COROCARB NI
CLASSIFICATION
DIN EN 14700 | DIN 8555
T Ni20 | MF 21-55-CGTZ
GENERAL CHARACTERISTICS
COROCARB Ni is a cored metal wire filled with fused tungsten carbide and a Ni- B- Si- matrix for semi-automatic welding application. COROCARB NI was developed to protect surfaces where extreme abrasive wear in combination with corrosion are encountered. The deposit alloy consists of up to 62% FTC (W2C) and 35 - 40% Ni- B- Si- matrix. The alloy has a low melting range of between 900 – 1050°C (1.652 – 1.922°F) and flows extremely well and leaves a smooth and clean surface. The matrix is highly resistant to acids, bases, lye’s and other corrosive media. Be sure that to choose amperage and voltage as low as possible to avoid decay of the tungsten carbides.
APPLICATION
Repairing & hardfacing ferritic and austenitic steel tools and machine parts (steel castings). Specially developed for welding on tool joints and stabilizers in the petroleum industry.

Corodur Fülldraht GmbH may change the characteristics of the wire without notice. Statements on composition and application are just for the applier’s information. Statements on mechanical properties always refer to the all-weld-metal according to valid standards. We recommend the applier to check our products for their special application autonomously.
