Isis Metals, a reputable manufacturer and supplier located in Manila, Philippines, proudly offers top-quality Stainless Steel 446 Hex Bars. These bars are celebrated for their exceptional resistance to oxidation, scaling, and high-temperature corrosion. Crafted with precision and in line with international quality standards, they’re perfect for tough industrial settings. Stainless Steel 446 is a ferritic stainless steel that excels in environments exposed to heat, sulfurous gases, and oxidizing conditions. With a commitment to superior dimensional accuracy, excellent surface finish, and consistent quality, SS 446 Hex Bars are the go-to choice for industrial, mechanical, and structural applications.
Stainless Steel 446 Hex Bar is made up of 23–27% chromium, up to 1.5% manganese, 1% silicon, and a maximum of 0.20% carbon. The high chromium content ensures outstanding resistance to oxidation and corrosion, even at high temperatures. It boasts a tensile strength of around 485 MPa and impressive creep strength, along with the magnetic properties typical of ferritic stainless steels. While SS 446 cannot be hardened through heat treatment, it maintains remarkable dimensional stability, mechanical durability, and oxidation resistance, making it an excellent fit for high-temperature 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 extensive use in industries that demand superior heat and oxidation resistance. They’re perfect for crafting furnace parts, burner nozzles, boiler components, heat exchangers, and kiln linings. Thanks to their stability and resistance to sulfurous gases, they’re also ideal for petrochemical, power generation, and incineration equipment. Additionally, SS 446 Hex Bars are utilized in exhaust systems, thermal processing units, and chemical processing equipment that operate at high temperatures. Their unique blend of corrosion resistance, thermal durability, and mechanical strength ensures they last for the long haul.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
