Introduction

20CrMo steel is a low-alloy high-strength steel with good hardenability and heat resistance. After appropriate heat treatment, it can exhibit high strength and hardness while maintaining good toughness and plasticity. These characteristics make it an ideal choice for manufacturing precise steel pipes. 20CrMo seamless steel pipe is made through cold drawn process. Cold drawn process is suitable for producing small diameter and high precise seamless steel pipes.

 

Features of 20CrMo seamless alloy steel pipes

1. High strength and good toughness: 20CrMo seamless alloy steel pipes have high tensile strength and can withstand large mechanical loads. They also have good toughness and are less prone to brittle fracture.

2. High dimension precision and smooth surface: 20CrMo seamless alloy steel pipe is made through cold drawn process, with a smooth surface. Its tolerance on dimension is smaller than ordinary seamless steel pipes.

3. Good corrosion resistance: After heat treatment, 20CrMo seamless alloy steel pipes have good oxidation resistance, extending the service life of steel pipes.
