Thermanit 309 H

Solid wire of G 22 12 H / ER309 (mod.) type for similar, 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. Results in an austenitic microstructure deposited with a ferrite content of approximately 8%. Preferably used for applications involving the attack of oxidizing gases. The fi nal layer of joint welds in CrSiAl-steels exposed to sulfurous gases must be deposited using a 25/4
grade welding consumable.
