AISI 304 stainless steel (UNS S30400) is the most commonly used material in stainless steels, and is usually purchased in an annealed or cold worked state. Because SS304 contains 18% chromium (Cr) and 8% nickel (Ni), it's also known as 18/8 stainless steel. Type 304 has good processability, weldability, corrosion resistance, heat resistance
Best suited process parameters for welding of AISI 304L and AISI 202 stainless steel of thin plates are current—65 A, welding speed—6 mm/s, CTWD—10 mm and shielding gas—pure argon. This combination of parameter gives the best results for mechanical properties that join the sheets efficiently.
SAE 304 stainless steel is the most common stainless steel. The steel contains both chromium (between 18% and 20%) and nickel (between 8% and 10.5%) [1] metals as the main non- iron constituents. It is an austenitic stainless steel. It is less electrically and thermally conductive than carbon steel. It is magnetic, but less magnetic than steel.
AISI 304L stainless steel is an austenitic stainless steel formulated for primary forming into wrought products. 304L is the AISI designation for this material. S30403 is the UNS number. Additionally, the British Standard (BS) designation is 304S12. This material is well established: the Further Reading section below cites a number of …
Differences Between AISI 304 and AISI304L Steel. The main difference between these two grades of steel lies in their respective carbon contents; AISI304 contains more carbon than its low-carbon counterpart AISI304L. The increased amount of carbon in regular ASI304 gives it greater strength and hardness than ASI304L but also makes it …
Brinell (HB) max. 500. >175. 40. 80-90. 150-180. END USES. AISI 304L steel is the same as AISI 304, however with less Carbon content, where the "L" in the name stands for "Low carbon". The lesser quantity of Carbon means this grade of stainless steel does not require annealing and therefore is widely used in very thick components (> 6 mm).
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.
