Material Options:

H13 Tool Steel

A good high strength pre-hardened tool steel which is machined, thru-hardened, and ground dimensionally, then nitride hardened for 72 hours for better wear resistance. H13 is tough and can handle pressure and torque.

D2 Tool Steel

A high carbon/high chrome tool steel with good wear resistance, but low on torque strength. D2 should only be used with 4-piece designs where the stud is manufactured from 4140, H13 or another high torque steel.

CPM® 9V Tool Steel

A new generation tool steel with a high percentage of Vanadium Carbide developed for high wear (abrasive) applications. It resists wear from abrasive fillers in resin. (Construction: Carbon 1.8%, Manganese 0.50%, Silicon 0.9%, Chromium 5.25%, Molybdenum 1.3%, Vanadium 9.0%.)

CPM® 420V Tool Steel

Crucible's CPM® 420V is a new stainless tool steel best suited for corrosion resistant applications. CPM® 420V is a higher performance upgrade from CPM® 440V. Corrosion resistance is significantly better than CPM® 440V. Wear resistance is about 25-50% better than CPM® 440V, due to the higher Vanadium Carbide content of CPM® 420V (9% Vanadium vs. 5.5-6% in CPM® 440V).

CPM® M4 Tool Steel

Crucible's CPM® M4 is a high Vanadium, special purpose, high speed steel exhibiting better wear resistance and toughness than D2 or CPM® 9V. CPM® M4 has a hardness rating of 64.0. (Construction: Carbon 1.42%, Chromium 4.0%, Vanadium 4.0%, Tungsten 5.5%, Molybdenum 5.25%.)
