304L (1.4307) Stainless Steel

304L grade stainless steel is one of the most widely used stainless steel grade. This grade is very close to 304 grade stainless steel and it is also shown as 1.4307 or X2CrNi18-9 according to EN norm. It is also known as UNS S30403 according to UNS norm. Name 304L can be explained by separating 304 and L. L means Low and low indicates the low carbon content of the material so 304L means 304 grade with low carbon content and the rest of the properties are nearly same with 304 grade stainless steel. 304L grade material has a slightly better weldability then 304 grade because of lower carbon content.


304L grade stainless steel has a lower carbon content then %0.03. 304L grade can be used in all applications where 304 grade is also accepted. Finally, the lower carbon content allows this grade to have a better elasticity, so if better elasticity and better weldability is required, 304L will be a better choose then 304 grade. In Birçelik warehouse, you can find 304L grade in UGIMA and UGIMA X versions and these versions has a better machinability then the standard 304L grades.
