Hemi Metals is a leading manufacturer of stainless steel 446 hex bars, known for their resistance to high temperature oxidation and excellent performance in aggressive environments Stainless steel is made of high chromium, ferritic a it is 2200°F and there is oxidation and carburization of these woods at temperatures up to (1200°C). Provide excellent resistance Stainless steel 446 hex panels are designed specifically for use in high-temperature applications such as furnace parts, heat exchangers, and industrial equipment, where resistance is required scratches and scratches under extreme conditions Their exceptional durability and chemical resistance make SS 446 hex bars portable materials to durability in harsh environments Makes it ideal for a variety of projects that need support.
Stainless Steel 446 Hex Bar is primarily composed of 23-27% chromium, which provides excellent oxidation and corrosion resistance at high temperatures. It contains up to 1% silicon to enhance resistance to carburization. The alloy also includes small amounts of manganese, carbon, and iron. In terms of mechanical properties, SS 446 Hex Bars offer a tensile strength of 480 MPa (70 ksi) and a yield strength of 275 MPa (40 ksi). They have high thermal stability, with a hardness range of 200-250 HB, making them ideal for extreme heat environments.

SS 446 Hex Bars offer excellent corrosion resistance, high strength, and durability, making them ideal for harsh industrial environments. Their resistance to oxidation and high-temperature stability ensure reliability in applications like heat exchangers, chemical processing, and petrochemical industries.
SS 446 Hex Bar has superior high-temperature strength and excellent resistance to oxidation compared to other stainless steel alloys like SS 304 or SS 316. Its enhanced durability and corrosion resistance make it ideal for high-stress environments, such as heat exchangers, where other alloys may degrade or weaken over time.
Common machining techniques for SS 446 Hex Bars include turning, milling, drilling, and grinding. Challenges include its high hardness and tendency to work-harden, which can lead to tool wear. Proper lubrication and slower cutting speeds are necessary to maintain tool life and achieve smooth, accurate finishes.
Stainless Steel 446 Hex Bar is widely used in high-temperature and corrosive environments due to its excellent oxidation and carburization resistance. Common applications include furnace parts, heat exchangers, boiler components, and other equipment exposed to elevated temperatures, such as exhaust systems in industrial machinery. SS 446 is also utilized in the chemical, petrochemical, and power generation industries for components requiring durability under extreme heat and corrosive conditions. Its ability to withstand high temperatures up to 2200°F (1200°C) makes it ideal for critical, high-stress applications in demanding environments.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
