Ninthore Overseas is one of the Leading Manufacturer And Exporter Of High Quality Incoloy 330 Round Bars, which has oxidation resistance and has excellent weldability and braze – ability. Typical applications of Incoloy 330 Round Bars would be heat exchangers, radiant tubes, gas turbines, salt pots and perlite processing. The 35 % nickel content of SS 330 Square Bars is considered the optimal figure for carburization resistance and it is highly resistant to thermal shock. With proper practices, Ra 330 Flat Bars can be satisfactorily machined. Incoloy 330 Threaded Bars is often the alloy of choice for retorts, fixturing, muffles and baskets.

Incoloy 330 Round Bars

Also capability to prevent formation of oxidation layer at high temperature makes welding of SS 330 Hollow Bars easier in industry grade applications. When buying a heat resistant alloy, insist on quality, insist it is Ra 330 Hexagonal Bars, where its oxidation resistance is enhanced by the silicon content. The microstructure of Incoloy 330 Triangular Bars maintains its stability even after being exposed to high temperatures for long durations.

The strength and oxidation resistance of SS 330 Bars at high temperatures make it a useful material for industrial heating furnaces. Ra 330 Rods is ideally suited for demanding, high – temperature, high – pressure applications such as chemical and petrochemical processing, ore processing, power generation and thermal processing. Alloy 330 Round Bars has good strength at high temperatures and excellent resistance to carburizing and oxidizing atmospheres.
