Stainless Steel AISI 304L
AISI 304L stainless steel is an austenitic stainless steel formulated for primary forming into wrought products. 304L is the AISI designation for this material.
The “L” in 304L can be interpreted as meaning extra-low carbon. This difference of 0.05% carbon content produces a slight, but marked, difference in the performances of the two alloys.
