With cutting-edge technology and strict quality control in their manufacturing process, Isis Metals guarantees reliable performance and precise dimensions. Committed to customer satisfaction, they provide Stainless Steel 347H materials to various sectors, including petrochemical, oil and gas, power generation, and chemical processing throughout the Philippines.
Stainless Steel 347H Square Bars and Rods are a type of stabilized austenitic stainless steel, featuring chromium (17–19%), nickel (9–13%), and niobium, which boosts their resistance to intergranular corrosion. The “H” designation signifies a higher carbon content (0.04–0.10%), enhancing their strength at elevated temperatures. These bars showcase impressive tensile strength of around 515 MPa and yield strength of about 205 MPa, along with good ductility and oxidation resistance up to 900°C. Their robust mechanical properties and stability under thermal stress make them ideal for extended exposure to high temperatures and corrosive conditions.
