Our Stainless Steel 446 Round Bars and Rods are mainly made up of iron, chromium (23–27%), along with small amounts of manganese, silicon, and carbon. This ferritic stainless steel grade is known for its excellent resistance to oxidation, scaling, and sulfidation at high temperatures. It provides moderate tensile strength, good hardness, and outstanding dimensional stability, even when faced with thermal stress. The material’s non-hardenable nature ensures exceptional toughness and workability, while its low carbon content helps reduce carbide precipitation, boosting corrosion resistance and longevity in harsh operating conditions.

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.
Stainless Steel 446 Round Bars and Rods find extensive use in industries that require exceptional heat and corrosion resistance. They are perfect for furnace parts, heat exchangers, kiln linings, boiler baffles, and exhaust systems. With the ability to withstand scaling up to 1100°C, this alloy is well-suited for applications in petrochemical plants, power generation, and metallurgical industries. Moreover, its durability and strength make it a go-to choice in construction, thermal processing equipment, and environmental engineering projects where performance in extreme temperatures is crucial.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
