1. Good dimensional stability.2. Excellent toughness and wear resistance.3. Suitable for high-load blanking and forming operations.
S7 is impact-resistant tool steel with excellent toughness & high strength, produced by EAF+LF+VD+ESR metallurgy. Widely used for punches to bear heavy impact; its use in small plastic molds keeps growing. It can be hardened, air-quenched in most cases with low deformation. Hardness up to HRC58-60, offering high compressive strength (anti-deformation) and great toughness. Suitable for impact-resistant hot-work and cold-work tools.
M2 (SKH‑9) is W‑Mo series 6542 high-speed tool steel (commonly known as white steel). As Tiangong International’s flagship product, it has the world’s highest sales volume. Produced by EAF+LF+VD+ESR melting, it has fine, regular and uniform carbide structure, with good toughness, high red hardness and outstanding wear resistance, as well as hot & cold work formability.
TPM330, also known as ASP2023 or PM23, is a powder metallurgy high-speed steel independently manufactured by Tiangong International, produced in accordance with the 3rd-generation powder metallurgy steel process standard.
