Martensitic precipitation / age-hardenable stainless cold rolled steel strip coil 630
Martensitic precipitation/age-hardenable stainless alloy offering high strength and hardness, excellent corrosion resistance,
and good fabricating characteristics.
Stainless Alloy 17-4PH is a chromium-copper precipitation hardening stainless steel that is used
for applications requiring high strength and a moderate level of corrosion resistance.
It is one of the most widely used precipitation hardening grades, as it has high strength hardness up to
about 572°F while demonstrating good corrosion resistance in all heat treated conditions.
17-4PH has adequate resistance to atmospheric corrosion or in diluted acid salts where its corrosion
resistance is equivalent to Alloy 304 or 430.
stainless 17-4PH can be heat treated to a variety of temperatures to develop a wide range of properties.
Its mechanical properties can be optimized with heat treatment where very high yield strength up to 180 ksi can be achieved.
17-4PH stainless should not be used at temperatures above 572°F or at very low temperatures.
