AISI L6 Cold Worked Mold Steel
1: AISI L6 steel introduction
This is one of the special purpose, low alloy tool steel grades, similar to the W group of low alloy tool steels. L6 contains nickel, chromium and molybdenum for a good combination of toughness and hardenability.

6. AISI L6 Tool Steel Heat Treatment
Soft Annealing
Heat to 670-700oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 250.
Stress Relieving
Stress relieving to remove machining stresses should be carried out by heating to approx. 650oC, holding for 1-2 hours at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.
Hardening
Harden from a temperature of 830-870oC followed by oil quenching. Hardness after quenching is 57-61 HRC.
Tempering
Tempering temperature: 400-700oC.
7: Delivery condition
For hot forged or hot rolled bar, usually the delivery condition is hot forged or rolled, annealed, rough turned.
For hot forged plate, usually the delivery condition is hot forged, annealed, milled surface.
For hot rolled plate, usually the delivery condition is hot rolled, annealed, black surface.
