TL;DR: In this paper, a low-alloy steel pipe for oil well use is presented, which has a composition containing 0.15 to 0.30% C and 0.05 to 1.0% Si, 0.10 to 1 0% Mn, =20 μm <=10 pieces/100 mm2.
Abstract: PROBLEM TO BE SOLVED: To stably produce a high strength low alloy steel pipe for oil well use excellent in sulfide stress corrosion cracking resistance at a low cost. SOLUTION: (1) This steel for oil well use has a composition containing 0.15 to 0.30% C, 0.05 to 1.0% Si, 0.10 to 1.0% Mn, =20 μm<=10 pieces/100 mm2...(b). (2) In the method for producing a steel pipe for oil well use, at the time of producing a steel pipe using the above steel, after tube making by hot working, without cooling, the pipe is directly quenched as it is, or is quenched after holding at a temperature of the Ac3 transformation point or more and is next tempered at the Ac1 transformation point or less.

TL;DR: The fracture ductility of anodic films was measured for Alloy 800 at 300°C in a neutral crevice solution with and without lead contamination as mentioned in this paper, and it was found that the sensitivity of SCC resistance to lead contamination increased with an increase in the impact of lead contamination on the film rupture ductility.

TL;DR: In this paper, the effects of applied stress and microstructure on sulfide stress cracking resistance of pipeline steels subject to hydrogen sulfide were investigated by the single-edge notched tensile method using a microalloyed steel and a non-microalloying steel.
Abstract: Effects of applied stress and microstructure on sulfide stress cracking resistance of pipeline steels subject to hydrogen sulfide were investigated by the single-edge notched tensile method using a microalloyed steel and a non-microalloyed steel. The failure time increased with the decreasing applied stress, and finally the threshold stress intensity factor was calculated for acicular ferrite (AF) and ferrite-pearlite (FP) in these two steels. The strength was not the dominant factor for the SSC, and aged microalloyed AF had the best SSC resistance in coincidence with the highest strength. The SSC resistance in sort ascending was non-microalloyed AF, non-microalloyed FP, microalloyed FP, microalloyed AF and aged microalloyed AF. The SSC was explained from hydrogen penetration and microstructural characteristic. The localized hydrogen concentration was enhanced by applied stress. The higher the applied stress, the more easily the SSC occurred. Carbonitrides and pinned dislocations contributed in better SSC resistance.
