An engineered high temperature resistant steelAlloy  330 Threaded Rod

  • Excellent high temperature stability and strength
  • Very oxidation and carburization resistant to 2100°F
  • Good resistance to thermal shock and quenching

Alloy 330 threaded rods 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 threaded rods 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 Threaded Rods

  • Alloy 330 threaded rods 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 threaded rods.
  • Because of its resistance to nitrogen rich environments, alloy 330 rods are used extensively for components handling cracked ammonia.
