- AUSTENITIC STAINLESS STEELS
318
Description
Rod for stabilized austenitic stainless steels
The chemical composition of this rod is identical to that of 316, except for the addition of niobium. Niobium provides resistance to chromium carbide precipitation, thereby enhancing resistance to intergranular corrosion. It is also used for depositing corrosion-resistant overlays and for insertions on medium alloy carbon steel valve seats, as well as for joining austenitic stainless steels containing molybdenum stabilized with titanium or niobium. It resists intergranular corrosion and moisture up to 400 °C.
