Stainless Steel 446 Hex Bars are primarily made of iron, featuring a high chromium content (23–27%) along with small amounts of molybdenum, silicon, and manganese. This ferritic stainless steel grade is known for its remarkable resistance to oxidation, sulfidation, and corrosion at elevated temperatures. In terms of mechanical properties, it boasts a tensile strength of about 485 MPa and a yield strength of around 275 MPa, along with commendable creep resistance. While it may not be as formable as austenitic grades, 446 hex bars excel in thermal stability, making them suitable for applications that involve continuous exposure to high heat and corrosive 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 Bars find their place in a variety of high-temperature and corrosive applications. They are widely used in industrial furnaces, heat exchangers, and burner assemblies due to their impressive resistance to scaling and oxidation. In the chemical and petrochemical sectors, they are utilized for equipment that comes into contact with aggressive chemical media. Power plants incorporate these hex bars in boiler components and superheater tubes. Furthermore, they are employed in thermal processing facilities, kiln linings, and incinerators. Their exceptional thermal and corrosion resistance makes them perfect for demanding environments that require long-lasting performance.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
