IMPORTED Super Die Forgings, For Cold Extrusion Tools, Blanking Stamping Tools, Dimension : 5 To 400 Mm

We are offering die forgings.
Cold work tool steel
aisi d2
high carbon high chrome tool steel
as the result of its special annealed structure, developed and tested over a period of several years, aisi type d2 is the ideal grade for maximum production runs. Its machinability is superior to any of the similar types of tool steel. It also has excellent wear-resistance and deep hardening properties, and high compressive strength. Use d2 for applications requiring long runs and close tolerances. Use it for tools and dies for blanking, punching, forming, cold-extruding, and other operations requiring high compressive strength and excellent wear resistance.
Machinability - d2 has a machinability rating of 65, as compared with a rating of 100 for a 1 pct carbon tool steel.
Dimensional stability - tests on this grade normally show a slight amount of contraction after hardening with the part in the as-quenched condition or tempered below 900f. Tempering at approximately 925f usually eliminates this contraction and brings the part virtually back to its original size. D2 has the minimum distortion in heat-treatment as compared with other tool steels.
Applications
wheels and combs for thread rolling, cold extrusion tools, blanking and stamping tools for high strength materials, mandrels for stepping cold rolling mills, cutting and stamping tools for sheet thicknesses up to 6 mm, precision cutting tools up to 12 mm. Cold pilger mandrels, circular-shear blades, deep-drawing tools, pressure pads and highly wear-resistant plastic moulds.
