With cutting-edge production techniques and rigorous quality control measures, Phehlukwayo Metal guarantees that every Stainless Steel 446 Rectangular Bar adheres to international standards. Their dedication to innovation, precision engineering, and customer satisfaction has made them a go-to supplier for essential industrial components throughout South Africa and beyond.
Stainless Steel 446 Rectangular Bars are made from high-chromium ferritic stainless steel alloys, typically containing about 23–27% chromium and low carbon levels. This unique blend gives them remarkable resistance to oxidation, sulfidation, and scaling, even at elevated temperatures. While they offer moderate strength and excellent resistance to thermal fatigue, it’s important to note that Stainless Steel 446 isn’t heat-treatable for hardening. However, it maintains its structural integrity even under extreme heat. Its ferritic structure also ensures good corrosion resistance in oxidizing and mildly reducing environments, making it a fantastic choice for high-temperature industrial applications that demand durability, stability, and long-lasting performance under thermal stress.

When selecting Stainless Steel 446 Rectangular Bars, consider factors like temperature resistance, corrosion resistance, and the specific environmental conditions. Additionally, ensure compatibility with the required mechanical properties and fabrication needs.
Stainless Steel 446 Rectangular Bars are not ideal for cryogenic applications due to their reduced toughness at low temperatures. For cryogenic use, materials with better low-temperature properties, like austenitic stainless steels, are recommended.
Stainless Steel 446 Rectangular Bars generally do not require additional corrosion protection coatings due to their inherent high corrosion resistance. However, in highly aggressive environments, coatings may be used for added protection.
These Stainless Steel 446 Rectangular Bars find their place in various applications where high-temperature and oxidation resistance is crucial. They are commonly used in industries such as furnace manufacturing, heat treatment, incineration, petrochemical processing, and power generation. These bars are perfect for components like heat exchanger parts, burner tubes, kiln linings, and exhaust systems. Their rectangular shape not only provides excellent load-bearing capacity for structural frames but also supports environments exposed to extreme heat. Thanks to their stability and corrosion resistance, they are also utilized in chemical processing applications, ensuring reliability in demanding conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
