INOX R 29/9
Description and application:
Rutile, austenitic ferritic electrode for welding dissimilar and »difficult to weld« steels. Suitable for interpass
hardfacing. Because of high mechanical strength and starain hardenability suitable for wear resistant buildups on
gear wheels, shafts,… The weld metals has excellent cavitation and cracking resistance.
Base materials:
- Hardwelding steels
- High-strength unalloyed and alloyed steels
- Structural, spring, tool and heat treatable steels
- High manganese steels
Heat treatment:
Preheating and postweld heat treatment as required by the base metal.
