15-5PH is a martensitic precipitation hardening stainless steel with improved toughness and ductility compared to 17-4PH. It features high strength, good hardness, superior corrosion resistance and excellent transverse mechanical properties. After solution annealing and aging treatment, it delivers stable structural performance, good wear resistance and outstanding dimensional stability. Widely used in aerospace components, food processing equipment, oil and gas parts, valve accessories and high

Advantage

1.High strength and hardness after aging treatment, excellent structural bearing capacity 2.Better toughness and ductility than 17-4PH, stronger impact resistance 3.Moderate corrosion resistance, suitable for wet and weak corrosive environments 4.Fine machinability and heat treatment stability for industrial mass processing
