Cru Forge V Steel by Crucible

.25"x2"x36"

This steel was developed by Crucible for the forging knife maker.

Cru Forge V is a vandium modified high carbon blade steel specifically designed to offer the forgeability of carbon steels such as W1, 1086 or 52100, while providing improve wear resistance in finished blades. The addition of vanadium promotes the formation of hard vanadium carbides in the micro-structure, adding to the abrasive wear resistance of the material compared to plain high carbon steels.

It may be readily forged and heat treated using standards practices used for high carbon blade steels.

carbon 1.05%
Chromium 0.50%
Vanadium 0.75%
Manganese 0.75%

Forging: 1700F-2000F degrees. Do not forge below 1600F. Slow cool or anneal after forging.

Annealing
Heat to 1450F degrees, hold long enough to make sure the temperature is uniform, slow cool to below 200F.

Hardening
Preheat: heat to 1200-1250F degree, equalize.
Austenitize: Heat to 1500-1550F degrees. equalize. Quench in oil.
Temper: Double temper at 400-500F recommended. Approximate hardness after double tempering is shown below. Actual hardness will depend on hardening temperature and quench rate.

temper:  350  400  425  450  500 550  600
HRC:     62     61    59   58     58   56    55

Thanks to Dan Farr for all the hard work on helping bring this steel to knife makers.
