Abstract

This invention relates to a niobium-containing austenitic stainless steel. According to the invention, the pitting potential can be increased compared to existing 304L STS by adding trace amounts of niobium, thereby ensuring excellent corrosion resistance, and it is also price-competitive with existing austenitic stainless steels. Furthermore, the impact absorption energy at -196°C can be above 41 J.
