CORODUR® 733

CLASSIFICATION

DIN EN 14700 | DIN 8555
T Z Fe115 | MF 10-70-GT

GENERAL CHARACTERISTICS

CORODUR 733 is a flux cored wire electrode containing extremely hard Cr-carbides and niobiumcarbides embedded in a Fe- Cr- Nb- B- matrix with complex carbides. The weld deposit is very fine-grained and extremely hard. A hardness of 67 HRc in the first layer is possible. It is suitable for hardfacings of applications requiring high abrasion resistance with at the same time minor impact resistance and wear resistance up to a working temperature of up to 450° C

APPLICATION

Worm conveyer screws, sand-preparing plants, dredgers, mixers, ceramic industry, fan baffles, pump casings, briquetting plants etc.
