WebSince the three main classes of stainless steels are named in accordance with their predominant metallurgical phases, e.g. ferritic, austenitic and martensitic, it seems advisable to explain these phases before discussing each stainless steel class in further detail. An elementary knowledge of solid solutions in metals will also lead to a ... WebMar 27, 2024 · This is due to the precipitation of Cr 2 N nitride instead of Cr 23 C 6 carbide. Low-carbon austenitic stainless steel contains 0.03% maximum carbon in order to minimise the risk of sensitisation during welding or heat treatments. The yield strength of low carbon grades is lower than that of standard grades.
WebUse ultra-low carbon austenitic stainless steels, such as 304L and 316L, can reduce the formation of chromium carbide and reduce the probability of chromium-depleted envelope.
