Low-carbon 304L stainless. C<=0.030% prevents sensitisation in welded fabrications without post-weld annealing. Standard welding grade.
X2CrNi19-11 (EN 1.4306 / AISI 304L) per EN 10088. The L (low carbon) variant of standard 304. C<=0.030% eliminates grain boundary chromium carbide precipitation during welding (sensitisation). Can be used in welded condition without post-weld solution annealing for most environments. Preferred over 304 for all welded fabrications.
