Описание продукта
17-4PH Stainless Steel Round 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/columbium 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 alloy should not be used above 572°F (300°C) or at very low temperatures. It provides adequate resistance to atmospheric corrosion and diluted acids or salts, with corrosion resistance equivalent to Alloy 304 or 430.

Applications & Standards
Applications:
  • Offshore equipment (foils, helicopter deck platforms)
  • Food processing industry
  • Pulp and paper industry
  • Aerospace components (turbine blades)
  • 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 standard hardenable stainless steels and is comparable to Alloy 304 in most media. For stress corrosion cracking risks, higher aging temperatures above 1022°F (550°C), preferably 1094°F (590°C), should be selected.

The alloy may experience crevice or pitting attack in stagnant seawater but provides excellent corrosion resistance in chemical, petroleum, paper, dairy, and food processing industries (equivalent to 304L grade).

Alternative Grades Comparison

Grade Reasons for choosing 17/4PH (630)
431 431 has 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 to resist more severe environments, but with much lower strength than 17/4PH.
2205 Much better corrosion resistance than 17/4PH, with lower strength (but not as low as 316).
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 can be oil quenched.

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