Alloy 330 Hex Cap Screws

Alloy 330 hex head cap screws are specifically designed for high temperature furnace applications such as vacuum furnaces, heat treating and brazing applications. 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. An austenitic nickel-chromium-iron-silicon alloy, 330 hex head cap screws also offer industry a low coefficient of expansion, excellent ductility, and high strength. Benefits & Corrosion Resistance Resistance to thermal shock from repeated quenching High level of resistance to oxidation and carburization Ability to handle thermal cycling Provides resistance to scale formation up to about 2000°F Good resistance to nitrogen-containing atmospheres where the oxygen content is low High nickel content of 34-37% provides high resistance to chloride stress corrosion cracking and embrittlement Applications for Alloy 330 Hex Head Cap Screws Alloy 330 hex head screws are often used in furnaces, thermal processing and heat treating applications. Gas turbine components and boiler fixtures used in power generation often use Alloy 330 hex head screws. Because of its resistance to nitrogen rich environments, alloy 330 hex head screws are used extensively for components handling cracked ammonia.
