Precipitation Age Hardenable Stainless Cold Rolled Steel Strip SUS630 17-4PH Coil
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.
