Based in Chennai, India, Vinit Stainless is a well-known producer and supplier of stainless steel 304H flanges. Vinit Stainless, which has been producing stainless steel for decades, specialises in high-temperature flanging solutions that are designed to satisfy demanding industrial specifications. The high carbon content of SS 304H flanges is well known for improving strength and performance at high temperatures. These flanges are perfect for crucial applications in the chemical, power, and refinery industries because they are made with premium raw materials and state-of-the-art technology. Vinit Stainless is a well-known brand in both domestic and foreign markets thanks to its dedication to precise engineering, prompt delivery, and outstanding quality.
304H flanges are made of high-carbon austenitic stainless steel, which contains 8–10.5% nickel, 18–20% chromium, and 0.04%–0.10% carbon. The increased carbon improves creep resistance and strength at high temperatures. These flanges have good ductility and elongation, with a yield strength of about 205 MPa and a tensile strength of about 515 MPa. In addition to having good weldability and formability, SS 304H offers outstanding resistance to oxidation and corrosion at high temperatures. It is appropriate for high-heat, pressure-bearing applications because it operates dependably in continuous service environments up to 900°C.

SS 304H long weld neck flanges are designed for high-stress applications, featuring a long tapered neck that provides a strong, continuous weld connection. They offer excellent strength and resistance to leakage.
SS 304H lap joint flanges are versatile components designed for ease of assembly and disassembly. They feature a loose fit, allowing for easy alignment and maintenance, with excellent resistance to corrosion.
SS 304H reducing flanges are used to connect pipes of different diameters, providing a smooth transition between sizes. They ensure a secure, leak-proof joint while offering strong corrosion resistance and durability.
In high-temperature, high-pressure piping systems where mechanical strength and heat resistance are essential, stainless steel 304H flanges are widely used. Heat exchangers, superheaters, steam pipelines, and pressure vessels are typical uses in the petrochemical and power generation sectors. Chemical manufacturing facilities, thermal processing systems, and oil refineries also use these flanges. They are perfect for joining pipes that carry hot gases, steam, or corrosive fluids because of their exceptional weldability and resistance to corrosion. These flanges are necessary in high temperature service environments because of the high carbon content of 304H, which guarantees long-term structural stability under thermal stress.
