SUS630 Stainless Steel: Precipitation Hardening Alloy Benefits

Key Benefits of SUS630 (17-4PH)

Exceptional Strength & Hardness: Achieves very high mechanical properties after a single low-temperature aging treatment.

Good Corrosion Resistance: Offers corrosion resistance comparable to Type 304 stainless steel, superior to many other high-strength steels.

Excellent Toughness: Maintains good ductility and toughness, even at sub-zero temperatures in softer conditions.

Minimal Distortion: Low-temperature aging prevents significant warping, crucial for precise components.

Versatile Heat Treatment: Can be supplied in solution-treated (machinable) or age-hardened states, allowing customization.

Good Weldability: Low carbon content minimizes carbide precipitation, improving weld quality.

Common Applications

Aerospace: Aircraft parts, landing gear.

Chemical Processing: Pump shafts, valve components.

Energy Sector: Turbine blades, nuclear components.

Manufacturing: Fasteners, springs, pins, propeller shafts.

Medical: Surgical instruments, implants
