COROCARB A

CLASSIFICATION

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

GENERAL CHARACTERISTICS

COROCARB–A is composed of a special pre-alloyed tube filled with coarsely grained Fused Tungsten Carbide (FTC). The FTC has an exceptionally high hardness of over 2360 HV0,4 giving extended wear protection to hardfaced areas. For special hardfacing on machine parts of unalloyed, low alloyed or cast steel with a carbon content up to 0,45%. A higher carbon content could lead to cracking. Depending on the size and composition of the area to be hardfaced, the proper rod diameter and grain size should be chosen. If the area will encounter heavy abrasion a small grain size is recommended.

APPLICATIONS

For hardfacing and repairing tools and machine parts exposed to wear in: Mining, Road Construction, Ceramic, Petroleum, Excavation and Dredging.

RECOMMEND WELDING DIRECTIONS

The area to be hardfaced should be free of rust, scale, grease or other dirt. The burner nozzle should be held at a shallow angle to the work area with a neutral to slightly acetylene excess flame. To avoid overheating, the work area should be slightly wetted and the tube metal should not come into contact with the centre of the flame.
Depending on the base metal and the size of the work area a preheating temperature between 350 – 500°C (660-930°F) is advised. Detailed welding directions are available upon request.

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.
