Product Description
630 (1.4542) Stainless Steel 17-4PH Bar

17-4 Precipitation Hardening (Type 630) is a chromium-copper precipitation hardening stainless steel designed for applications requiring high strength and moderate corrosion resistance. This alloy maintains high strength up to approximately 600°F (316°C).

General Properties

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

Mechanical properties can be optimized through heat treatment, achieving very high yield strength up to 1100-1300 MPa (160-190 ksi). The grade should not be used above 572°F (300°C) or at very low temperatures.

Applications
  • Offshore applications (foils, helicopter deck platforms)
  • Food processing industry
  • Pulp and paper industry
  • Aerospace components (turbine blades)
  • Mechanical components
  • Nuclear waste casks
Standards Compliance
  • 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 provides superior corrosion resistance compared to standard hardenable stainless steels and is comparable to Alloy 304 in most media. For applications with stress corrosion cracking risks, aging temperatures above 1022°F (550°C) are recommended.

The alloy demonstrates excellent resistance in chemical, petroleum, paper, dairy, and food processing industries, equivalent to 304L grade performance.

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: Performed at low temperatures to achieve required mechanical properties with minimal distortion (0.10% shrinkage for H1150, 0.05% for H900).

Alternative Grade Comparison
Alternative Grade Selection Considerations
431 Higher toughness than 17-4PH, better availability in some sizes
416 Free-machining martensitic stainless steel, better for repetition machining, lower cost
316 Higher corrosion resistance for severe environments, but with much lower strength
2205 Much better corrosion resistance with lower strength (not as low as 316)
Processing Characteristics

Welding: Grade 630 can be welded using all conventional methods without pre-heating requirements.

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

Typical Applications
  • Engine components
  • High-strength boat propeller shafts
  • Plastic molding dies
  • Valves and gears
  • Aerospace turbine blades
  • Nuclear waste containment
