About 17% chromium and 7% nickel make up stainless steel 17-7 PH pipe fittings, with 0.75–1.5 percent aluminium added to improve precipitation hardening. These fittings made of austenitic-martensitic stainless steel are very strong and have good fatigue resistance. Depending on the heat treatment (usually Condition CH 900 or TH 1050), the yield strength is approximately 758 MPa and the tensile strength can reach up to 965 MPa. The alloy is perfect for high-load or pressure-bearing pipe systems in demanding environments because it has good formability when annealed, moderate corrosion resistance, and exceptional spring-like qualities.
