From the review it is understood that AISI 304L austenitic Stainless Steel is the best material where there is a problem of intergranular corrosion. Also it is one of the best materials frequently used in manufacturing non heat treatable components. Keywords: austenitic stainless steel; AISI 304L; welding. Received: . Accepted: .

A commercial AISI 304L austenitic stainless steel was tested to tensile. The chemical composition (mass %) of 304L as-received stainless steel (SS) used in this experiment, according to the specifications of ASTM SA-240, is shown in Table 1. The material was solution annealed at 1050°C and then water quenched.

Austenitic stainless steels 1.4301 (AISI 304) and 1.4307 (AISI 304L) are frequently investigated in this context: on the one hand, to compare them with existing materials or new alloys, intended for use in a hydrogen environment, and on the other hand, because of their relatively low cost, which is mandatory for applications on a massive scale.

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 …

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.

A popular AM steel is the AISI type 304L austenitic stainless steel (SS 304L). The tensile properties of this SS 304L made by direct energy deposition (DED) additive manufacturing from pre-alloyed stainless steel 304L powder are discussed in this section and compared with conventionally made tensile specimens. In Table 3.9 a summary of the ...

G. EGELS, M. BUSSMANN, S. BENITO, and S. WEBER. In this study, the deformation-induced a-martensite formation in AISI 304L steel was investigated in the temperature range between 75 C and 196 C in the light of the temperature-dependence of hydrogen embrittlement phenomena. For this purpose, tensile tests with in-situ and ex-situ …

Stainless steel 304 has good resistance to oxidation in intermittent service up to 870°C and in continuous service to 925°C. However, continuous use at 425-860°C is not recommended if corrosion resistance in water is required. In this instance 304L is recommended due to its resistance to carbide precipitation. Where high strength is …

available SS 304L austenitic stainless steel with follow-ing chemical composition in wt pct: 0.03 pct C, 1.065 pct Mn, 0.34 pct Si, 18.27 pct Cr, 8.00 pct Ni, 0.31 pct Cu, 0.320 pct Mo, 0.10 pct Co, 0.05 pct S, and 0.027 pct P. The material was solution annealed at 1050 C for 1 hours and then quenched to remove any remnant martensitic phase.

An AISI 304L stainless steel was oxidised in a TGA instrument at temperatures ranging from 800 to 1,200 °C and for up to 3 h. The measured weight gains were fitted starting from the Wagner model, taking into account both a linear and a parabolic behaviour. Rate constants and activation energies were calculated. The fraction of …

The effect of low-energy Ar+ ion irradiation on the work function of stainless steel AISI 304L (SS-304L) was studied by varying energy and fluence of Ar+ ion. The irradiation of Ar+ ions on stainless steel creates several vacancies in the target material which resulted a change in work function. The retarding field diode method was used for …
