 42CrMo performance: after quenching after cold deformation of the plastic medium, high strength and toughness at high temperatures lasting high strength and creep strength, and strength and harden ability than 35CrMo steel, and higher fatigue strength and strong resistance to several attacks on the ability ofApplication: used as a strength for better fastener

  30CrMo Performance: After quenching after heat treatment, cold deformation of the plastic medium under 500Degrees Celsius with good high temperature strength, high hardenability, machinability is still good     Application: used as a medium machine bolt, stud, 500 Degrees Celsius the following high-pressure flange, nut and so on.
