AISI D2/ ASTM D2

DIN 1.2379

ASTM A681

SAE J437

SAE J438

Available forms:

D2 round/square bar

D2 plate

D2 Flats

Chemistry composition:

Physical and Mechanical Properties:

Density:7.72 to 8.0 g/cm3

Thermal expansion at 20-200°C : 10.6  10⁶m/(m*K)

Hardness, Rockwell C: 57-59 HRC

Thermal Conductivity at 20-700°C: 16.7-24.2 W/(m*K)

Applications:

AISI D2 tool steel is ideal for threading rolls and dies, icy trimming, cutting and stamping tools such as blanking Dies, Burnishing Tools, Coining Dies, Drawing Dies, Swaging Dies, Threaded Rolling Dies, Trimming Dies

Features:

ASTM D2 is the superior to D3 due to high alloys properties. The 12 % Chromium and 0.90% addition of Vanadium making it a high wear resistance and toughness.
