One of the top producers and suppliers of high-end stainless steel products, Vinit Stainless is situated in Chennai, India, and is well-known for its excellence, performance, and inventiveness. Stainless Steel 904L Flanges are among its best-selling products; they are designed to provide remarkable mechanical strength and resistance to corrosion in demanding industrial settings. These flanges, which come in a variety of designs like slip-on, blind, and weld neck, meet strict international standards. They guarantee exceptional performance in extremely corrosive media, such as sulfuric acid and chloride-rich environments, because they are made from non-stabilized austenitic stainless steel 904L, which has high concentrations of nickel and chromium.
Stainless Steel 904L is a non-stabilized, austenitic stainless steel alloy that contains trace amounts of copper and titanium along with 19–23% chromium, 23–28% nickel, and 4–5% molybdenum. Excellent corrosion resistance is offered by this composition, particularly in environments that contain acid and chloride. The flanges have exceptional mechanical qualities, such as high elongation and ductility, yield strength of about 220 MPa, and tensile strength of up to 710 MPa. Because their structure holds up well in high-temperature and high-pressure environments, they can be used in oxidizing and reducing settings and provide dependable, maintenance-free performance even in the most demanding applications.
