Product Description:

D6 Cold Work Mould Steel Round Bars DIN1.2436

AISI D6 tool steel is a high-carbon, high chromium tool steel alloyed with tungsten that is characterized by high compressive strength, high wear resistance, high surface hardness and good hardening stability

 

Specification of D6 tool steel

1.Diameter:60mm~600mm 

2.Length:1-6.5m or as customer's request

The chemical composition of D6 tool steels is outlined in the following table.

ElementContent (%)
Iron, Fe83.05
Chromium, Cr12.5
Carbon, C2.05
Tungsten, W1.3
Manganese, Mn0.8
Silicon, Si0.3

Forging

D6 tool steel is heated slowly and uniformly to 700°C (1292°F) and then more rapidly to 900-1050°C (1652-1922°F).

Annealing

D6 tool steel is then annealed at 800-840°C (1472-1544°F) and cooled. Hardness of the steel after annealing will be approximately 225 Brinell.

Stress Relieving

Stresses from D6 tool steel can be eliminated before hardening by heating up to 650-700°C (1202-1292°F), if machining operations have been heavy. The steel is then allowed to cool slowly.

Hardening

D6 steel is pre-heated slowly to 750-800°C (1382-1472°F) and thoroughly soaked. Heating is then continued till the final hardening of 950-980°C (1742-1796°F), followed by air or oil quenching.

Tempering

The steel is heated uniformly and thoroughly at the selected tempering temperature. Double tempering can also be carried out with intermediate cooling to room temperature.
