Material Notes:
AK Steel 304L is an extra low-carbon variation of Type 304, that eliminates carbide precipitation due to welding. AK Steel 304L can be used in the "as-welded" condition, even in severe corrosive conditions. It often eliminates the necessity of annealing weldments except for applications specifying stress relief. It has slightly lower mechanical properties than Type 304.
