1.2379 Cold Work Tool Steel

タイトルまたは説明

This alloy is one of the Cold Work, high carbon, high chromium type tool steels. D2 is a deep hardening, highly wear resistant alloy. It hardens upon air cooling so as to have minimum distortion after heat treatment.
Properties：Vacuum degassing, pure steel, spheroidized annealing suitable for cutting, no quenching cracking, superior wear resistance and toughness.
Applications：Widely used in the thickness of less than 2mm plate, stamping die, punching die, forming die, trimming die, thread rolling die, woodworking blade, food processing tools and measuring tools.
FORMING：Forming is done by forging and machining
HEAT TREATMENT：Preheat very slowly to ***0 F and then increase temperature to ***0 F. Hold at ***0 F for *0 to *5 minutes and air cool (air quench).
FORGING：Forging may be done in the range of ***0 F down to ***0 F. Do not forge below ***0 F.
COLD WORKING：Cold working by conventional methods may be done with the alloy in the annealed condition.
ANNEALING：Anneal at ***0 F to ***0 F followed by slow furnace cooling at *0 F per hour or less.
TEMPERING：Tempering may be done in the range of **0 F for Rockwell C *1 to ***0 F for Rockwell C *4.
