Chung Metal offers heat- and corrosion-resistant Stainless Steel 446 Round Bars and Rods, a ferritic stainless steel known for superior resistance to oxidation, sulfidation, and thermal fatigue. SS 446 is exceptionally durable in high-temperature service and is suitable for heat exchangers, furnace parts, and incinerators. Its circular bar shape is ideal for mechanical components used in thermal cycling conditions. Chung Metal produces SS 446 bars with high structural strength and heat resistance for exacting thermal processing applications.
SS 446 has 23–27% chromium, low carbon content of ~0.2%, and no nickel. Its tensile strength is 450–650 MPa, its yield strength is 200–300 MPa, and it is magnetic. It is stable up to 1100°C and provides outstanding resistance to scaling and oxidation. The round shape provides consistent strength and fabrication ease.

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.
446 round bars/rods are applied in furnace components, burners, heat exchanger tubes, kilns, boiler baffles, and thermal shields. It is resistant to oxidation in sulfur-containing atmospheres and maintains resistance to thermal cycling. SS 446 is suitable for chemical processing, melting of metals, and exhaust systems and is widely applied in cement plants, petrochemical refineries, and waste incineration. The round bar form provides for thermal stability and mechanical integrity in rotating or heavy-load components. Chung Metal provides heavy-duty thermal conditions with custom lengths and surface finishes.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
