Al Summan Metals, a first-rate manufacturer and supplier based in Dubai, UAE, focuses on premium-quality **Stainless Steel 446 Rectangular Bars**. These bars are renowned for their exceptional corrosion resistance, notable strength under high temperatures, and overall durability. Made with precision and subject to rigorous quality control, they comply with international standards, guaranteeing reliable performance even in demanding industrial environments. Owing to their high chromium and low carbon content, 446 stainless steel delivers superb protection against pitting, scaling, and oxidation, even under extreme heat. Al Summan Metals’ 446 Rectangular Bars serve a range of industries, including chemical, marine, power generation, and high-temperature applications, offering structural integrity, enduring reliability, and exceptional operational efficiency.
These Stainless Steel 446 Rectangular Bars consist primarily of 23–27% chromium, with a carbon content of ≤0.2%, together with small quantities of manganese, silicon, and molybdenum. This distinctive composition provides them with outstanding corrosion resistance and remarkable stability against high-temperature oxidation. They feature notable mechanical properties, such as a tensile strength spanning 450–650 MPa, yield strength of 200–300 MPa, and elongation of 20–30%. The material additionally delivers good hardness, toughness, and thermal stability, making it ideal for applications demanding both mechanical strength and high-temperature resistance.

When choosing Stainless Steel 446 Rectangular Bars, take into account aspects such as temperature resistance, corrosion resistance, and the particular environmental conditions. In addition, verify compatibility with the necessary mechanical properties and fabrication requirements.
Because of their diminished toughness at low temperatures, Stainless Steel 446 Rectangular Bars are not well suited for cryogenic applications. When cryogenic conditions are involved, it is advisable to use materials that offer superior low-temperature performance, such as austenitic stainless steels.
Stainless Steel 446 Rectangular Bars typically do not need extra anti-corrosion coatings because of their naturally strong resistance to corrosion. That said, in extremely harsh conditions, coatings can be applied for enhanced protection.
Al Summan Metals’ Stainless Steel 446 Rectangular Bars are widely used across industries that require components able to endure elevated temperatures and corrosion. They are especially suitable for furnace parts, heat exchangers, chimney linings, and gas burners. Additionally, they find application in chemical processing equipment, boiler components, and marine settings exposed to severe and high-temperature environments. Their blend of mechanical strength, high-temperature stability, and corrosion resistance guarantees that these bars provide extended service life, dependable performance, and operational efficiency in demanding industrial and engineering applications.
We supply products that arrive with both mill test certificates and third-party test certificates, guaranteeing the highest standards of quality and compliance.
