... on the critical stress intensity factor for sulfide stress cracking (K ISSC ). A common Cr-Mo high strength OCTG steel alloyed with three different Nb contents ranging from 300 to 1000 ppm is used. It was found that Nb addition allows the use of higher strength material without compromising the resistance...

... Abstract ATI has developed ATI 642 ™† alloy, a new Ni-Cr-Mo corrosion-resistant alloy that displays significant resistance to sensitization from the effects of hot-clad bonding and welding operations. The new alloy is unique because of its substantial Fe content, which gives it a significant...

... content, UNS N08825 shows an outstanding resistance to stress corrosion cracking in aqueous and acidic chloride-containing solutions. However, the molybdenum content of 2.5 to 3.5 wt.% limits its resistance to pitting and crevice corrosion in highly concentrated chloride-containing environments...
