Al Summan Metals, a well-regarded manufacturer and supplier based in Dubai, UAE, focuses on premium **Stainless Steel 446 Square Bars and Rods**. These products are known for their outstanding corrosion resistance, steadiness under high temperatures, and general durability. Manufactured with precision to meet international quality standards, they perform well in challenging conditions. Owing to their high chromium content and low carbon levels, 446 stainless steel delivers superb resistance to oxidation, scaling, and pitting, making it an ideal match for harsh industrial applications. Al Summan Metals’ 446 Square Bars and Rods are widely used in applications that demand enduring reliability, including chemical processing, power generation, marine engineering, and high-temperature equipment.
The composition of Stainless Steel 446 Square Bars and Rods mainly consists of 23–27% chromium combined with a low carbon level (≤0.2%), together with small quantities of manganese, silicon, and molybdenum. This distinctive mixture provides outstanding resistance to corrosion and oxidation at high temperatures. They offer remarkable mechanical characteristics, such as a tensile strength of 450–650 MPa, yield strength of 200–300 MPa, and elongation of 20–30%. The material is recognized for its solid hardness, toughness, and steadiness under elevated temperatures, which makes it well-suited for uses where both mechanical strength and heat resistance are essential.
