Stainless Steel 17-7 PH pipes are primarily made up of iron, with 16–18% chromium, 6–8% nickel, and trace amounts of copper and manganese. This precipitation-hardening alloy boasts impressive mechanical properties, such as high tensile strength, excellent fatigue resistance, and remarkable hardness after heat treatment. It also provides outstanding corrosion resistance, especially in oxidizing and mildly corrosive environments. With a yield strength typically between 1,200 and 1,400 MPa and an elongation of 5–10%, these pipes maintain their structural integrity even under high stress, making them perfect for demanding applications that require both strength and durability in moderate to severe service conditions.
