- Good resistance to thermal shock and quenching
- Alloy 330 chemistry and specifications
- Strength and mechanical properties
- ASTM F2281 specification for Alloy 330
- Alloy 330 Datasheet
Alloy 330 studs 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 studs 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 Studs
- Alloy 330 studs 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 studs.
- Because of its resistance to nitrogen rich environments, alloy 330 studs are used extensively for components handling cracked ammonia.
