8.Hardness & Tempering Curve Graph:



Excellent wear resistance and edge holding ability

High surface harness after heat treatment

Medium toughness

Good through hardening properties and dimensional stability

High compressive strength


10. Applications:

Cutting and drawing tools of high wear resistance,

Rolls with high dimensional stability

Deep drawing tools

Tools of wire

Bar and tube production

Cold shear blades for thin sheets.



Excellent machinability.
Outstanding resistance to wear and galling.
Hardening is safe and easy.


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

Heat Treatment:

Anneal at 800°/840°C and slow furnace cool. Hardness after annealing will be approx. 225 brinell.
Stress Relieving:
If machining operations have been heavy or if the tool has an unbalanced section, remove stresses from D6 tool steel before hardening by heating up to 650°/700°C, equalise, then cool slowly.
Pre heat slowly to 750/800°C and thoroughly soak. Continue heating to the final hardening temperature of 950°/980°C and allow the component to be heated through. Cool in air or quench in oil.
Heat uniformly and thoroughly at the selected tempering temperature and hold for at least one hour per inch of total thickness. Double tempering should be carried out with intermediate cooling to room temperature.
