Description

ASTM A182 F304H Flanges, SS 304H Slip On Flange, SS 304H Blind Flange Manufacturer in India Stainless Steel 304H Flanges are high-carbon variants of the standard 304 grade, offering enhanced strength and superior high-temperature resistance. Manufactured under ASTM A182 and ASME SA182 specifications, these flanges are widely used in pressure systems, heat exchangers, and high-temperature processing industries. The increased carbon content (0.04%–0.10%) improves creep resistance and mechanical strength, making SS 304H flanges ideal for applications requiring prolonged exposure to temperatures above 500°C (932°F). These flanges conform to ASME B16.5, B16.47, and MSS SP-44 dimensional standards, ensuring compatibility with various piping systems. Additionally, their low magnetic permeability and excellent corrosion resistance make them suitable for aggressive environments, including chemical and petrochemical industries. The mechanical properties of ASTM A182 F304H flanges include a minimum tensile strength of 515 MPa (75,000 psi) and yield strength of 205 MPa (30,000 psi), providing excellent structural integrity. With a Brinell hardness of 201 HB max, these flanges exhibit outstanding toughness and resistance to thermal expansion, reducing the risk of failure in extreme conditions. Chemical composition features 18-20% chromium and 8-10.5% nickel, ensuring superior oxidation resistance, while the carbon enhancement improves stress rupture properties. These flanges are available in multiple types, including Weld Neck, Slip-On, Blind, Socket Weld, Threaded, and Lap Joint, catering to diverse industry requirements. Their superior intergranular corrosion resistance further enhances durability, making them a preferred choice for steam piping, boilers, and furnace components.
