However, to understand how welding parameters affect the thermal cycle and the material flow around the tool is essential to produce joints without defects. In this work, a numerical simulation of dissimilar joints of AISI 304L austenitic stainless steel with AISI 410S ferritic stainless steel using the FSW technique was performed.

In grade 304 stainless steel, the maximum carbon content is set at 0.08%, whereas grade 304L stainless steel has a maximum carbon content of 0.03%. This is why 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.

Corrosion Resistance. When it comes to corrosion resistance, both AISI 316L and 304L stainless steel offer superior protection against a wide range of corrosive agents. However, 316L offers better resistance than 304L in environments with higher chloride concentrations, such as marine and coastal applications.

The increase in hardness of AISI 304L after application of DCT cannot be linked to a more effective transformation of retained austenite into martensite [11,15,36] or by higher solution annealing temperature, because the control with a higher selected temperature (1080 °C) has lower hardness value compared to tested DCT1.

لذا در کاربردهایی که استیل های گرید 304 و 316 نیاز به جوشکاری دارند و یا در معرض دمای بیش از 450 درجه در حضور محیط خورنده قرار دارند، باید از گریدهای کربن پایین (AISI 304L, AISI 316L) استفاده کرد.

Type 304L Stainless Steel. Type 304L stainless steel is an extra-low carbon version of the 304 steel alloy. The lower carbon content in 304L minimizes deleterious or harmful carbide precipitation as a result of welding. 304L can, therefore, be used "as welded" in severe corrosion environments, and it eliminates the need for annealing.

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 …
