Khaleed Stainless is a reputable manufacturer and supplier of Stainless Steel 304H Pipes based in Riyadh, Saudi Arabia. These pipes are specifically designed for high-temperature and high-pressure applications, making them a popular choice for heat exchangers, boilers, and refinery systems. The 304H grade stands out due to its higher carbon content, which gives it enhanced mechanical strength compared to standard 304. At Khaleed Stainless, we offer SS 304H pipes in various dimensions and finishes to meet international standards. Our commitment to reliability, technical precision, and timely delivery allows us to serve clients throughout Saudi Arabia and the wider Middle East.
Stainless Steel 304H Pipes consist of 18–20% chromium, 8–11% nickel, and a higher carbon content (0.04–0.10%) than standard 304, which boosts their strength and heat resistance. These pipes boast a tensile strength of approximately 515–760 MPa and excel in high-temperature environments. The increased carbon content enhances creep resistance, making this alloy suitable for extended use at elevated temperatures. SS 304H is non-magnetic when annealed and provides excellent weldability and corrosion resistance in moderately aggressive settings.
