A nanotwinned austenite stainless steel with high hydrogen

Jun 05, 2019 41 stainless steel hydrogen embrittlementnbsp; 41 stainless steel hydrogen embrittlement#0183; 41 stainless steel hydrogen embrittlement#32;1. Introduction. Austenitic stainless steels (ASSs) are usually used for components of hydrogen generator, storage and transportation systems [].However, they can also suffer from hydrogen embrittlement (HE) when they were hydrogen charged cathodically or thermally [, , , , , , , ].Meanwhile, it is well known that ASSs possess a relatively low yield strength.

Hydrogen Embrittlement Of Austenitic Stainless Steel

Abstract. Type 310 stainless steel in thin sections was embrittled by hydrogen. The temperature and strain rate dependence of this embrittlement was almost analogous to that well-established for hydrogenated body-centered cubic (b.c.c.) metals, differing only in that at low temperatures and relatively high strain rates complete recovery in ductility was not achieved.

Hydrogen Embrittlement of Steel - Industrial Metallurgists

Abstract:This article discusses hydrogen embrittlement of carbon steel. This includes a discussion of the mechanism by which a steel becomes embrittled by hydrgogen, circumstances that lead to embrittlement, the effects of embrittlement on steel behavior, how to prevent the embrittlement, and tests for evaluating whether a steel has been embrittled.

Hydrogen embrittlement of austenitic stainless steels

In Type 304L stainless steel and Tenelon ductility losses are a maximum around 200 to 273/sup 0/K; Type 310 stainless steel is not embrittled at this hydrogen concentration.

Technical Reference on Hydrogen Compatibility of

Annealed type 304 stainless steel is susceptible to hydrogen embrittlement in tension, Table 3.1.1.1. The reduction in area (RA) of annealed type 304 stainless steel with either internal or external hydrogen can be as low as 30% compared to 75-80% for material in the absence of hydrogen. Technical Reference on Hydrogen Compatibility of stainless steel [5]. The high-nickel and chromium content of the A-286 family of alloys implies high stacking fault energy [6], a characteristic associated with uniform plastic deformation and consequently resistance to hydrogen embrittlement in austenitic stainless steels [7, 8]. The coherent interface

The behaviour of 316L stainless steel in hydrogen

Hydrogen embrittlement of 316L type austenitic stainless steel has been studied by charging thin tensile specimens (0.2 mm thick) with hydrogen through cathodic polarization. The effects of hydrogen on the phase transition and the relative role of the metallurgical variables is discussed. Room temperature cathodic charging of unstressed specimens produces intergranular and secondary Hydrogen Related Brittle Cracking of Metastable Type- Keywords:Meta-stable austenitic stainless steel, hydrogen induced brittle fracture, strain in-duced martensite, gliding dislocation Introduction Meta-stable austenitic stainless steels are known to be susceptible to hydrogen embrittlement. Many researchers reported that strain-induced martensite suffered hydrogen embrittlement [1, 2].
