PM Core damascus - pyramids

Stainless core damascus with powder steel PM12Cr16V as the core layer in the pyramid pattern.
The PM12Cr16V was developed for use in knife blades and achieves up to 64 HRC with suitable heat treatment.

This damascus combines a damascus appearance with a high-performance core layer for premium cutting tools.

Properties

• Very high wear resistance
• Good machinability and good sharpenability
• Very high final hardness possible
• Excellent polishability

About 1 mm of material should be removed from the outer contour due to the impact edge.
Before hardening, the damascus should have at least 1 mm thickness at the cutting edge.

Chemical analysis (core layer PM12Cr16V)

• C: 1,2% | Cr: 16% | Mo: 2,5% | V: 1,75% | W: 0,1%
• P: 0,03% | S: 0,003%

Our "PM12Cr16V steel" heat treatment recommendation:
Hardening:

• Oxidation protection required
• Hardening temperature: 1080°C - 1120°C
• Quenching medium: air / compressed air or gas
• Cryogenic treatment: required for high hardness
• Tempering: 150°C - 200°C
• Achievable hardness: 60 - 64 HRC

Annealing: Hold for 2 hours at 900°C, then cool slowly
Caution! Stainless core layer steel: Do not perform "plate quenching"! This can cause the core layer to tear away from the outer layers (no delamination). There is also an increased risk of cracking in the core layer during deep freezing, especially with liquid media such as LN2 or with dry ice pellets (uneven cooling).

Etching recommendation

High-gloss polish, then in 33% hydrochloric acid.

Finish
rolled & annealed
