Kanish Metals, located in Dubai, UAE, stands out as a top manufacturer and supplier of premium stainless steel products, including the highly sought-after Stainless Steel 446 hollow bars. With a strong focus on precision and quality, Kanish Metals ensures that its products adhere to the highest industry standards. The 446 hollow bars are particularly well-suited for high-temperature applications, thanks to their remarkable resistance to oxidation and corrosion. Catering to sectors like power generation, petrochemicals, and manufacturing, Kanish Metals prides itself on timely deliveries and customized solutions that address the varied needs of its clients in the UAE and beyond.
Stainless Steel 446 hollow bars are primarily made up of iron, chromium (23-27%), along with trace amounts of nickel and other elements. The high chromium content grants them exceptional resistance to oxidation and corrosion, especially in high-temperature settings. They boast impressive mechanical properties, including high tensile strength (up to 520 MPa) and solid resistance to thermal fatigue and scaling. This material also shows remarkable resilience against sulfur-containing gases, making it perfect for high-heat, corrosive applications. Notably, Stainless Steel 446 has a low coefficient of expansion and retains its strength and durability even at elevated temperatures, reaching up to 1100°C.

SS 446 hollow bars typically contain 23-27% chromium, 1-2% silicon, 0.75% manganese, and small amounts of carbon, phosphorus, sulfur, and nickel, providing excellent resistance to high-temperature oxidation and corrosion.
Key benefits of SS 446 hollow bars include excellent high-temperature oxidation resistance, superior corrosion resistance, durability in harsh environments, and strength at elevated temperatures, making them ideal for furnace and chemical processing applications.
Stainless Steel 446 hollow bars find extensive use in industries that demand materials capable of enduring high temperatures and harsh environments. In power plants, they are crucial for creating components like furnace parts, heat exchangers, and flue gas desulfurization units. Within the petrochemical sector, 446 hollow bars are vital for reactor components, piping systems, and equipment that come into contact with sulfur-rich environments. Moreover, these hollow bars are integral to the production of parts for gas turbines, incinerators, and chemical processing equipment, where their ability to resist both high heat and corrosive substances is essential for dependable performance.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
