AISI 304 (1.4301, S30400) Stainless Steel Tubing | AISI 304L (1.4306, 1.4307, S30403) Stainless Steel Tubing
Grade 304/304L (UNS S30400/S30403, EN 1.4301/1.4307) is most widely used Austenitic stainless steel. Grade 304L is a low carbon 304, which is a common practice for 304L to be dual certified as 304 and 304L. The low carbon chemistry of 304L combined with an addition of nitrogen enables 304L to meet the mechanical properties of 304. Grade 304L often used to avoid possible sensitization corrosion in welded components.
