Product Description
70MnMoCr8 1.2824 Alloy Steel Forged Tool Steel
1: 70MnMoCr8 Steel Introduction
70MnMoCr8 tool steel, a high-quality steel widely used in industrial manufacturing, plays an important role in mold making, cutting tools, and heavy-duty machine parts due to its excellent performance. The alloy composition of this steel is carefully blended to provide high strength, high hardness, and excellent wear resistance for long-lasting stability and durability in harsh operating environments. The strength characteristics of 70MnMoCr8 tool steel are particularly impressive, with extremely high levels of tensile strength, which means that it effectively resists the risk of deformation and fracture in working environments subjected to heavy loads and high stresses. In addition, the steel's hardness is considerable, reaching Rockwell hardnesses of over 60 after appropriate heat treatment, ensuring excellent performance in cutting and grinding processes.
