Material Description
17-4PH (Type 630) is a chromium-copper precipitation hardening martensitic stainless steel with Cu and Nb/Cb additions. It combines high strength, hardness (up to 572°F / 300°C), and corrosion resistance equivalent to Alloy 304 or 430 in most media.
Applications
  • Offshore (foils, helicopter deck platforms)
  • Food industry
  • Pulp and paper industry
  • Aerospace (turbine blades)
  • Mechanical components
  • Nuclear waste casks

Alternative Grade Comparison
Alternative GradeReason for Choosing 17-4PH
431431 has higher toughness but 17-4PH offers better strength
416416 is free-machining but 17-4PH provides superior strength
316316 has higher corrosion resistance but much lower strength
22052205 has better corrosion resistance with lower strength
Heat Treatment
Solution treatment (Condition A): Heated at 1040°C for 0.5 h, then air-cooled to 30°C. Small sections can be oil quenched.

Processing Characteristics
Welding: Can be welded using all conventional methods without pre-heating. Care should be taken to prevent weldment stresses.
Machining: Can be machined in solution-treated condition with machining rates similar to grade 304 steels.
Product Applications
  • Engine components
  • High strength and boat propeller shafts
  • Plastic moulding dies
  • Valves and gears
