35CrMo7 Structural Steel Bar
35CrMo7 alloy structural steel has high long-lasting strength and creep strength at high temperature, low temperature impact toughness is good, the working temperature of high temperature up to 500 degrees, low temperature to -110 degrees, and has high static strength, impact toughness and High fatigue strength, good hardenability, no tendency of overheating, small deformation during quenching, good ductility during cold deformation, moderate machinability, but with temper embrittlement of the first type, poor weldability, preheating before welding To 150-400 degrees, post-weld heat treatment to eliminate stress, generally after quenching and tempering, but also in high surface quenching or quenching and low temperature tempering after use
35CrMo alloy steel applications:
Used in the manufacture of shock, bending, high load of a variety of machines in the important parts, such as rolling mill herringbone gears, crankshafts, hammer rod, fasteners, turbine engine spindles, axles, engine transmission parts, large Motor shaft, perforator in petroleum machinery, boiler bolts with operating temperature less than 400 degrees, nuts less than 510 degrees, high pressure seamless heavy wall pipes in chemical machinery (temperature 450-500 degrees, non-corrosive medium) , But also can be used instead of 40CRNi for manufacturing high load transmission shaft, turbine rotor, large section gear, supporting shaft (diameter less than 500mm), etc.
