One bar of Crucible Steel CPM 3V measuring 5.2 x 304 x 914 mm.
CPM 3V steel is a high alloy tool steel with extraordinary toughness, great edge retention and fantastic wear resistance. Made by the Crucible Particle Metallurgy process, CPM 3V has been designed to provide maximum resistance to breakage and chipping in a highly wear resistant tool steel.
CPM 3V is the perfect steel for hard use outdoor knives, and performs very well in knives such as smaller, folding and kitchen that require fine edge holding.
Although not technically a stainless steel, the included 7.5% chromium means that it offers excellent corrosion resistance.
Note: CPM 3V steel comes annealed (soft).
Recommended working hardness 58-61HRC
Higher hardness of 62-63HRC may be used in blades requiring fine edge holding where a reduction in toughness is not critical.
To take advantage of CPM 3V’s high chromium content for stain resistance do not use the manufacturer’s recommended high temperature tempering of over 540°C. Use the heat treatment procedure below with lower temperature tempering.
Recommended Heat Treatment
- Seal blade in double crimped high temperature Stainless Steel Tool Wrap
- Preheat to 850°C, hold for 5 minutes
- Austenitise at 1080°C for 30 minutes
- Plate quench
- Cold treatment; domestic freezer, dry ice slurry, liquid nitrogen – the colder the better
- Temper at 200°C for 2 hours, twice
Recommended working hardness 58 – 61 HRC
