What is the cutting speed of Hastelloy c22?
Overview
HASTELLOY Alloy C-22 is a nickel-chromium-molybdenum alloy that has enhanced resistance to pitting, crevice corrosion, and stress corrosion cracking. It resists the formation of grain boundary precipitates in the weld heat affected zone, making it suitable for use in the as-welded condition. C-22 has excellent resistance to both reducing and oxidizing media, and because of its resistance, can be used where "turnover" conditions may occur. It has proven to have excellent weldability and high corrosion resistance as a consumable filler wire and electrode. The alloy has proven effectiveness as a filler wire in many applications. It can be used as a filler wire when other corrosion resistant wires have failed.
C-22 is easily cold worked due to its ductility, and cold forming is the preferred forming method. Since the alloy is generally harder than austenitic stainless steels, more energy is required. 0.28-inch thick plate was heat treated at 2050°F in a rapid quench condition and had an average Olsen Cup depth of 0.49 inches.
