Steel Company stocks a complete line of 17-4PH stainless
steel plate for applications in offshore, food, pulp
and paper, aerospace, and mechanical components and
nuclear waste casks.
Precipitation hardening stainless steel
plate, 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. All precipitation
hardening stainless steel plate contains a relatively
high chromium content. Most applications of precipitation
hardening stainless steel plate are for corrosion resistance
or oxidation resistance and retention of strength at
elevated temperatures.
