Tool Steel
D2 BS EN ISO 4957
Description:
D2 tool Steel is an air hardening, high carbon, and high chromium tool steel, heat
treatable to HRC 60-62. D2 is widely used in cold work applications requiring very high wear resistance.
It offers excellent abrasion resistance and compressive strength combined with mild corrosion resistance
and moderate toughness. It is very deep hardening and shows good dimensional stability after proper
treatment. D2 can be supplied in many finishes including, hot rolled, part pre machined and fine machined
condition.
Applications include Cutting Tools for: Blanking, fine-blanking, punching, cropping, shearing, trimming, cold
shears. Shredding knives for waste plastics. granulator knives, circular shears, clipping, trimming tools for
forgings. Wood milling cutters, reamers, broaches. Forming Tools for: Bending, forming, deep-drawing,
rim-rolling, spinning and flow-forming. Coining dies, Cold extrusion dies, punches, tube and section
forming rolls; plain rolls dies for moulding of: Ceramics, bricks, tiles, grinding wheels, tablets, abrasive
plastics. Thread-rolling dies, cold-heading tools, crushing hammers, swaging tools, gauges, measuring tools,
guide rails, bushes, sleeves, knurling tools, sandblast nozzles.
