42CrMo4 alloy forged bar has super performance. It can get different hardness through different heat treatment methods, and can meet many kinds of mechanical processing needs. It is widely applied.
42CrMo4 alloy steel is used to manufacture forgings with higher strength and conditioning section large, such as locomotive traction gears, with supercharger drive gear, the rear axle, the connecting rod and the spring load greatly clip, 42CrMo4 steel can also be used for the deep oil drill pipe joints and fishing tools etc. 42CrMo4 alloy forged bar is especially prestigious in the mould industry.
