Introduction to 405 Stainless Steel
General Properties
Alloy 405 is a 12% chromium stainless steel designed to be used in the as-welded condition. Unlike other grades of 12% chromium stainless steel, 405 is not vulnerable to extensive hardening through air cooling from high temperatures.
Specification: UNS S40500
Applications
- Steam nozzles
- Partitions
- Annealing boxes
- Quenching racks
- Fabrications that cannot be annealed after welding
Corrosion Resistance
Offers the same corrosion resistance as Type 410 steel, but with improved weldability characteristics.
Machinability
Type 405 can be easily machined due to its soft and ductile characteristics.
Weldability
Can be welded using shielded fusion and resistance techniques. Oxyacetylene welding is not recommended. Post-weld annealing will maximize ductility.
