PH13-8Mo is a martensitic precipitation-hardening stainless steel (13% Cr, 8% Ni, Mo, Al) that achieves ultra-high strength in the H1000 condition through age hardening, providing yield strengths around 1310 MPa with good corrosion resistance and fatigue performance for aerospace fasteners, bearings, and critical structural components. The H1000 temper represents maximum strength conditioning and maintains useful strength to approximately 300°C with excellent bearing fatigue and fatigue crack growth resistance, making it suitable for demanding load-bearing applications where both strength and corrosion resistance are required.
