Outstanding H11 Mold Steel Mechanical And Physical Properties - China

H11 mold steel is a hot-work tool steel belonging to the chromium-molybdenum-vanad ium alloy system, characterized by fine and uniformly distributed carbides.

This material exhibits high hardenability, excellent resistance to thermal fatigue and erosion, and stable cold and hot workability.

It demonstrates high hot strength and oxidation resistance at medium temperatures, while also offering high toughness and wear resistance.

Mechanical Properties

The mechanical properties of H11 mold steel include a tensile strength of 1792 MPa, a yield strength of 1482 MPa, an elongation of 8%, an impact toughness ranging from 13.6 to 33.9 J/cm², and a hardness range of 52 to 57 HRC.

Physical Properties

The coefficient of thermal expansion for H11 mold steel varies with temperature: 11.7 × 10⁻⁶ m/(m·K) at 20–100°C and 12.9 × 10⁻⁶ m/(m·K) at 20–700°C.

Its thermal conductivity is 29.8 W/(m·K) in the annealed state and 26.7 W/(m·K) in the quenched and tempered state at 20°C; at 700°C, it is 33.5 W/(m·K) in the annealed state and 30.4 W/(m·K) in the quenched and tempered state.
