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 FE

CLASSIFICATION

DIN EN 14700 | DIN 8555
T Fe20 | MF 21-65-GZ

GENERAL CHARACTERISTICS

COROCARB OA is an open arc tubular wire filled with fused tungsten carbide (FTC) for semi-automatic application, where extreme abrasive wear is encountered. For hardfacing of low alloyed steels that have a maximum of 0,45% carbon (a higher carbon content could lead to cracking). Also for hardfacing and repairing tools and machine parts exposed to wear. The area to be hardfaced should be free of rust, scale, grease or other dirt. Depending on the base metal’s alloy and the size of the area to be hardfaced the advisable preheating temperature should be between 350-500°C (662-932°F). If the voltage and the welding current are kept on the lowest setting possible the tungsten carbide granular will be prevented from melting. During welding, position the arc that the weld metal is deposited in coarse droplets.

APPLICATION

Mining, excavation, earth moving, tunneling shields, road construction, well drilling and deep drilling.

COROCARB E

CLASSIFICATION

Stick Electrode DIN-EN 14700 ¾ E Fe 20-60-CG

APPLICATIONS

For hardfacing unalloyed and low alloyed steels (cast steels) with a maximum carbon content of 0,5%. A higher carbon content could lead to cracking. For welding on most high alloyed steels after a buffer layer is applied. Also for hardfacing tools and machine parts that experience wear in: Mining, Excavation, Well Digging, Road Construction
and Deep Drilling.

RECOMMENDED WELDING DIRECTIONS

Depending on the base metal’s alloy and the area to be hardfaced, a preheating temperature between 350-500°C (662-932°F) is advised. NOTE: Since COROCARB-E is a hollow tube metal filled with fused tungsten carbide powder, the lowest amp setting possible should be used when depositing it in order to avoid any damage to the carbides.
