Maria Pipes and Tubes, Kuala Lumpur, Malaysia, is a well-known manufacturer and supplier of high-quality Stainless Steel 347/347H Seamless Tubing. With a reputation for excellence and reliability, we cater to the domestic and international markets from diverse industries. Our seamless 347/347H tubing is specially developed to provide outstanding performance under high temperatures and corrosive conditions with excellent strength, durability, and weldability. Produced with advanced technology and rigorous quality inspection, our tubing is up to international standards, providing uniform performance in demanding applications. Maria Pipes and Tubes stands for supplying precision-engineered products according to client specifications.
Stainless Steel 347/347H Seamless Tubing consists largely of chromium (17–20%) and nickel (9–13%), stabilized with columbium (niobium) and occasionally with tantalum, increasing its resistance to intergranular corrosion. Grade 347H has higher carbon levels, enhancing high-temperature strength. The tubing usually has a tensile strength of approximately 485 MPa, yield strength of 170 MPa, and elongation of about 35%. Such mechanical strengths qualify it for use where heat, pressure, and mechanical stress are involved. Its superior resistance to creep and oxidation when exposed to high temperatures recommends it as a dependable material for thermal and stress-high environments.
