SAE steel grades. The SAE steel grades system is a standard alloy numbering system (SAE J1086 - Numbering Metals and Alloys) for steel grades maintained by SAE International . In the 1930s and 1940s, the American Iron and Steel Institute (AISI) and SAE were both involved in efforts to standardize such a numbering system for steels.
In the current study, dynamic strain ageing (DSA) phenomena in 316L austenitic stainless steel was investigated under as-received and as-welded conditions.

Fig. 3 (a and b) show the morphology and chemical composition of the duplex sample, respectively; these results indicate that the modified layer is composed of a multilayer coating and a nitrided layer. The CrN/CrTiAlSiN/WCrTiAlN multilayers coating (Fig. 3 a) consisted of a 0.3 μm CrN bottom-layer, a 1.6 μm CrTiAlSiN interlayer, and a …
The ion nitriding behavior of AISI 316L austenite stainless steel was investigated at different nitriding times (2 h, 4 h, and 9 h) and temperatures (450 °C, 500 °C, and 550 °C). The structural characterization has been assessed by several considerations which can be listed: (i) the evaluation of phase distribution through Rietveld analysis of X …
It is evident that in the case of AISI 316L the material displays a non-Masing behaviour given that the tensile branches of the "stabilised" hysteresis loop do not overlap. Moreover, in a material with Masing behaviour the cyclic curve is obtained by simply translating the monotonic curve upward or downward, which clearly is not the case for the …
