347 Stainless Steel Bar

347 stainless is an austenitic stainless steel offering an excellent resistance to inter-granular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800 to 1500O F. Alloy 347 alloyed with columbium-tantalum (referred to as niobium) allows good mechanical properties at high temperatures.

Applications:

  • High temperature gaskets
  • Rocket engine parts
  • Expansion joints
  • Aircraft collector rings
  • Exhaust manifolds
  • Chemical production equipment
