Incoloy Screw

TorqBolt is specialised in manufacturing Incoloy Screws. Nickel alloy screws with a base of austenitic chromium and nickel also known by the trade name Nickel-Chromium Alloys. More preferred over Duplex Screws and Super Duplex Screws since It has high corrosion resistance to acids and alkalis with high mechanical properties and ductility subjected to high pressure and heats both. Inconel Screws are difficult to machine and hot roll threading is done to ensure 100% thread strength. It forms a passivation oxide layer once heated and hence used at wide range of elevated temperatures unlike Copper Nickel Screws and Silicon Bronze Screws.
Applications: Inconel Screws are used for high-pressure vessels, heat exchangers, nuclear reactors etc.
