Isis Metals stands out as a leading manufacturer and supplier of Stainless Steel 446 Hollow Bars, proudly based in Manila, Philippines. The company has built a solid reputation for providing top-notch stainless steel products that boast remarkable resistance to heat, oxidation, and corrosion. Crafted from high-quality raw materials and utilizing cutting-edge production technology, these hollow bars adhere to global quality standards. Isis Metals offers a variety of sizes and wall thicknesses for their Stainless Steel 446 Hollow Bars, ensuring they deliver durability, precision, and performance for sectors like power generation, petrochemical, furnace manufacturing, and heat treatment applications.
These Stainless Steel 446 Hollow Bars are mainly made up of iron, chromium (23–27%), along with trace amounts of manganese, silicon, and carbon, while containing little to no nickel. This ferritic stainless steel grade is known for its excellent resistance to oxidation and sulfidation at elevated temperatures, reaching up to 1100°C. In terms of mechanical properties, it boasts a tensile strength of 485–650 MPa and a yield strength of around 275 MPa, along with outstanding dimensional stability under thermal stress. The high chromium content plays a key role in providing superior corrosion resistance, especially in harsh and scaling-prone environments.
