Alloy 405 is a 12% chromium stainless steel designed to be used in the as-welded condition. Unlike the other grades of 12% chromium stainless, 405 is not vulnerable to extensive hardening through air cooling from high temperatures. Applications that frequently use alloy 405 include, but are not limited to:

  • Steam nozzles
  • Partitions
  • Annealing boxes
  • Quenching racks
  • Fabrications that cannot be annealed after welding
