Precipitation Hardening
Precipitation hardening stainless steels, like the martensitic
types, can be strengthened (i.e., hardened) by heat
treatment. The mechanism is metallurgically different
from the process in the martensitic types. This means
that either martensitic or austenitic precipitation
hardening structures can be produced. These stainless
steels combine high strength and hardness with corrosion
resistance which is superior to that of the martensitic
chromium stainless steels.
