Applications
X210CrW12 is suited to applications where maximum wear resistance is required. Applications such as blanking tools, drawing tools, drawing dies, mandrels, forming tools, shear blades and press tools.
Analysis
| Carbon | 2.00-2.30% | Chromium | 11.00-13.00% |
| Manganese | 0.30-0.60% | Tungsten | 0.60-0.80% |
| Silicon | 0.10-0.40% | Phosphorous | 0.03% max |
| Sulphur | 0.03% max |
Forging
Heat slowly to 700°C and then more rapidly to 900-1050°C. After forging cool slowly, preferably in a furnace.
Annealing
As this grade is supplied in the annealed and machineable condition re-annealing will only be necessary if it has been forged or hardened. Anneal the steel at 800-840°C and slow furnace cool. Hardness after annealing will be approximately 225HB.
Stress Relieving
When machining operations have been heavy or if the tool has an unbalanced section, remove stresses before hardening by heating up to 650-700°C, equalise, cool slowly.
Hardening
Pre heat slowly to 750-800°C and soak thoroughly. Continue heating up to the final hardening temperature of 950-980°C, allow the component to be heated through. Cool in air or quench in oil. X210CrW12 is suitable for vacuum (high speed gas) hardening.
Tempering
Heat the steel uniformly and thoroughly at the selected tempering temperature and hold for at least one hour per 25mm of total thickness. Double tempering of X210CrW12 should be carried out with intermediate cooling to room temperature.
| Temperature [°C] | 100 | 200 | 300 | 400 | 500 | 600 |
| Hardness [HRc] | 63 | 62 | 60 | 58 | 56 | 48 |
