DAIKOWT 309H
GTAW
- AUSTENITIC STAINLESS STEELS
309H
Description
Rod for high-temperature applications, dissimilar joints, and overlay.
High carbon version (0.04–0.08%) of 309 stainless steels, developed for high-temperature service applications on similar heat-resistant steels, both rolled and forged or cast, as well as for heat-resistant Cr-Si-Al ferritic steels. It is widely used in annealing and quenching plants, steam boiler construction, and in the crude oil and ceramics sectors. The austenitic deposit contains about 8% ferrite. These rods are suitable for applications involving oxidizing gas attack and offer oxidation resistance up to +1000 °C.
