This particular stainless steel is distinguished by its high chromium content, which gives it exceptional resistance to scaling and oxidation at elevated temperatures. It’s a ferritic grade, meaning it is magnetic and cannot be hardened by heat treatment. The material offers good mechanical properties, including respectable strength and ductility, allowing it to be fabricated into various components. Its key advantage lies in its ability to withstand corrosive atmospheres, particularly those containing sulfur, making it a practical choice for many challenging industrial settings.

Yes, Stainless Steel 446 Square Bars are highly corrosion-resistant due to their high chromium content. They are particularly effective in resisting oxidation and scaling at elevated temperatures.
Yes, Stainless Steel 446 square bars can be welded using appropriate welding techniques like TIG or MIG welding. However, preheating and post-weld heat treatment may be required to minimize the risk of cracking and maintain structural integrity.
Yes, we provide stainless steel 446 square bars and rods in standard and customized dimensions and polishes to meet your specific project requirements. For more details mail us on sales@sadikimetals.com
The unique properties of these square bars and rods make them ideal for applications where heat and corrosion are major concerns. You’ll often find them used in the construction of industrial furnaces, heat exchangers, and high-temperature processing equipment. They are also exceptionally well-suited for use in sulfite digesters within the pulp and paper industry and various components for thermal oxidation systems. Their square profile is perfect for creating sturdy frames, supports, and custom fixtures that require a combination of structural integrity and long-term resistance to aggressive environments.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
Sadiki Metals is a leading manufacturer, supplier, and exporter of high-quality bars, rods, and forgings, catering to various industries in Kinshasa, Congo
