When choosing Tool and Die Steel S1 bars, consider hardness, wear resistance, toughness, machinability, heat treatment capabilities, and the specific requirements of the application to ensure optimal performance and durability.
Tool and Die Steel S1 bars resist corrosion due to their alloy composition, which includes elements like chromium and molybdenum. These elements form a protective oxide layer, enhancing resistance to oxidation and rust.
Die steel and tools About 0.50–0.60% carbon, 2.75–3.25% nickel, 1.20–1.60% manganese, 0.90–1.40% molybdenum, and trace amounts of silicon and vanadium make up S1 Bars, shock-resistant tool steels. These components offer superior durability and impact-resistant crack resistance. After heat treatment, S1 steel usually reaches a hardness of 56–60 HRC and exhibits high tensile strength and ductility. It is appropriate for demanding cold and hot work applications because it works well at both low and high temperatures and has good hardenability and wear resistance.
