Maria Pipes and Tubes, a leading manufacturer and supplier based in Kuala Lumpur, Malaysia, offers premium Stainless Steel 348H Tubing known for its outstanding high-temperature strength and corrosion resistance. Manufactured to stringent international standards, these tubes deliver exceptional performance in environments exposed to elevated temperatures and stress. Crafted from high-quality materials using advanced production methods, Stainless Steel 348H Tubing from Maria Pipes and Tubes ensures precise dimensions, excellent durability, and long service life. This makes them a reliable choice for critical applications in power generation, aerospace, and petrochemical industries.
Stainless Steel 348H tubing is composed of chromium (17-19%), nickel (9-13%), and columbium (10xC to 1.10%), with minor amounts of carbon, manganese, and silicon. It offers excellent corrosion resistance, especially in high-temperature environments, and maintains its strength and stability up to 1500°F. Mechanical properties include high tensile strength, excellent creep resistance, and good yield strength. The advantages of 348H tubing include superior resistance to intergranular corrosion, good weldability, and suitability for nuclear applications due to its ability to resist radiation-induced damage.
