Stainless Steel 17-4 PH Flanges

Stainless Steel 17-4 PH Flanges is a high-strength precipitation-hardened stainless steel with excellent corrosion resistance. It has good formability, toughness, and weldability properties. The 17-4 PH, also known as Grade 630 or UNS S17400, contains around 15–17.5% chromium and 3–5% nickel in its composition, along with smaller amounts of carbon, manganese, silicon and phosphorus. Its high strength is due to the addition of copper and niobium, which further adds resistance to stress corrosion cracking.

Stainless Steel 17-4 PH Flanges are high-strength alloys used in aerospace and industrial applications due to their excellent corrosion resistance, superior mechanical properties, and ease of fabrication. They have a wide range of applications, such as structural components with higher fatigue resistance than other alloys and fasteners operating under extreme temperature swings. They also possess good wear resistance, so they can often be found in valve parts requiring frequent repairs. Furthermore, these flanges also display good formability characteristics, which allow for bending without losing structure integrity. In short, Stainless Steel 17-4 PH Flanges offer strength, flexibility, and superior corrosion resistance, making them the perfect choice for any application where reliability is paramount.
