TGC88 is an improved version of DC53. It is produced via EAF+LF+VD or EAF+LF+VD+ESR metallurgical processes. Compared with DC53, it features higher toughness and wear resistance, as well as excellent tempering resistance. Its hardness can reach 62–64 HRC, which greatly extends service life.
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.
