Tool and Die Steel S7 bars are air-hardening, shock-resistant steels primarily made up of carbon (0.45–0.55%), chromium (3.0–3.5%), molybdenum (1.3–1.8%), and vanadium (0.2–0.3%). This unique blend provides remarkable toughness, wear resistance, and impressive impact strength. After heat treatment, S7 achieves a hardness of 54–56 HRC and retains its strength even in extreme temperatures. With a tensile strength of around 1700 MPa and excellent dimensional stability, S7 steel is perfect for applications that demand resistance to shock loading and frequent thermal cycling.
