EN10083-3 Seamless Precision Steel Tube 42CrMo4 QT Cold Drawn Extruded Steel Pipe

EN10083-3 42CrMo4+QT Cold drawing Alloy precision steel tube

42CrMo4 Carbon Steel Seamless Tubes are most commonly used for general purpose applications worldwide.

42CrMo4 is an alloy structural steel with high strength, high hardenability, good toughness, small deformation during quenching, and high creep strength and endurance strength at high temperatures. 42CrMo4 steel is a modified AISI 4140 steel, mainly used in the manufacturing of seamless hydraulic cylinders or gas cylinders, heavy machinery, cranes, excavators and forklifts, etc.
