Mat.No. 1.2367/DIN X38CrMoV5-3
Hot work tool steel. Secondary hardening steel with high strength and wear resistance in hot. Good tempering resistance. High hardenability and thoughness. Tools can be water cooled.
Designation by Standards

| 1.2367 | X38CrMoV5-3 | - | - |
Chemical Composition (in weight %)
| C | Si | Mn | Cr | Mo | Ni | V | W | Others |
| 0.38 | 0.40 | 0.40 | 5.00 | 2.95 | - | 0.50 | - | - |
Applications
Wear resisting tools, pressure die casting tools, pressing tools for light and heavy metal. For the highest requirements, we recommend UTOPMO7 ESR EFS.
Physical properties (avarage values) at ambient temperature
Density [g/cm3]:7.83
Thermal conductivity [W/m.K]:25.0
Thermal conductivity [W/m.K]
| 20oC | 500oC | 600oC |
| 25.0 | 28.5 | 29.3 |
Coefficient of Linear Thermal Expansion 10-6 oC-1
| 20-100oC | 20-200oC | 20-300oC | 20-400oC | 20-500oC | 20-600oC | 20-700oC |
| 11.5 | 12.0 | 12.2 | 12.5 | 12.9 | 13.0 | 13.2 |
Soft Annealing
Heat to 800-840oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 235.
Stress Relieving
Stress relieving to remove machining stresses should be carried out by heating to 650oC, holding for one hour at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.
Hardening
Harden from a temperature of 1030-1080oC followed by air, oil or warm bath (500-550oC) quenching. Hardness after quenching is 53-57 HRC.
Tempering
Tempering temperature: See the table bellow.
Tempering Temperature (oC) vs. Hardness (HRC) vs. Tensile Stregth (N/mm2)
| 100oC | 200oC | 300oC | 400oC | 500oC | 550oC | 600oC | 650oC | 700oC |

| 2140 | 1980 | 1910 | 1845 | 2010 | 2050 | 1845 | 1360 | 995 |
Forging
Hot forming temperature: 1080-900oC.
