    Apr 01, 2019 · 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.

    The crack growth rate in an unstable austenitic stainless steel (AISI 301) is all the more important since the hydrogen content is high, moreover, the stress crack initiation is lower than for stable austenitic stainless steel (AISI 310S).

    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.

  28. What is Hydrogen Embrittlement and How is it Prevented?,

    Hydrogen embrittlement results from the simultaneous codeposition of the primary metal and hydrogen on the surface of the work piece (cathode). The hydrogen is available from the water in aqueous plating bath chemistries and is also exposed at the surface of the work piece during the acid pickling steps of the pretreatment process.

    Hydrogen embrittlement occurs in a number of forms but the common features are an applied tensile stress and hydrogen dissolved in the metal. Examples of hydrogen embrittlement are cracking of weldments or hardened steels when exposed to hydrogen-rich environments. Hydrogen embrittlement does not affect all materials equally.
