FE-SEM micrographs of ASTM A36 and AISI 304L after exposure to solar salt at 390 C for 7, 14, and 21 days. Instead, depth profiles of the chemical composition obtained by GDOES were employed. The results are shown in Fig. 10, where iron and oxygen were displayed for carbon steel.
This article will introduce the differences between 304 and 304L stainless steel (304 vs 304L) from chemical composition, mechanical properties, corrosion resistance and weldability. AISI 304L stainless steel is an ultra-low carbon version of SS 304 (Carbon content: ≤ 0.08 %). "L" is short for "Low carbon" and the maximum carbon
