Hot Rolled JIS G4105 Seamless Steel Pipe, namely 35CrMo Alloy Steel Pipe, has high static strength, impact toughness and high fatigue limit, higher hardenability than 40Cr, high creep strength and lasting strength at high temperature, long-term working temperature Up to 500℃; G4105 Seamless Steel Pipe has medium plasticity and poor weldability during cold deformation. Low temperature to -110 degrees Celsius, and has high static strength, impact toughness and high fatigue strength, good hardenability, no overheating tendency, small quenching deformation, acceptable plasticity during cold deformation, medium machinability, but some The first type of tempering brittleness is not good in weldability. G4105 Seamless Steel Pipes needs to be preheated to 150~400 degrees Celsius before welding, and post-weld heat treatment to eliminate stress. Generally, it is used after quenching and tempering treatment. Use after tempering at medium temperature. G4105 Alloy Steel Pipe is used to manufacture important parts in various machines subject to shock, bending and torsion, high load, steam turbine engine main shaft, axle, engine transmission parts, large motor shaft, perforator in petroleum machinery, the working temperature is lower than 400 degrees Celsius boiler bolts, nuts below 510 degrees Celsius, high-pressure seamless thick-walled conduits in chemical machinery (temperature 450~500 degrees Celsius, non-corrosive medium), etc.; G4105 Alloy Steel Tube can also be used instead of 40CrNi to manufacture high Load transmission shaft, turbine engine rotor, large section gear, support shaft (diameter less than 500MM), etc.; process equipment materials, pipes, welding materials, etc.
