For example of a severe embrittlement measured by Jewett, the elongation at failure of 17-4PH precipitation hardened stainless steel was

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 traps in the outgassing model of a stainless

304 stainless steel. Hydrogen outgassing from stainless steel is widely known to be controlled by the diffusion of hydrogen atoms within the steel and their recombination into molecules at the surface.47 Less well known is the inuence of hydrogen traps, which are sites at which a hydrogen Technical Reference on Hydrogen Compatibility of stainless steel [5].

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

What is an Acid Embrittlement? - Definition from

Sep 24, 2013 41 stainless steel hydrogen embrittlementnbsp; 41 stainless steel hydrogen embrittlement#0183; 41 stainless steel hydrogen embrittlement#32;Acid embrittlement is a process in which brittleness is induced in metals, especially steel, when immersed in acidic solutions. Acids contain hydrogen, and when these metals are immersed in acids, they absorb hydrogen, becoming brittle, and can readily fracture when subjected to stress.
