Sachiya Steel International is one of the Leading Manufacturer And Exporter of High Quality Super Duplex S32750 Socket Weld Fittings, where the corrosively of such solutions is affected by acidity and chloride content. In aqueous solutions containing hydrogen sulphide and chlorides, stress corrosion cracking can also occur on Super Duplex S32750 Forged Socket Weld Elbow Fittings at temperatures below 60 Degree C (140 Degree F). In direct contrast to the case with ordinary chloride – induced stress corrosion cracking, ferritic stainless steels such as Super Duplex S32760 Forged Socket Weld Tee Fittings are more sensitive to this type of stress corrosion cracking than austenitic steels.
In accordance with solution annealed and liquid quenched wrought Super Duplex S32750 Forged Socket Weld Cap Fittings are suitable for use at temperatures up to 450 Degree F (232 Degree C) in sour environments in oil and gas production, if the partial pressure of hydrogen sulphide does not exceed. Hydrogen Induced Stress Cracking (HISC) in Super Duplex S32760 Forged Socket Weld Coupling Fittings is an embrittlement phenomenon which may occur in catholically protected subsea steel constructions in the presence of high tensile stresses.
When connected to catholically protected carbon steels, Super Duplex S32750 Forged Socket Weld Cross Fittings will also be catholically protected even though this is not necessary. The low, ambient, and elevated temperature are mechanical properties of Super Duplex S32760 Forged Socket Weld Union Fittings.
