I am being asked by a customer to find this material for his knife blanks. I finally found the source for this. They claim the 6K is "the best" material for knife blades. Said it will hold an edge better and longer. So far, heres the specs:
Resist Seizing and Galling
Stellite® 6B is resistant to the effects of seizing or galling. In many cases, its low coefficient of friction allows sliding contact with other metals without damage by metal pick-up.
Stellite® 6B has been used in equipment where no lubricants were used because of the nature of the product being handled. Sleeves made of Stellite® 6B move smoothly, with a minimum of resistance, even when operating in contact with other metal parts. They have been useful in inaccessible areas where efficient lubrication is impossible. Sleeves and bushings have resisted seizing even when lubricants were diluted by gasoline, cleaning fluids, and other liquids that wash out an oil film. They have operated at peak efficiency even when lubricants decomposed under heat or were destroyed by abrasive particles.
Resist Erosive Wear
Parts made of Stellite® 6B have had long service life, even under constant erosive conditions. This material has outstanding resistance to cavitation-erosion. Stellite® 6B used for steam turbine erosion shields has protected the blades of turbines for over 30 years of continuous service.
Good Impact and Thermal Shock Resistance
Stellite® 6B combines wear and corrosion resistance with good impact strength and resistance to thermal shock.
Resist Heat and Oxidation
High temperatures have little effect on the hardness, toughness, and dimensional stability of these alloys. They are highly resistant to atmospheric oxidation at ordinary temperatures, and have good resistance to oxidation at elevated temperatures.
Excellent Hot Hardness
Stellite® 6B retains high hardness, even at red heat. Once cooled back to room temperature, it recovers its full original hardness.
Corrosion Resistance
In addition to its wear-resistance, Stellite® 6B has good resistance to a variety of corrosive media. This combination of properties makes Stellite® 6B particularly useful in such applications as food handling machinery, chemical equipment, and others where both wear and corrosion resistance are necessary.
Available Forms
Stellite® 6B and Stellite 6K are available in the form of sheet, plate, and fabricated shapes. Stellite® 6B is also available as bar stock.
Heat Treatment
Wrought forms of Stellite® 6B and Stellite® 6K are supplied in the solution heat-treated condition unless otherwise specified. The standard heat treatment is at 2250°F (1232°C) followed by air cooling.
Chemical Breakdown:
Cobalt Balance
Nickel 3% max
Silicon 2% max
Iron 3% max
Manganese 2% max
Chromium 28%-32%
Molybdenum 1.5% max
Tungsten 3.5%-5.5%
Carbon 0.9%-1.4%
So far this is what I have. The company said that 6B has been used for a very long time for knife blades. They also said the 6K if far superior to the 6B. Just wondering if anyone has ever used this material. I'll update with new info as it comes in.
