COROCARB NIA PLUS

CLASSIFICATION

Stick Electrode DIN-EN 14700 ¾ T NI 20-55-CG

GENERAL CHARACTERISTICS

COROCARB–NIA-PLUS is a cold rolled, formed, closed seam nickel tube filled with spherical fused tungsten carbide (SFTC) and Cr, B and Si for oxyacetylene application. The deposited alloy consists of approximately 65% SFTC and 35% Ni-Cr-B-Si-matrix. COROCARB–NIA-PLUS wets easily and has excellent flow producing a smooth, clean surface. COROCARB–NIA-PLUS has a low melting point of approx. 900 – 1050°C. The overlay is extremely resistant to acids, bases, lye’s and other corrosive media and other excessive wear conditions.

APPLICATIONS

Hardfacing on ferritic and austenitic steels (steel casings), overlaying mixer blades and conveyors & screws in: chemical &
dye industry and food industry. Recommended for hardfacing rock bits and stabilizers in the petroleum industry.

RECOMMENDED WELDING DIRECTIONS

The surface to be hardfaced should be clean and free of rust, scale or grease and other dirt, preferably by grinding or shot blasting. Deposits should be made using a gas flame with a neutral to slight acetylene excess. To avoid puddling and overheating, sweat deposits on the base metal with minimum penetration.

TYPICAL HARDNESS

SFTC: > 3000 HV
Ni-Cr-B-Si-Matrix: approx. 450 - 520 HV0,1
