Inconel is a family superalloys whose basic chemical composition consists of nickel and chromium. Inconel grade alloys have an austenite microstructure.One of the best features of the Inconel Socket Head Cap Screws are its superior resistance to oxidation corrosion. On account of a high content of chromium in the Inconel alloy, there is a passivate oxide layer formed on the surface of these fittings.

This passivate oxide layer protects the  Inconel Nuts And Bolts from oxidative corrosion, otherwise known as rusting. Since Inconel alloy has good resistance to oxidation corrosion, the fasteners manufactured from this alloy are well suited for applications where the equipment’s are subjected to extreme heat and pressure environments.

At elevated temperatures, Inconel maintains its high tensile strength, thereby proving to be attractive for applications at elevated temperatures where metals like steel and aluminium would succumb to creep. The high tensile strength of the Inconel Nuts And Bolts is attributed to precipitation hardening or solid solution strengthening processes. When trace amounts of niobium is added to in combination with nickel to the Inconel Exhaust Bolts, there is a formation of  an intermetallic compound known as gamma double prime.
