Isis Metals stands out as a reliable manufacturer and supplier of Stainless Steel 321H Round Bars and Rods right in the heart of Manila, Philippines. They pride themselves on delivering top-notch products that align with global standards. These bars and rods are crafted to perform exceptionally well in high-temperature and corrosive settings. With meticulous engineering, they offer remarkable strength, durability, and resistance to oxidation. At Isis Metals, every product goes through rigorous quality testing to meet international specifications. Their dedication to excellence serves various industries, including petrochemical, power generation, oil and gas, and heat exchangers, providing dependable stainless steel solutions for tough applications.
Stainless Steel 321H Round Bars and Rods are made from titanium-stabilized austenitic alloys, featuring chromium (17–19%), nickel (9–12%), and carbon (0.04–0.10%). The inclusion of titanium boosts resistance to carbide precipitation when exposed to high temperatures. These bars showcase impressive tensile strength of about 515 MPa and yield strength of 205 MPa, along with good elongation and toughness. The alloy is known for its excellent resistance to intergranular corrosion, scaling, and oxidation up to 900°C, making it perfect for environments that demand both high strength and heat resistance.
