17-4PH (precipitation-hardened stainless steel) in H1100 condition is a martensitic stainless steel strengthened by copper and niobium precipitation, offering yield strength around 1,310 MPa with good corrosion resistance and toughness, used extensively in aerospace applications including fasteners, shafts, and structural components. The H1100 temper provides a balance of high strength and ductility through controlled aging after solution treatment and cold work.
