18CrNiMo7-6

18CrNiMo7-6 is a low carbon steel with specific chemical composition and mechanical properties. This type of steel is widely used in engineering and industrial applications where a combination of high strength, toughness and wear resistance is required.The steel contains a relatively low carbon content (C: 0.15-0.21% carbon) which allows it to maintain weldability and toughness. The addition of chromium (Cr: 1.50 - 1.50%) improves the steel's hardenability and corrosion resistance and nickel Ni: (1.4 - 1.70%) contributes to the steel's toughness, impact strength and fatigue strength. Molybdenum (Mo: 0.25 - 0.35 %) improves the steel's strength and stability at high temperatures.18CrNiMo7-6 steel typically has a tensile strength in the range of 980 MPa to 1300 MPa, making it relatively strong.After appropriate heat treatment, 18CrNiMo7-6 steel can achieve high surface hardness, suitable for wear-resistant applications.This steel is known for its good impact toughness, which is important for resisting sudden loads or shocks.18CrNiMo7-6 steel often undergoes heat treatment processes such as quenching and tempering to achieve the desired combination of hardness and toughness.18CrNiMo7-6 steel is widely used in the manufacture of heavy gears, shafts, crankshafts and other components in machinery and automotive applications.The steel is often found in industries where high strength, good wear resistance and reliable performance under heavy loads are critical requirements.
