DAIKOWS 309H
SAW
- AUSTENITIC STAINLESS STEELS
309H
Description
Solid wire for high temperature applications, dissimilar joints and for overlaying
High 0.04%-0.08% carbon version of 309 stainless steel consumables for high-grade applications service temperature for analogous, heat resisting rolled, forged and cast steels as well as for heat resisting,
ferritic CrSiAl steels. Mainly used in annealing shops, hardening shops, steam boiler construction, the crude
oil industry and the ceramics industry. Austenitic deposite with a ferrite content of approx. 8 %.
Preferably used for applications involving the attack of oxidizing gases.
Scaling resistance up to +1000 °C.
