20CrMo Alloy Pipe

20CrMo Alloy Pipe
Details:
20CrMo is a chromium-molybdenum alloy steel, mainly used for manufacturing carburized gear steel. After carburizing and heat treatment, its strength is significantly enhanced, while maintaining good toughness and wear resistance, making it an ideal choice for manufacturing critical components such as turbine blades and boiler partitions.

20CrMo is a chromium-molybdenum alloy steel, mainly used for manufacturing carburized gear steel. After carburizing and heat treatment, its strength is significantly enhanced, while maintaining good toughness and wear resistance, making it an ideal choice for manufacturing critical components such as turbine blades and boiler partitions.

20CrMo alloy steel pipe is a type of steel pipe made from 20CrMo alloy steel, featuring high strength and hardness. It is widely used in the manufacturing of high-strength, high-hardness and wear-resistant parts, such as bearings, gears, transmission shafts, connecting rods and other mechanical parts, as well as in engineering structures that bear high loads and impact loads, such as in the automotive, marine, bridge and construction industries.

 

Manufacturing Process

 

1. Hot rolling (extruded seamless steel pipe): round tube billet → heating → perforation → three-roll skew rolling, continuous rolling or extrusion → Stripping → sizing (or reducing) → cooling → straightening → hydraulic test (or detection) → marking → storage

2. Cold-drawn (rolled) seamless steel pipe: round tube blank → heating → perforation → heading → annealing → pickling → oiling (copper plating) → multi-pass cold drawing (cold rolling) → billet → Heat treatment → straightening → hydraulic test (inspection) → marking → storage
