8.Hardness & Tempering Curve Graph:
9.Characteristics:
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.
ADVANTAGES:
Excellent machinability.
Outstanding resistance to wear and galling.
Hardening is safe and easy.
Forging:
Heat slowly and uniformly to 700°C then more rapidly to 900/1050°C. After forging cool slowly, preferably in a furnace.
Heat Treatment:
Annealing:
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.
Hardening:
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.
Tempering:
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.
