Features and Uses of D2 Cold Work Tool Steel
D2 is an air hardening high carbon, high chromium type tool steel which
offers very high wear resistance, yet it is tough and machinable.
It hardens in air up to large sections with a low order of movement and offers a
measure of corrosion resistance when polished.
D2 has low distortion characteristics which are superior to the more commonly
used oil hardening (O1) and medium alloy (A2) grades. It also exhibits
considerably better wear resistance than these grades, but its comparative
toughness is lower than either.
Typical Applications
D2 is used for tools operating under conditions of severe wear and abrasion
or as an alternative to oil hardening tool steels when longer runs are required.
Applications include blanking dies and punches for steel sheet and plate, high
silicon transformer materials, stainless steel and iron, brass, copper, zinc and
hard abrasive materials generally.
Deep drawing dies, cupping dies, forming dies.
Sheet metal forming rolls, shear blades for strip and sheet including flying
shears.
Circular cutters for cold rolled strip. Trimmer dies, thread rolling dies, cold
extrusion dies. Broaches, plug gauges, ring gauges, special taps, staybolt
taps.
Brick and tile mould liners. Master hobs for cold hobbing plastic moulds. Cut
moulds for plastics.
