The difference between 42CrMo and 42CrMo4 steel pipesThe difference between 42CrMo and 42CrMo4 steel pipes
The function of 42CrMo4 steel pipes
42CrMo steel pipes are used to manufacture forgings with higher strength and larger quenched and tempered section, such as large gears for locomotive traction, supercharger transmission gears, rear axles, connecting rods, and spring clamps that are heavily loaded, and can also be used below 2000m Oil deep well drill pipe joints and oil equipment tools, and can be used for molds of bending machines, etc.
