Baker Forge CopperMai STAINLESS Nitro-V Core, 394 x 60.3 x 4.55 mm

Baker Forge & Tool Specialty Steel: CopperMai Stainless Core Nitro-V

"Beauty of Carbon, Performance of Stainless"

This billet layout uses our triple alloy Coppermascus cladding over a stainless Nitro-V core. The high contrasting colors really make a super unique look! These cores can be etched black or left bright! 

Billet is 15.5 x 2.375 x 0.179" or approx 394 x 60.3 x 4.55 mm in size, weighting in at 880 grams. The billet is marked "5 - CopperMai Stainless Core Nitro-V"

Coy Baker and his team are creating some truly stunning specialty steels, we are super excited to offer these in Australia:

Specs:

- Coppermascus cladding (1084/Copper/15n20) with Nitro-V core (Be sure to check our Heat Treating page for details on how to HT this material) 

- Flat Ground

- All bar edges are ground back to clean steel 

- Billets come fully annealed 

- These are for stock removal, not to be forged due to chance of delamination between layers AND BEING STAINLESS core.

** This is an advanced, expensive steel with san mai construction. This is not a beginner-steel. There are no refunds for messing up the heat treatment and splitting them, or forging and delaminating the billets ***

Special heat treat instructions from Baker Forge: READ IN FULL

Nitro-V Stainless Cores:

1. ​Place blade in stainless foil with double folded edges
2. Pre heat oven to 1900 F (1038 C) and let the oven equalize at temp for 20-30 minutes
3. Load blade(s) into kiln and wait for oven to rebound to 1900 F (1038 C) then 15 minute soak.
4. Quench between two aluminum plates and use compressed air to cool down the blade. *critical step* 

Snap Temper:

Immediately snap temper the steel at 300F (149 C) for 30-60 minute to relieve stress. (This step is critical to ensure the cladding and core do not tear themselves apart due to stress and different movement rates during the quench)

Cryo:

Following the snap temper go into dry ice or liquid nitrogen for 1 hour, this step reduces Retained Austenite and gives full hardness for the core. (A freezer treatment will not be effective because of the snap temper)

Full Tempering:

After cold treatment complete two temper cycles. First temper cycle at 300F (149 C) for 2 hours then second temper at 350F (177 C) for two hours will yield 63Rc, adjust final temper to achieve desired hardness desired.
