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.

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

Heat slowly to 700°C and then more rapidly to 900-1050°C.  After forging cool slowly, preferably in a furnace.

As this grade is supplied in the annealed and machinable 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.

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.

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.

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
Hardness [HRc] 65 63 61 60

Heat treatment temperatures, rate of heating, cooling and soaking times will vary due to factors such as the shape and size of each component. Other considerations during the heat treatment process include the type of furnace, the quenching medium and work piece transfer facilities. Please consult a heat treatment specialist for full guidance on heat treatment.

Ensure to select the correct grade of wheel in consultation with a grinding wheel manufacturer. The grinding wheel should be in good condition by means of a suitable dressing tool. Wet grinding is a preferable option using a copious supply of coolant. If dry grinding is resorted to then use a soft wheel.

X210CrW12 steel is supplied in accordance with our ISO 9001:2008 registration.
