Precipitation-Hardening (PH) Stainless Steel is a high-strength stainless steel that achieves its superior mechanical performance through a specialized precipitation-hardening heat-treatment process.
During this process, fine particles form within the steel’s microstructure, significantly increasing strength and hardness while maintaining excellent corrosion resistance and dimensional stability.
Key Characteristics
High Strength-to-Weight Ratio
• Exceptional tensile and yield strength with relatively low weight
Excellent Corrosion Resistance
• Performs well in marine, chemical, and industrial environments
Good Fabrication & Formability
• Easily machined and formed before final hardening treatment
Stable Mechanical Properties
• Retains strength and toughness even at elevated temperatures
Refining & Heat-Treatment Properties
• Undergoes controlled solution treatment, quenching, and aging
• Fine precipitates of copper, aluminum, or titanium form within the matrix
• Aging temperature and time allow precise control of strength and toughness
• Results in a uniform microstructure with enhanced tensile strength, hardness,
and fatigue resistance
Why Choose PH Stainless Steel
Precipitation-hardening stainless steel combines high mechanical strength, excellent corrosion resistance, and dimensional precision in a single material. It is ideal for demanding applications where reliability, weight reduction, and long-term performance are critical.
