630 (17-4PH) Stainless Steel Strip – Precision Engineered for Demanding Industries
Compliance: AMS 5643, ASTM A564, EN 1.4542
Material Type: Martensitic Precipitation-Hardening Stainless Steel
Why Choose 630 Stainless Steel Strip?
630 stainless steel strip (17-4PH) is engineered to deliver unmatched performance in environments requiring fatigue resistance, dimensional stability, and long-term reliability. Its unique aging process allows customization of mechanical properties, making it a top choice for mission-critical applications.
Standout Advantages
-
Tailored Hardness: Adjustable via heat treatment (e.g., H925, H1025, H1075) to balance strength and toughness.
-
Stress-Corrosion Resistance: Superior to standard martensitic steels in chloride-rich or acidic settings.
-
Thermal Stability: Retains properties at temperatures up to 300°C (570°F).
-
Cost-Effective Machining: Easily fabricated in annealed state, then hardened post-forming.
Enhanced Composition & Performance
Key Alloying Elements:
-
Chromium (15-17.5%): Ensures oxidation and corrosion resistance.
-
Nickel (3-5%): Enhances toughness and thermal stability.
-
Copper (3-5%): Facilitates precipitation hardening for peak strength.
Post-Aging Properties (H1150 Condition):
-
Tensile Strength: 1000 MPa (145 ksi)
-
Yield Strength: 800 MPa (116 ksi)
-
Elongation: 12%
-
Impact Resistance: 35 J (26 ft-lb)
Customization Options
-
Thickness Range: 0.1 mm – 5.0 mm (±0.01 mm precision)
-
Width Tolerance: Custom slitting up to 1200 mm.
-
Surface Treatments: Electropolished, passivated, or brushed finishes.
-
Certifications: RoHS compliant, NACE MR0175 for sour service environments.
Industry-Specific Applications
-
Defense: Missile components, armor systems.
-
Energy: Turbine blades, nuclear reactor parts.
-
Automotive: High-stress fasteners, valve springs.
-
Electronics: Sensor housings, connectors.
Supply Chain Excellence
-
Lead Time: Standard 2–4 weeks; expedited options available.
