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
