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.

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

Heat Treatment

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.

Final Grinding

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.
