Comparison of hydrogen gas embrittlement of austenitic

Abstract Hydrogen-induced slow crack growth (SCG) was compared in austenitic and ferritic stainless steels at 0 to 125 °Cand 11 to 216 kPa of hydrogen gas. No SCG was observed for AISI 310, while AISI 301 was more susceptible to hydrogen embrittlement and had higher cracking velocity than AL 29-4-2 under the same test conditions.

Austenitic stainless steels (ASSs), especially stable ASSs in which martensite transformation can hardly occur during deformation due to their high austenite mechanical stability, are usually used for hydrogen components because of their high hydrogen embrittlement (HE) resistance [, , ].However, their low strength and high nickel content make the components bulky Hydrogen Compatibility of Materials - Energy.gov7 Example:hydrogen embrittlement in diaphragm compressor High-volume, two-stage diaphragm compressor Maximum output pressure:70 MPa Used in hydrogen containing environments Compressor adapted for high-purity hydrogen system Second stage

Hydrogen Embrittlement In Metal Finishing Mid Atlantic

Dec 16, 2016 · Other metals such as stainless steel, nickel and copper alloys are also susceptible to the effects of hydrogen. Example of hydrogen embrittlement on a part Hydrogen Embrittlement has been an issue for the metal finishing industry since the beginning of the industrial revolution and was first described in 1875. Hydrogen Embrittlement in FastenersHydrogen Embrittlement (HE) a permanent loss of ductility in a metal or alloy caused b y hydrogen in combination with stress, either externally applied or internal residual stress [1]. Generally, hydrogen embrittlement is classified under two broad categories based on the Hydrogen Embrittlement of Steel - Industrial MetallurgistsAbstract: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 is a []

Hydrogen Permeation Behavior of Stainless Steels

Key words:Hydrogen permeation, stainless steel, nitride phase, nitrogen-plasma. 1. Introduction High-strength steel and various structural metals such as Al, Ti and Zr are likely to undergo hydrogen embrittlement due to penetration by hydrogen in the environment in which it Hydrogen compatibility handbook for stainless steels @article{osti_5906050, title = {Hydrogen compatibility handbook for stainless steels}, author = {Caskey, Jr, G R}, abstractNote = {This handbook compiles data on the effects of hydrogen on the mechanical properties of stainless steels and discusses this data within the context of current understanding of hydrogen compatibility of metals. . All of the tabulated data derives from continuing On the Effects of Martensite in Hydrogen Embrittlement This, however, leads to hydrogen embrittlement (HE), limiting the application of austenitic stainless steel such as AISI 301, 304, and 316 in hydrogen-containing environments since SIM acts as a

Technical Reference on Hydrogen Compatibility of

resistance to hydrogen embrittlement in austenitic stainless steels [7, 8]. The coherent interface of the g precipitates in A-286 and JBK-75, on the hand, tends to enable non-uniform plastic deformation, a feature in austenitic steels that is often used to explain comparatively poor resistance to hydrogen embrittlement [6, 9]. Understanding and mitigating hydrogen embrittlement of Feb 06, 2018 · Metastable austenitic stainless steels such as types 301, 304 and 316 are expected to be much more vulnerable to hydrogen embrittlement when hydrogen charged [22, 23, 45, 46, 68, 76, 180, 192] or in a hydrogen gas environment [57, 66, 157, 160, 187, 198]. What is Hydrogen Embrittlement and How is it Prevented? As such, hydrogen embrittlement is a concern even in electroless plating processes. It is readily removed from the metal lattice by baking the product immediately after plating. The requirement for baking is a time-at-temperature cycle that is generally specified on the part print or

Galvanic Coupling of Some Stressed Stainless Steels to

Stainless steels, Type 301 half hard and Type 301 full hard, have been found susceptible to failure by hydrogen embrittlement when stressed as low as 40 percent of their yield strength and cathodically charged above 1 A/cm 2 by galvanic coupling to a dissimilar metal in four years of exposure at six underground test sites. However, stainless steels Type 304 and alloys 26Cr-1Mo and 26Cr-6.5Ni
