D3 Tool Steel | High-Carbon, High-Chromium, Cold-Work Steel (UNS T30403)

 

ASTM AISI D3 Tool Steel is a cold work tool steel grade with widely application. D3 is similar with SKD1 Cold work tool steel, no matter in properties or in applications. the cost and price for both D3 and SKD1 steels only have a little different.

Cold work ASTM/AISI D3 tool steel grade in standard ASTM A681-1999

In ASTM A681-199 include the D3 Cold work tool steel, UNS T30403, SAE D3 steel, It is standard specification of cold work tool steels for cold work tool, mould, die application, such as hot rolling or hot forging steels or cold drawn steel grade.

Heat Treatment AISI Cold work alloy Steel D3 material grade

D3 steel material heat treatment including the heating rate, soaking times, cool, these such as the different shape and size of each D3 steel component. Preheat to 900°C, keep enough time, Re-heat temperature 800-1040°C and again soak for three to four hours. Allow to cool in the furnace to room temperature

Application of AISI D3 cold work tool steel Materials grade

D3 steel application such as complex blanking and forming tools for long runs and for hard and abrasive materials. It is commonly, informs the for other applications to the as brick and tile mould liners, master hobs for cold hobbing plastic moulds, tabletting punches and sleeves for corrosive powders.
