 42CrMo seamless steel pipes

42CrMo steel pipe is an ultra-high-strength steel with high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after quenching and tempering treatment, and good low-temperature impact toughness. 42CrMo seamless steel pipe is suitable for manufacturing large and medium-sized plastic molds that require certain strength and toughness.
The main uses of 42crmo seamless steel pipe are: used to manufacture forgings with higher steel strength and larger quenched and tempered cross-sections, such as large gears for locomotive traction, supercharger transmission gears, pressure vessel gears, rear axles, and connections under heavy loads. Rods and spring clips can also be used for deep oil well drill pipe joints and fishing tools below 2000m, and can be used for bending machine molds, etc.
42CrMo thick-walled steel pipe is an ultra-high-strength steel with high strength and toughness, good hardenability, no obvious temper brittleness, small deformation during quenching, and high fatigue limit and multiple impact resistance after quenching and tempering. Ability, good low-temperature impact toughness, high creep strength and durable strength at high temperatures. This steel is usually tempered and then surface quenched as a heat treatment solution.

42CrMo thick-walled steel pipe manufacturing process
1. Hot rolling (extruded seamless steel pipe): round tube blank → heating → perforation → three-roll cross rolling, continuous rolling or extrusion → detubing → sizing (or diameter reduction) → cooling → straightening → hydraulic test (or flaw detection) → Mark → Warehouse
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 tube → heat treatment → straightening →Hydraulic test (flaw detection)→Marking→Storage

42CrMo thick-walled steel pipes are mainly used in water supply projects, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, and urban construction. For liquid transportation: water supply and drainage. For gas transportation: coal gas, steam, liquefied petroleum gas. For structural purposes: piling pipes, bridges; pipes for docks, roads, building structures, etc.
