17-4PH stainless steel in the Sta (stress-relieved annealed) condition is a precipitation-hardening martensitic stainless steel providing moderate strength with improved toughness and ductility, typically used in aerospace and defense applications requiring good corrosion resistance and machinability. This condition offers a balance between strength retention and dimensional stability for parts requiring stress relief after machining or forming.
