Characteristics of A681 D3 Mold Steel
AISI D3 mold steel (also known as DIN 1.2080, JIS SKD1) is a high-carbon, high-chromium cold-work tool steel that complies with the ASTM A681 standard.
High Wear Resistance:
Due to the high volume of hard carbides in the steel matrix, D3 steel exhibits excellent resistance to abrasive and adhesive wear, making it suitable for applications requiring high wear resistance, such as blanking dies and shear blades.
Moderate Toughness:
D3 steel has moderate toughness, suitable for applications requiring a balance of toughness and wear resistance. Compared to higher-toughness steels (e.g., A2), its toughness is lower, but it outperforms many low-alloy steels in wear resistance.
High Compressive Strength:
D3 steel possesses excellent compressive strength, making it ideal for molds and tools subjected to high mechanical pressure.
Dimensional Stability:
During heat treatment, D3 steel demonstrates good dimensional stability, reducing the risk of deformation.
Corrosion Resistance:
After polishing, D3 steel offers some corrosion resistance, though not as high as D2 steel, making it suitable for applications requiring mild corrosion resistance.
