Use & Application
GMAW wire for analogous, heat resisting rolled, forged and cast steels as well as for heat resisting, ferritic CrSiAl steels, e.g. in annealing shops, hardening shops, steam boiler construction, the crude oil industry and the ceramics industry. Preferably used for applications involving the attack of oxidizing gases. Scaling resistance up to +1000 °C. Product for high temperature applications. Suitable for dissimilar joints and for overlaying. Preheating and interpass temperatures for ferritic steels 200 – 300 °C.
Alloy type
High carbon version of 309 stainless steel for high-grade applications service temperature.
Austenitic deposited with a ferrite content of approx. 8 %
