Shawn Flanges, located in Houston, USA, is a well-known manufacturer and supplier of high-performance Stainless Steel 17-4 PH Flanges, designed for applications that require both high strength and moderate corrosion resistance. This type of stainless steel, known as 17-4 PH (Precipitation Hardening), merges the corrosion resistance typical of stainless steel with the toughness and strength found in heat-treated alloys. Our selection of flanges includes weld neck, slip-on, socket weld, threaded, blind, and lap joint options, all crafted to comply with ASTM A182 and ASME B16.5 standards. At Shawn Flanges, we prioritize precision manufacturing and rigorous quality control, making our 17-4 PH flanges perfect for aerospace, petrochemical, and marine applications.
Stainless Steel 17-4 PH Flanges from Shawn Flanges are made up of about 15–17.5% chromium, 3–5% nickel, 3–5% copper, and 0.15–0.45% niobium, with the remainder being iron. After undergoing heat treatment (aging), these flanges can reach impressive tensile strengths of up to 1100 MPa, yield strengths exceeding 1000 MPa, and hardness levels between 35–44 HRC, depending on their condition (ranging from H900 to H1150). They also offer good corrosion resistance similar to that of 304 stainless steel, along with excellent toughness and dimensional stability, even after machining and aging.
