Stainless Steel 446 Hex Bar is a high-chromium ferritic stainless steel celebrated for its remarkable resistance to corrosion and oxidation, even at high temperatures. Typically, it contains 23–27% chromium, 0.2% carbon, and small amounts of manganese, silicon, and other elements that boost its hardness and strength. Mechanically, it boasts a tensile strength ranging from 450–750 MPa and a yield strength of about 275–450 MPa, along with a good elongation of 15–20%. This steel maintains its structural integrity under high thermal conditions, resists scaling, and offers excellent wear resistance, making it perfect for demanding industrial applications.

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 Bars find extensive use in situations that require high-temperature corrosion resistance and strength. They are particularly suited for furnace parts, heat exchangers, kiln components, and industrial oven parts, thanks to their ability to endure prolonged exposure to heat and harsh environments. Additionally, they are utilized in chemical processing equipment, the petrochemical industry, and high-temperature piping systems. Their wear resistance, structural durability, and oxidation resistance make them ideal for automotive exhaust systems, turbine components, and other machinery that faces high temperatures. These bars ensure reliability and longevity in critical applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
