... (ASS), especially UNS S31603 with a minimum yield strength (YS) of 170 MPa (25 ksi), is frequently used for hydrogen applications due to its low susceptibility to HE compared with other ASSs. However, ASS cannot be used when high strength (YS > 500 MPa) is required. Nitrogen-strengthened (e.g. UNS...

... ABSTRACT In order to extend the range of alloy 955 (UNS N09955) applications, the manufacturing process of this alloy has been further optimized to increase its ductility, toughness and, more importantly, resistance to hydrogen embrittlement and still provide 827 MPa (120 ksi) as minimum yield...

... scenarios are computed. In all modeling cases fatigue fracture failure is defined at the middle of the crack front when either K1c (28 ksi in0.5, plain strain fracture toughness) or K1e (38 ksi in0.5, fracture toughness for surface crack) are exceeded. Stress Analysis To first understand the stress field...

When K was between 12 ksi· in (13MPa· m) and 36 ksi· in (40 MPa· m), FCGR of all specimens in sour water are higher than the mean + 2 SD (Standard Deviation...

... by UNS S41425, S41426 and S41427 with specified minimum yield strengths (SMYS) between 95 ksi (655 MPa) to 125 ksi (758 MPa).4 These grades show a good compromise between mechanical properties and corrosion resistance, and good sulfide stress cracking resistance. Super 13Cr are widely used in oil and gas...

... yield strength (YS) of 25 ksi (170 MPa), is frequently used for hydrogen applications due to its low susceptibility to HE, which is promoted by a high austenite stability. However, its use is limited when higher strength is required. Here, nitrogenstrengthened (UNS S20910), CrMnN and high interstitial...
