Gas turbine components and boiler fixtures used in power generation often use Alloy 330 socket head screws.Alloy 330 socket head cap screws are often used in furnaces, thermal processing and heat treating applications.High nickel content of 34-37% provides high resistance to chloride stress corrosion cracking and embrittlementĪpplications for Alloy 330 Socket Head Cap Screws.Good resistance to nitrogen-containing atmospheres where the oxygen content is low.Provides resistance to scale formation up to about 2000☏.High level of resistance to oxidation and carburization.Resistance to thermal shock from repeated quenching.

An austenitic nickel-chromium-iron-silicon alloy, 330 socket head cap screws also offer industry a low coefficient of expansion, excellent ductility, and high strength. The most prized trait of alloy 330 is its ability perform under cyclic conditions of temperature extremes from heating and cooling as well as in alternate carburizing and oxidizing atmospheres. Alloy 330 socket head cap screw features and benefitsĪlloy 330 socket head cap screws are specifically designed for high temperature furnace applications such as vacuum furnaces, heat treating and brazing applications.Chemistry and specifications of alloy 330.
