Description

These stainless alloys are austenitic chromium steels containing columbium. The addition of columbium produces a stabilized type of stainless that eliminates carbide precipitation, and consequently, intergranular corrosion. They are recommended for parts fabricated by welding, that cannot be subsequently annealed. They also are used for parts, that can be intermittently heated and cooled to temperatures between 800° and 1600° F.

Typical Applications

  • High temperature chemical process
  • Heat exchanger tubes
  • Refineries
  • High temperature steam service
