2814-MCG (formerly part 2814-SPL)
Description
Interal Diameter of Pigment Sweeps
Interal Diameter of Pigment Sweeps
Nickel matrix hardface overlay - 57 Rc. Postalloy® 2814-MCG weld deposits consists of chromium borides in a nickel matrix for excellent resistance to low stress abrasion and metal-to-metal wear. The high nickel and chromium content gives this weld deposit good oxidation and corrosion resistance. This alloy is metal-cored, gas-shielded wire designed for application by GMAW. Deposits are smooth with no slag to chip and no ripples. It may be applied to cast iron, carbon and alloy steels, stainless steel, and nickel alloys. Excellent sliding, metal-to-metal wear resistance with unusually good resistance to galling. Very good resistance to atmospheric, steam and salt water corrosion Excellent heat resistance - deposits maintain their hot-hardness up to 1000°F (538°C). Deposits are non-sparking, non-heat treatable, and non-magnetic.
