Precipitation hardening stainless steels have been formulated so that they can be supplied in a solution treated condition, (in which they are machineable) and can be hardened, after fabrication, in a single low temperature "ageing" process.
- Moderate to good corrosion resistance
- Very high strength
- Good weldability
- Shafts for pumps and valves
