(PDF) Emphasis of Embrittlement Characteristics in 304L

Effect of Nitrogen on Hydrogen Embrittlement in AISI type 316, 321 and 347 A ustenitic Stainless Steel, Journal of Materials Scien ce, Volume 25, Number 5 , pp. 2532 - 2538 . Comparative Study on Hydrogen Embrittlement TP321 stainless steel is widely used in hydrogenation refining pipes owing to its excellent performance of creep stress resistance and high-temperature resistance. In this study, thermal simulation tests were carried out on the welding heat-affected zone (HAZ) of TP321 stainless steel at temperatures of 1300 °C, 1100 °C, and 850°C using a Gleeble 3800 testing machine.

HYDROGEN EMBRITTLEMENT OF ULTRAFINE-GRAINED

Hydrogen embrittlement of ultrafine-grained austenitic stainless steels 27 The second one, Cr-Ni-Mo stainless steel (AISI 316L-type), possesses stable austenitic structure due to rather high SFE [24]. The choice of these two steels gives the opportunity to compare the effect of SFE, i.e., stability of austenitic structure to martensitic Hydrogen Embrittlement - NACEHydrogen Embrittlement. This is a type of deterioration which can be linked to corrosion and corrosion-control processes. It involves the ingress of hydrogen into a component, an event that can seriously reduce the ductility and load-bearing capacity, cause cracking and catastrophic brittle failures at stresses below the yield stress of susceptible materials. 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 316L Stainless Steels Exposed

Jul 12, 2019 · The effect of hydrogen embrittlement on the stainless steel implied the ductility loss. Although the samples have been immersed at different immersion times starting from 10 minutes to one day, there was small difference on the ductility between the samples. Sample immersed for 10 minutes is the most ductile followed by one-hour immersion and Hydrogen embrittlement of austenitic stainless steels The contribution deals with the modeling of hydrogen embrittlement in AISI TYPE 316L solution-annealed austenitic stainless steel, to be used for the first wall of NET (Next European Torus). The mechanical behavior of the steel in the presence of hydrogen does not change from ductile to brittle in a macroscopic sense. NASA Technical Reports Server (NTRS)May 02, 2016 · Hydrogen Embrittlement Hydrogen embrittlement (HE) is a process resulting in a decrease in the fracture toughness or ductility of a metal due to the presence of atomic hydrogen. In addition to pure hydrogen gas as a direct source for the absorption of atomic hydrogen, the damaging effect can manifest itself from other hydrogen-containing gas species such as hydrogen sulfide (H2S), hydrogen NASA Technical Reports Server (NTRS)May 02, 2016 · Hydrogen Embrittlement Hydrogen embrittlement (HE) is a process resulting in a decrease in the fracture toughness or ductility of a metal due to the presence of atomic hydrogen.

At higher strain rates the ductility is substantially improved; this is interpreted as high velocity dislocations separating from hydrogen atmospheres [14].
