Nickel – Chromium – Boron Hardfacing Alloys

Weld deposits of these alloys consists of borides and chromium carbides in a nickel matrix for excellent resistance to low stress abrasion and metal-to-metal wear.  The high nickel and chromium content gives these weld deposits good heat and corrosion resistance.

    •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-heattreatable, and non-magnetic.

TYPICAL APPLICATIONS:

Shafts, sleeves, pump parts, impellers, bushings, gauges, guides, cams, rocker arms, screw flights, seal rings, splines, roll guides, lathe centers, conveyor guides.
