Based in Chennai, India, Vinit Stainless is a reputable provider of high-end stainless steel products that offer dependable solutions to a variety of industries. Stainless Steel 17-7 PH Flanges are one of its specialty products; they are made from a precipitation-hardening alloy that combines exceptional corrosion resistance, high strength, and superior hardness following heat treatment. These flanges are especially designed to withstand high temperatures and stress in demanding applications. Vinit Stainless is a preferred partner for high-performance stainless steel flanges in India and around the world because it guarantees precision engineering, quality assurance, and on-time delivery.
About 17% chromium, 7% nickel, and trace amounts of aluminum for precipitation hardening make up stainless steel 17-7 PH flanges (UNS S17700). These flanges have outstanding fatigue resistance, high tensile strength (up to 1310 MPa), and yield strength (up to 1170 MPa). They maintain their mechanical strength at high temperatures and undergo aging heat treatment, which greatly increases their hardness. 17-7 PH flanges are perfect for components subjected to harsh chemical or marine environments, cyclic loading, and good machinability, thermal stability, and oxidation resistance.
