17-4ph 900 Stainless Steel Sheet/Plate

Alloy 17-4 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. Alloy 17-4 has adequate resistance to atmospheric corrosion or in diluted acid salts where its corrosion resistance is equivalent to Alloy 304 or 430. Alloy 17-4 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. Alloy 17-4 should not be used at temperatures above 572°F or at very low temperatures.

Applications:

  • Aircraft
  • Nuclear waste casks
  • Paper mills
  • Oil fields
  • Mechanical components
  • Chemical process components
  • Food industry
  • Aerospace

Corrosion Resistance:

  • Withstands corrosive attacks better than any of the standard hardenable stainless steels.
  • Comparable to Alloy 304 in most media.
  • Corrosion resistant in some chemical, petroleum, dairy, and food process industries.
  • Subject to crevice or pitting attack if exposed to stagnant sea water for any length of time.
