Material Properties

17-4PH is a precipitation hardening martensitic stainless steel with copper and niobium additions. It combines high strength, hardness (up to 572°F/300°C), and corrosion resistance equivalent to Alloy 304 or 430 in most media.

Very high yield strength up to 1100-1300 MPa (160-190 ksi) can be achieved through heat treatment optimization.

Applications
  • Offshore applications (foils, helicopter deck platforms)
  • Food processing industry
  • Pulp and paper industry
  • Aerospace components (turbine blades)
  • Mechanical components
  • Nuclear waste casks
  • Engine components
  • Boat propeller shafts
  • Plastic molding dies
  • Valves and gears

Heat Treatment

Solution Treatment (Condition A): Heat to 1040°C for 0.5 hours, then air-cool to 30°C. Small sections may be oil quenched.

Age Hardening: Various temperature and time combinations achieve specific mechanical properties:

Processing Characteristics

Welding: Can be welded using all conventional methods without pre-heating. Design carefully to prevent weldment stresses.

Machining: Best machined in solution-treated condition with rates similar to grade 304 stainless steel.
