CLASSIFICATION

DIN EN 14700 | DIN 8555
T Fe8 | MF 6-55-GP

GENERAL CHARACTERISTICS

The welding deposit is martensitic with embedded Nb- carbides. It has a high resistance to pressure and it is very crack resistant. Due to the Nb - carbides, with a hardness of 2700 HV, the welding deposit has an additional resistance to abrasion wear. The preheat temperature and the interpass temperature should be chosen according to the base material.

APPLICATION

Cement rolls, crusher rolls and hammers, briquetting plants, ceramic industry

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.

GENERAL CHARACTERISTICS

CORODUR 721 is a flux cored wire with alloyed Fe-B-Cr-weld metal with a martensitic carbide structure. It is suitable for highly abrasion resistant hardfacings that are exposed to minor impact and high wear at temperatures of up to 450°C. Due to its high hardness the hardfacing should not exceed 4 mm thickness.

APPLICATION

Feed screws, sand preparation plants, wear plates, ceramic industry, mixer parts

CLASSIFICATION

DIN EN 14700

Special alloy<

GENERAL CHARACTERISTICS:

CORODUR 720 is a relatively low alloyed flux cored wire. The weld deposit is ideal for parts subject to impact, metal to metal friction and severe fine particle abrasion/erosion actions. It gives a full martensitic deposit which is rich in iron-borides and iron carbides. The working temperature should not exceed 200°C in order to keep wear minimal.

APPLICATION

Dredges, concrete pumps, driving Screws, fine particle (sand) wearing parts.
