- AUSTENITIC STAINLESS STEELS
347
Description
Rod for stabilized austenitic stainless steels
These Cr-Ni rods are stabilized with niobium and are suitable for welding steels stabilized with titanium or niobium. The presence of niobium reduces sensitivity to intergranular corrosion even under severe conditions. They are also suitable for cladding mild steels with a buffer layer in 309. Typical service temperatures range from -100°C to approximately 400°C. The higher silicon content compared to standard 347 increases the weld fluidity and enhances the bead appearance.
