Sachiya Steel International Is One Of The Leading Manufacturer And Exporter Of High Quality SMO 254 Nipple, which is tested in sodium chloride solution in the presence of thiosulfate. It shows susceptibility to IGSCC, comparable to that of our SMO 254 Hexagon Reducing Nipple, only in sodium chloride and a much lower susceptibility in sulphuric acid and sodium chloride. It must be notice that the sensitization treatment provoked a noticeable modification on the mechanical characteristics of SMO 254 Hexagon Nipple.

The percentage elongation to fracture of the solubilized and sensitized our SMO 254 One End Threaded Nipple in different solutions is compared. In any case the ductility of sensitized SMO 254 Both End Threaded Nipple was hardly decreased. In sodium chloride in which no SCC was observed the percentage elongation to fracture decreased from 56.5 % in the solubilized to 32.9 % in the sensitized of our SMO 254 Concentric Swaged Nipple.
SMO 254 Eccentric Swaged Nipple showed a high ultimate strength resistance, suggesting a hardening due to the precipitation of new phases at grain boundaries. In fact, it is known that the addition of thiosulfate to sodium chloride solutions in our SMO 254 Hex Nipple stimulates the pitting corrosion and provokes SCC on different alloys. The addition of thiosulfate to sodium chloride shifted the pitting potential of sensitized Alloy 254 Hexagon Reducing Nipple towards negative potentials. The polarization curves showed that our Alloy 254 Hexagon Nipple was active in this solution.
