Chrome Tool Steel

AISI D2High Carbon/High Chrome Tool SteelAs the result of its special annealed structure, developed and tested over a period of severalyears, AISI Type D2 is the ideal grade for maximum production runs. Its machinability is superiorto any of the similar types of tool steel. It also has excellent wear-resistance and deep hardeningproperties, and high compressive strength. Use D2 for applications requiring long runs and closetolerances. Use it for tools and dies for blanking, punching, forming, cold-extruding, and otheroperations 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 pctcarbon tool steel.Dimensional Stability - Tests on this grade normally show a slight amount of contraction afterhardening with the part in the as-quenched condition or tempered below 900F. Tempering atapproximately 925F usually eliminates this contraction and brings the part virtually back to itsoriginal size. D2 has the minimum distortion in heat-treatment as compared with other tool steels.Typical AnalysisCarbon 1.55 Molybdenum 0.080Chromium 12.00 Vanadium 0.090AnnealingUse a controlled-atmospheric furnace or pack in some inert material in a sealed container toprevent decarburization.
