Cru Forge V Steel by Crucible


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

We buy this in 36" lengths and sell it in 12", 24",  and 36"lengths.

 If you buy 1, you will get a stick 12" long by the width and thickness shown.

 If you buy 2, you will get a bar that is 24" in legnth.

 If you buy 3, you will get a bar that is 36" in legnth.

**If you buy 2 or 3 and want 12" length pieces, please specify in the comments section that you would like them cut into 12" pieces.

**Advertised price is for 1qty 12" piece

 

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.

 

CRA means cold rolled annealed and is important to be in the description. It means the steel was pressure rolled while cold but was annealed again to relief the stress and take it to the softest state from rolling under tremendous pressure. 

 

HR means hot rolled and this steel was rolled to thickness usually during the smelting process but maybe later. The steel generally will be half or nearly fully hard depending on the type. It may often have mill scale residue. This steel can be easily forged. It can also be ground via stock removal. Drilling a hole in the tang maybe hard to do with out a carbide bit. 

 

HRA is the same but the steel was later annealed to relieve stress and make it as soft as possible for easier machining. 

 

Several companies produce "powder" smelted steels. This is a premium smelting process that improves the mixing of alloy content and generally produces a finer grain structure as a result. The powder steels are nearly always annealed and can be assumed to annealed unless noted otherwise.
