General Properties of 17-4PH SS, Alloy 17-4 PH, Stainless Steel 17-4 PH

SAE type 630 stainless steel (more commonly known as 17-4 PH; also known as UNS 17400) is a grade of martensitic precipitation hardened stainless steel. It contains approximately 15–17.5% (17) chromium and 3–5% (4) nickel, as well as 3–5% copper.

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

 

Here are some benefits of 17-4 PH round bars. Listed below:

  • High tensile strength and toughness
  • Excellent corrosion resistance
  • It is best suited for forging and welding
  • Machinability operations
  • Oxidation resistance
  • Have a good resistance to sulphide stress cracking

Standards of SS 17-4 PH / UNS S17400 :

  • ASTM/ASME: UNS S17400
  • EURONORM: X5CrNiCuNb16.4
  • AFNOR: Z6CNU17-04
  • DIN: 1.4542
  • S17400
  • AISI 630
  • NACE MR 0175
  • ASTM A484/ A564
  • AMS 2303/5643
  • ASME SA564
  • 4542
  • X5CrNiCuNb16-4

 

Properties of SS 17-4 PH / UNS S17400 :

  • Alloy 17-4 PH is a martensitic stainless steel having Cu and Nb/Cb in addition.
  • A grade is its high strength.
  • Hardness up to 300 degrees Celsius.
  • Corrosion resistance.
  • Optimized with heat treatment.
  • High yield strength up to 160-190 ksi.

 

Corrosion Resistance of SS 17-4 PH / UNS S17400 :

  • 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.

 

Weldability of SS 17-4 PH / UNS S17400 :

  • Successfully welded by most common fusion and resistance methods.
  • Should not be joined by oxyacetylene welding.
  • Generally no pre-heating required.
  • Inter-pass temperature must be limited to 248°F.
  • Better toughness is obtained in the weld after a complete heat treatment. 

 

Processing – Hot Forming of SS 17-4 PH / UNS S17400 :

  • To forge, heat uniformly to 2150 / 2200°F and hold for half hour per inch.
  • Preferred temperature range for hot forming is at 650-900°F, while the steel is still austenitic.
  • To ensure the best condition for the hardening operations, the forgings must be re-heat treated at 1875-1925°F.
  • Cool forgings to below 90°F to ensure grain refinement.

 

Processing – Cold Forming of SS 17-4 PH / UNS S17400 :

  • Alloy 17-4 is limited to mild operations since in the annealed (solution treated) condition the material is hard.
  • For severe cold working the material should be heat treated to condition H1150. This will help prevent possible cracking.
  • Bend radius in excess of 7T is often required.
  • To improve stress corrosion resistance after cold forming, re-aging at the precipitation-hardening temperature is recommended.

 

Machinability of SS 17-4 PH / UNS S17400 :

  • Can be machined in both solution-treated and precipitation-hardening conditions.
  • Machining conditions may vary with hardness of material.
  • High-speed tools or preferably carbide tools with standard lubrication are normally used.
