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.

COROCARB NI PLUS

NORMBEZEICHNUNG

Fülldrahtelektrode DIN-EN 14700 ¾ T Ni 20-55-CGZ

EIGENSCHAFTEN

COROCARB–NIFD-PLUS ist ein unter Schutzgas zu verschweißender Fülldraht auf der Basis von Ni-Cr-B-Si mit eingelagerten vorwiegend sphärischen (kugeligen) Wolframschmelzkarbiden (SFTC). Das extrem harte SFTC zeigt eine überwiegend feine Struktur. Dadurch bedingt lassen sich bei extremen Anwendungsfällen zum Teil erhebliche Standzeitverbesserungen erzielen. Neben einer sehr guten Hitze- und Korrosionsbeständigkeit besitzt die Legierung COROCARB–NIFD-PLUS auch eine hervorragende Abrasionsbeständigkeit.

ANWENDUNG

Speziell entwickelt für die Auftragung an Werkzeugen in der Tiefbohrindustrie, Tunnelvortriebsmaschinen, sowie an ferritischen und austenitischen Teilen in der Chemie- und Lebensmittelindustrie. Das Schweißgut ist nur noch bedingt schleifend zu bearbeiten.

Datenblatt

COROCARB NIA

CLASSIFICATION

Welding Rod DIN-EN 14700 ¾ T Ni 20-55-CG

GENERAL CHARACTERISTICS

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