What is embrittlement in stainless steel?

The phenomenon of embrittlement in austenitic stainless steel welds exposed to high temperature is accelerated by the presence of delta ferrite.See all results for this questionWhat is Delta ferrite embrittlement?Weld metal containing delta ferrite will also be susceptible to '475°C embrittlement'. This phenomenon is observed when stainless steels are heated into the range 400 - 550°C (although the effect is most pronounced at 475°C) and a dramatic fall in toughness is observed after extended exposure.See all results for this questionTritium embrittlement of austenitic stainless-steel tubing austenitic stainless steel hydrogen embrittlementThe deleterious effects of hydrogen on the mechanical properties of austenitic stainless steels are frequently magnified by the presence of helium. Helium can be introduced into steel by either tritium absorption, diffusion and decay (tritium-tricked) or by implantation during irradiation.

hydrogen-assisted fracture in austenitic stainless steels, martensite, in both sensitized and nonsensitized microstructures, is associated with lower resistance to hydrogen embrittlement. The trend for Fe-Cr-Ni stainless steels (300-series alloys) is that higher nickel concentrationTechnical Reference on Hydrogen Compatibility of compared to more highly alloyed stainless steels such as type 316. Austenitic stainless steels with low stacking fault energy are more susceptible to hydrogen embrittlement, a feature generally attributed to non-uniform plastic deformation [4, 5]. Warm-working type 304 stainlessStudy on Effect of Failure Modes in Hydrogen called as Hydrogen embrittlement. Hydrogen embrittlement is a mechanism and is an important subject for many applications. Austenitic stainless steel is most widely used material in automotive as well as household appliances, because of its low cost, price stable and corrosion-resistant steel. The austenitic
