Material Description
17-4PH Stainless Steel (Type 630) is a chromium-copper precipitation hardening stainless steel used for applications requiring high strength and moderate corrosion resistance. High strength is maintained to approximately 600°F (316°C).
General Properties

Alloy 17-4 PH is a precipitation hardening martensitic stainless steel with Cu and Nb/Cb additions. The grade combines high strength, hardness (up to 572°F / 300°C), and corrosion resistance.

Mechanical properties can be optimized with heat treatment. Very high yield strength up to 1100-1300 MPa (160-190 ksi) can be achieved.

The grade should not be used at temperatures above 572°F (300°C) or at very low temperatures. It has adequate resistance to atmospheric corrosion or in diluted acids or salts where its corrosion resistance is equivalent to Alloy 304 or 430.

Applications
  • Offshore (foils, helicopter deck platforms, etc.)
  • Food industry
  • Pulp and paper industry
  • Aerospace (turbine blades, etc.)
  • Mechanical components
  • Nuclear waste casks
Standards
  • ASTM A693 grade 630 (AMS 5604B) UNS S17400
  • EURONORM 1.4542 X5CrNiCuNb 16-4
  • AFNOR Z5 CNU 17-4PH
  • DIN 1.4542
Corrosion Resistance

Alloy 17-4 PH withstands corrosive attacks better than any of the standard hardenable stainless steels and is comparable to Alloy 304 in most media.

If there are potential risks of stress corrosion cracking, the higher aging temperatures then must be selected over 1022°F (550°C), preferably 1094°F (590°C). 1022°F (550°C) is the optimum tempering temperature in chloride media.

1094°F (590°C) is the optimum tempering temperature in H2S media. The alloy is subject to crevice or pitting attack if exposed to stagnant seawater for any length of time.

It is corrosion resistant in some chemical, petroleum, paper, dairy and food processing industries (equivalent to 304L grade).

Heat Treatment

Solution treatment (Condition A) - Grade 630 stainless steels are heated at 1040°C for 0.5 h, then air-cooled to 30°C. Small sections of these grades can be oil quenched.

Hardening - Grade 630 stainless steels are age-hardened at low temperatures to achieve the required mechanical properties. During the process, superficial discoloration occurs followed by shrinkage at 0.10% for condition H1150, and 0.05% for condition H900.

Welding & Machining

Welding: Grade 630 stainless steels can be welded using all conventional methods, and they do not require pre-heating. Care should be taken in designing and welding of high strength steels to prevent weldment stresses.

Machining: Grade 630 stainless steels can be machined in their solution-treated condition. They have machining rates similar to that of grade 304 steels.

Applications
  • Engine components
  • High strength and boat propeller shafts
  • Plastic moulding dies
  • Valves and gears
