Renowned for their dedication to quality, innovation, and customer satisfaction, Andre Stainless serves a variety of industries throughout Singapore and Southeast Asia. Whether it’s for petrochemical, marine, or power generation applications, they ensure that every product is designed for peak performance and longevity, establishing themselves as a trusted name in the stainless steel manufacturing world.
The Stainless Steel 347H Pipe Fittings from Andre Stainless are primarily made up of chromium (17–19%), nickel (9–13%), and columbium-tantalum stabilizers, which enhance their strength at high temperatures. The carbon content is slightly higher (up to 0.10%) compared to standard 347, boosting creep resistance. These fittings boast impressive mechanical properties, including a tensile strength of about 515 MPa, a yield strength of around 205 MPa, and remarkable elongation and toughness. These features make 347H perfect for high-temperature service environments, providing excellent resistance to intergranular corrosion and oxidation, particularly in pressure-containing and high-stress systems.
