4130 4140 42CrMo4 4340 Forged Seamless Steel sleeve

42CrMo4 is an industrial material, belonging to the European standard high-strength alloy structural steel, 42CrMo4 is used to manufacture Forgings that require higher strength and larger tempering cross-section than 35CrMo steel, such as large gears for locomotive traction. So it's harder with this material.
