Stainless Steel 17-7 PH Coil

Stainless Steel 17-7 PH Coil is an age-hardenable chromium-nickel alloy that contains 17% chromium, 7% nickel and 3.5 to 5.5% Aluminum. This alloy exhibits good strength, fatigue resistance, high hardness and corrosion resistance when aged at relatively high temperatures over long periods. Its toughness suits many industries, such as aerospace and medical device production.


Stainless Steel 17-7 PH Coil is commonly used in aerospace components, aircraft fittings, nuclear reactors, pump shafts and medical applications due to its excellent mechanical properties. It has a high strength-to-weight ratio and superior corrosion resistance. Additionally, it is nonmagnetic in the annealed condition and can be hardened by cold working for enhanced wear or impact resistance. It also has great formability, making it suitable for numerous applications requiring tight tolerances.
