1.4404 Stainless Steel heat treatment conditions

Heat Treatment Type Condition Temperature Range Cooling Method Purpose/Outcome
Solution Annealing Heating to dissolve carbides and homogenize the structure. 1020–1100°C (1870–2010°F) Rapid cooling (water or air) - Produces a single austenitic phase.
- Maximizes corrosion resistance.
- Improves ductility for forming/welding.
Stress Relieving Reduces internal stresses from machining, welding, or cold working. 250–400°C (480–750°F) Air cooling - Minimizes the risk of stress corrosion cracking.
- Does not significantly alter hardness.
Annealing (for softening) Softens the material for subsequent cold working or machining. 850–1000°C (1560–1830°F) Slow cooling (furnace) - Reduces hardness.
- Improves machinability.
- Not typically used for 1.4404 in critical applications.
