Al Summan Metals, a top manufacturer and supplier based in Dubai, UAE, focuses on high-quality **Stainless Steel 446 Hex Bars**. These bars are renowned for their outstanding corrosion resistance, notable strength at elevated temperatures, and all-around durability. Manufactured with precision and according to international standards, they offer superior performance even in the most demanding industrial environments. Owing to their high chromium and low carbon composition, 446 stainless steel is distinguished by its excellent resistance to oxidation, scaling, and pitting, keeping them dependable over the long term. Al Summan Metals’ 446 Hex Bars are used across numerous sectors, such as chemical processing, power generation, marine applications, and high-temperature environments, where they offer both structural integrity and operational efficiency under extreme conditions.
These Stainless Steel 446 Hex Bars consist primarily of 23–27% chromium, with a carbon content of ≤0.2%, plus small amounts of manganese, silicon, and molybdenum. This distinctive makeup provides them with exceptional resistance to corrosion and oxidation, particularly at high temperatures. They feature a tensile strength between 450–650 MPa, a yield strength of 200–300 MPa, and an elongation of 20–30%, while still retaining good hardness and toughness. Their capacity to endure high temperatures combined with their mechanical strength makes them ideal for uses that require lasting durability in demanding environments.

SS 446 Hex Bars deliver outstanding corrosion resistance, superior strength, and long-lasting durability, which makes them well-suited for demanding industrial settings. Their oxidation resistance and stability at high temperatures guarantee dependable performance in uses such as heat exchangers, chemical processing, and petrochemical industries.
SS 446 Hex Bar offers greater strength at high temperatures and outstanding oxidation resistance when set against other stainless steel grades such as SS 304 or SS 316. Its improved durability and resistance to corrosion make it well suited for demanding, high-stress applications like heat exchangers, where other alloys might break down or lose strength as time passes.
Machining methods frequently used for SS 446 Hex Bars are turning, milling, drilling, and grinding. Difficulties arise from its elevated hardness and its inclination to work-harden, both of which can cause tool wear. Adequate lubrication and reduced cutting speeds are required to preserve tool life and produce smooth, precise finishes.
Al Summan Metals’ Stainless Steel 446 Hex Bars are widely applied in sectors where resistance to heat and corrosion is essential. They work perfectly for parts in furnaces, heat exchangers, chimneys, gas burners, and structural components exposed to high temperatures. In addition, they serve a vital function in chemical processing equipment, marine uses, and boiler systems subjected to corrosive and high-temperature environments. Combining mechanical strength, corrosion resistance, and dimensional stability, these hex bars deliver dependable performance, an extended service life, and efficiency across demanding industrial and engineering applications.
We supply products accompanied by both mill test certificates and third-party test certificates, guaranteeing the highest standards of quality and compliance.
