, toughness and cold formability, and is superior to other martensitic stainless steels with higher CR content.

When the C content of 0Cr13 steel is very low, its plasticity, especially toughness, and cold formability will be significantly improved. 0Cr13 steel is mainly used in the manufacture of water vapor resistance, ammonium bicarbonate mother liquor, hot sulfur petroleum corrosion parts and equipment linings, etc. The corresponding U.S. grade of this steel grade is 405, and the specific gravity is, 0Cr13 is the lowest CR content among martensitic stainless steels.

20Cr13 belongs to the national standard martensitic stainless steel, and the implementation standard "GB T 1221-2007".

20Cr13 stainless steel has high hardness and good corrosion resistance in the quenched state. Many of them are used for cutting tools, which are "cutting edge" martensitic steels, and are also used for surgical tools, such as Brinell high-chromium steel, which is the earliest stainless steel, and is also used as steam turbine blades, etc., with a wide range of applications.

The chemical composition of 20Cr13 is shown below

The biggest difference between the two stainless steels is that the carbon content in the chemical composition is quite different: the carbon content of 2Cr13 stainless steel, the carbon content of 0Cr18Ni9 stainless steel, and the difference in carbon content causes their different characteristics:

2Cr13 stainless steel has high hardness, wear resistance and toughness after heat treatment, and its mechanical properties are among the best in stainless steel, but the disadvantage is that the corrosion resistance and weldability are poor. It is mostly used to make parts in complex situations, such as stamping dies.

0Cr18Ni9 is our most commonly used 304 stainless steel, which has good corrosion resistance, machinability and high temperature resistance, but the heat treatment effect is not large, and it is mostly used for the welding of corrosion-resistant equipment.

The characteristics of the above two stainless steels are quite different, and it is not recommended to replace each other.
