Key H13 Mechanical Properties Data Sheet Insights For Tool Engineers - China

H13 Mechanical Properties - Complete Data for Die Design and Material Selection H13 hot work tool steel (W-Nr.

1.2344, JIS SKD61, GB 4Cr5MoSiV1) is selected worldwide because its mechanical properties stay reliable under the combined attack of heat, pressure and abrasion.

Below is a practical overview of H13 mechanical properties in the conditions Songshun supplies.

Room-temperature properties (hardened and double tempered to 45-48 HRC):

- Tensile strength: approximately 1600-1800 MPa

- Yield strength (0.2% offset): approximately 1300-1500 MPa

- Elongation: 9-12%

- Reduction of area: 30-40%

- Charpy V-notch impact energy: 15-25 J (room temperature)

- Elastic modulus: about 210 GPa

- Density: 7.78 g/cm3 Elevated-temperature performance:

- Hot yield strength at 600°C remains around 700-900 MPa

- Retained hardness at 600°C: 40-45 HRC after proper tempering

- Resistance to softening during repeated thermal cycles is the grade's signature trait Physical properties:

- Thermal expansion (20-600°C): approx.

12.5-13.0 x 10-6/K

- Thermal conductivity at 20°C: about 28 W/m·K

- Critical points: Ac1 approx.

815°C, Ms approx.

340°C How processing shapes the properties:

- ESR refining raises transverse toughness and fatigue strength

- Proper double (or triple) tempering stabilizes the microstructure

- Uniform UT-verified sections prevent property scatter in large dies All values above are typical; certified data per heat is supplied with EN 10204 3.1 documents.

Songshun provides H13 bar, plate and blocks with mechanical test reports, heat treatment charts and full traceability.
