20Cr13 is a martensitic stainless steel with excellent wear resistance and corrosion resistance, commonly used in the manufacture of products such as cutting tools and bearings that require high hardness and wear resistance. Its mechanical and physical properties can vary depending on specific production processes and heat treatment conditions.

The advantages of 20Cr13 stainless steel mainly include high strength, good corrosion resistance, excellent mechanical properties, good processing performance, and heat treatment performance. ‌

20Cr13 stainless steel has high tensile strength and elongation strength, as well as excellent elongation and cross-sectional shrinkage, making it very suitable for manufacturing parts that can withstand high-intensity pressure loads, such as automotive engine blades, hot oil pumps, shafts and bushings, impellers, hydraulic press valves, etc. In addition, 20Cr13 stainless steel has a high chromium content, which can form a dense oxide film, effectively preventing corrosion from oxygen, water, and other media, and has good corrosion resistance. This type of stainless steel also has good heat treatment properties, and its structure and properties can be changed through heat treatment, such as annealing which can improve plasticity and toughness, and quenching which can improve hardness and strength.

The chemical composition of 20Cr13 stainless steel includes 0.16% to 0.25% carbon and 12.00% to 14.00% chromium, as well as relatively low content of other alloying elements. This composition gives it stable properties such as density, melting point, specific heat capacity, thermal conductivity, and linear expansion coefficient. In addition, 20Cr13 steel also has good wear resistance and corrosion resistance, making it suitable for manufacturing parts and tools that need to withstand impact and wear.

In summary, 20Cr13 stainless steel is widely used in the manufacturing of various industrial products, such as pressure vessels, chemical equipment, food processing equipment, etc., due to its excellent mechanical properties, corrosion resistance, processing performance, and heat treatment performance, and has become an indispensable material in the industrial field.
