Applications
SCM415 steel is a alloy structural steel. It is used for engineering structural, like high tensile shafts, bolts and nuts, gears, pinions and spindles. Locomotive traction with the big gear, supercharger drive gear, pressure vessel, rear axle, gear load of connecting rod and a spring clip,SCM415 can also be used to under 2000 m deep well of oil drill pipe joint and the fishing Alloy, and can be used for bending machine mould, etc
