A reliable producer and supplier of stainless steel 446 hex bars, George Metals is well-known for its outstanding performance in harsh and hot conditions. At temperatures as high as 2200°F (1200°C), SS 446, a ferritic stainless steel with a high chromium content, provides exceptional resistance to oxidation and carburization. These hex bars are perfect for furnace parts, heat exchangers, and high-temperature equipment because they are made for demanding industrial applications. George Metals guarantees premium SS 446 products with exceptional mechanical stability and chemical resistance that support vital operations in a variety of industries and provide long-lasting durability under harsh circumstances.
The main component of stainless steel 446 hex bars is chromium, which provides exceptional resistance to oxidation and scaling at high temperatures. In addition to iron, carbon, manganese, and trace elements, the alloy contains up to 1% silicon for improved resistance to carburization. Mechanically, SS 446 offers a Brinell hardness of 200–250 HB, a yield strength of 275 MPa (40 ksi), and a tensile strength of roughly 480 MPa (70 ksi). The alloy is a dependable option for environments that are both chemically aggressive and heat-intensive because it retains its structural integrity under thermal cycling conditions.

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.
Industries that need materials that can withstand high temperatures and corrosive environments frequently use SS 446 Hex Bars. Heat exchangers, boiler parts, furnace components, and industrial exhaust systems subjected to constant high heat are important applications. They are also utilized for parts subjected to oxidation, sulfidation, and carburization in the petrochemical, chemical, and power generation sectors. For long-term dependability in thermal processing and combustion systems, SS 446 is the material of choice because of its resistance to scaling up to 2200°F (1200°C), which guarantees steady performance in high-stress situations.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
