Aman Pipes and Tubes, a prominent manufacturer and supplier located in Hyderabad, India, is dedicated to providing top-notch Stainless Steel 304H Pipes tailored for demanding industrial needs. With its high carbon content, 304H is engineered to deliver exceptional strength in high-temperature settings, making it perfect for those tough environments. Our pipes boast precise dimensions, a superior surface finish, and impressive corrosion resistance, earning the trust of industries like power generation, chemical processing, and heat exchange systems. At Aman Pipes and Tubes, we prioritize consistent quality and dependable performance, offering 304H pipes in various sizes and specifications that meet both national and international standards.
Stainless Steel 304H is an austenitic stainless steel that contains 18–20% chromium, 8–11% nickel, and a higher carbon content (0.04–0.10%) compared to standard 304, which boosts its strength at elevated temperatures. It features a tensile strength of about 585 MPa, a yield strength of 240 MPa, and an elongation of 40%. With excellent oxidation resistance and good weldability, 304H is well-suited for pressure vessels and structural components in high-heat conditions. Its mechanical and chemical stability makes it a reliable choice for critical applications that operate at high temperatures.
