Catering to various industries like power generation, chemical processing, marine, and automotive, Phehlukwayo Metal guarantees dependable materials that are perfect for demanding applications requiring high-temperature strength, oxidation resistance, and long-lasting performance in tough operating conditions.
Stainless Steel 446 Round Bars and Rods are ferritic stainless steels primarily made of iron, containing about 23–27% chromium, along with small amounts of nickel and trace elements such as carbon, manganese, and silicon. This unique composition provides 446 stainless steel with excellent resistance to oxidation and scaling at high temperatures, as well as strong corrosion resistance in mildly corrosive environments. The material retains high tensile strength and hardness, coupled with good thermal stability. Its ferritic microstructure ensures dimensional stability and resistance to stress corrosion cracking, making it a great choice for applications that demand long-term reliability in high-temperature and corrosive settings.

Stainless Steel 446 Round Bars/Rod are not typically recommended for cryogenic applications, as their ferritic structure may become brittle at extremely low temperatures, compromising their performance and toughness.
To choose the right Stainless Steel 446 Round Bars/Rod, consider factors like the operating temperature, corrosion resistance requirements, and specific environmental conditions, ensuring compatibility with your application’s demands.
Yes, Stainless Steel 446 Round Bars/Rod should undergo regular inspection to ensure they maintain their integrity, especially in high-temperature or corrosive environments, to detect any potential wear or damage.
These Stainless Steel 446 Round Bars and Rods find extensive use in industries where high-temperature performance and corrosion resistance are essential. They’re often utilized in furnace components, heat exchangers, boiler parts, and industrial ovens, thanks to their ability to endure extreme heat without scaling or warping. In the chemical processing and marine sectors, they serve as valves, shafts, and fasteners that are exposed to moderately corrosive environments. The automotive and power generation industries also rely on 446 stainless steel bars and rods for high-performance applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
