Descrição do produto
17-4PH Precipitation Hardening Stainless Steel Round Bar Stock
UNS S17400 / Grade 630 - A chromium-copper precipitation hardening stainless steel offering high strength and moderate corrosion resistance, maintaining performance up to 600°F (316°C).
Product Specifications
Product 17-4PH Stainless Steel Round Bar
Standard ASTM, GB, DIN, EN
Diameter 8 - 450mm
Length 6m per piece or custom cutting available
Finishing Black Bar / Bright Bar
Service Cutting, surface polishing, heat treatment
Brand Walsin, BAOSTEEL, TISCO, QINGSHAN
Material Properties
17-4PH is a precipitation hardening martensitic stainless steel with copper and niobium additions, combining high strength, hardness (up to 572°F/300°C), and corrosion resistance equivalent to Alloy 304 or 430 in many environments.
Key Features: Very high yield strength up to 1100-1300 MPa (160-190 ksi), excellent mechanical properties optimized through heat treatment, and adequate corrosion resistance for industrial applications.
Applications
  • Offshore equipment (foils, helicopter deck platforms)
  • Food processing industry
  • Pulp and paper manufacturing
  • Aerospace components (turbine blades)
  • Mechanical components
  • Nuclear waste casks
  • Engine components
  • Boat propeller shafts
  • Plastic molding dies
  • Valves and gears

Fabrication & Processing
Welding
Can be welded using all conventional methods without pre-heating. Careful design and welding practices are recommended for high-strength applications.
Machining
Best machined in solution-treated condition with machining rates similar to grade 304 stainless steel.
Alternative Material Comparison
Alternative Grade Reason for Selection
431 Higher toughness, better availability in some sizes
416 Free-machining martensitic steel, lower cost
316 Higher corrosion resistance but lower strength
