Maria Pipes and Tubes, located in Kuala Lumpur, Malaysia, is a reputable manufacturer and supplier of top-notch stainless steel tubing. Their Stainless Steel 304H Tubing is specifically designed for high-temperature and high-pressure applications, offering a perfect blend of strength, oxidation resistance, and durability against corrosion. Thanks to their polished fabrication processes and rigorous quality control, this tubing is essential for critical industries like petrochemical, power generation, and heat exchange systems. Maria Pipes and Tubes guarantees that each piece of tubing meets international standards, ensuring reliable performance even in the toughest thermal and mechanical conditions.
Stainless Steel 304H Tubing is composed of 18–20% chromium and 8–10.5% nickel, with a higher carbon content of up to 0.10% to boost its strength at high temperatures and improve creep resistance ([valouralloys.com][1], [Multi Metals India][2]). In terms of mechanical properties, it boasts a minimum tensile strength of 515 MPa, a yield strength of 205 MPa, and an elongation of at least 40% ([valouralloys.com][1], [Multi Metals India][2]). These characteristics, along with a density of about 8 g/cm³ and a melting point near 1400 °C, make it an excellent choice for tubing in extreme conditions ([Multi Metals India][2]).
