Ninthore Overseas is one of the Leading Manufacturer And Exporter Of High Quality Incoloy 330 Pipe Fittings And Other Incoloy Products to the clients, which is extensively used in high temperature environments where resistance to the combined effects of thermal cycling and carburization is necessary. Incoloy 330 Compression Pipe Fittings is a heat and corrosion resisting stainless steel alloy with good corrosion resistance and ductility and an exceptional combination of strength and resistance to carburization, oxidation, and thermal shock. During fabrication, our SS 330 Compression Pipe Fittings should not be pre – heated, inter – pass temperature should be kept low, and reinforced bead contours should be used.
