Compared with the Chinese brand: 42CrMo
Alloy steel pipes are mainly used for high-pressure and high-temperature pipelines and equipment such as power plants, nuclear power, high-pressure boilers, high-temperature superheaters and reheaters. They are made of high-quality carbon steel, alloy structural steel and stainless heat-resistant steel. , by hot rolling (extrusion, expansion) or cold rolling (drawing).
It is mainly used to manufacture high-quality carbon structural steel, alloy structural steel and stainless and heat-resistant seamless steel pipes for steam boiler pipes with high pressure and above.
The material of the alloy tube is roughly as follows:
16-50Mn, 27SiMn, 40Cr, 12-42CrMo, 16Mn, 12Cr1MoV, T91, 27SiMn, 30CrMo, 15CrMo, 20G, Cr9Mo, 10CrMo910, 15Mo3, 15CrMoV, 35CrMoV, 45CrMo, 15CrMoG, 12CrMoV, 45Cr, 50Cr, 45CrNiMo, etc.
