For businesses in Safat and across Kuwait seeking exceptional high-temperature resilience, Nimish Metal offers the Stainless Steel 446 Hollow Bar. We take pride in providing a product specifically engineered to withstand extreme heat and oxidation, making it a superior choice for demanding industrial environments. Our commitment as a local manufacturer and supplier is to deliver not just materials, but reliable performance and durability that your critical projects depend on.
The strength of Stainless Steel 446 lies in its high chromium content, typically around 23%, which creates an outstanding resistance to scaling at temperatures up to 1100°C. This alloy also offers good general corrosion resistance and impressive mechanical properties, including excellent yield strength and structural integrity. These characteristics ensure the hollow bar maintains its shape and performance under intense thermal stress, providing long-lasting service in the toughest conditions.

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.
This unique combination of properties makes the 446 Hollow Bar indispensable in sectors like furnace construction, heat treatment fixtures, and high-temperature chemical processing equipment. You’ll often find it used for radiant tubes, thermowells, and heat exchangers where other steels would fail. Its hollow bar form is particularly valuable for creating components that require a perfect balance of high strength and reduced weight, leading to more efficient and durable thermal systems.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
