Neith Metals, based in Cairo, Egypt, has built a solid reputation as a reliable manufacturer and supplier of top-notch stainless steel products, with a particular focus on Stainless Steel 446 Hex Bars. This company is celebrated for crafting materials that are not only corrosion-resistant but also heat-resistant and durable, all while adhering to international standards. Thanks to their state-of-the-art manufacturing facilities and rigorous quality assurance processes, Neith Metals guarantees that every product delivers consistent performance and precision. Their Stainless Steel 446 Hex Bars are designed to excel in oxidation resistance, mechanical strength, and dimensional accuracy, making them perfect for demanding industrial, engineering, and high-temperature applications.
Stainless Steel 446 Hex Bars are ferritic stainless steel alloys that mainly consist of 23–27% chromium, featuring a very low carbon content (≤0.20%) along with small amounts of manganese, silicon, and molybdenum. This unique composition grants them outstanding resistance to oxidation, scaling, and sulfur attack even at high temperatures. In terms of mechanical properties, they boast a tensile strength of around 550 MPa and a yield strength close to 350 MPa, along with remarkable stability under thermal stress. These bars maintain their strength and corrosion resistance even in high-temperature settings, making them ideal for applications that require both heat and oxidation resistance.

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.
You’ll find Stainless Steel 446 Hex Bars widely utilized in industries where heat, oxidation, and corrosion resistance are essential. They’re commonly found in furnace components, heat exchangers, boiler tubes, and kiln parts. Additionally, they play a vital role in petrochemical, power generation, and thermal processing equipment. Thanks to their impressive high-temperature performance, these bars are perfect for operations that involve continuous exposure to heat and corrosive gases. The hexagonal shape not only facilitates machining but also provides structural strength, making Stainless Steel 446 Hex Bars a go-to choice for manufacturing parts that need to withstand harsh environments while ensuring durability, precision, and longevity.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
