Product Description

20CrMo is an alloy structural steel with high hardenability and no temper brittleness. However, its weldability is poor, similar to 45#, and it has a certain tendency to cold crack. However, 20CrMo has good cutting processability and cold strain plasticity.

Normally, 20CrMo is used in the tempered or carburized and quenched state, and can be used as a substitute for 20CrMnTi, 20Cr, 20MV, 20Mn2, 20CrNi and other materials. It is suitable for manufacturing high-pressure pipelines and various fasteners working in non-corrosive media with operating temperatures below 250°C and nitrogen-containing hydrogen mixture media. In addition, it is also suitable for manufacturing higher-grade carburized parts, such as gears, shafts, etc.


20CrMo is widely used in aerospace, electric power, petrochemical, shipbuilding, machinery, electronics, environmental protection and other industries. In these industries, the excellent properties of 20CrMo make it an ideal material choice.

In the field of pipelines, 20CrMo is widely used in pipeline systems that transport various fluids. It can be used in pipelines transporting oil, natural gas, coal gas, water and certain solid materials. Due to its economical cross-section, 20CrMo is an ideal material for manufacturing structural parts and mechanical parts. For example, it is often used in the manufacture of oil drill pipes, automobile drive shafts, bicycle frames, steel scaffolding for construction, etc.

In addition, 20CrMo can also be used to manufacture ring-shaped parts to improve material utilization, simplify manufacturing processes, and save materials and processing hours. For example, rolling bearing rings, jack sets and other annular parts have been widely manufactured using 20CrMo steel pipes.

In short, the application fields of 20CrMo are very wide, covering the different needs of multiple industries. Its excellent performance and economy make it one of the indispensable materials in the engineering field.
