Al Summan Metals, a leading manufacturer and supplier based in Dubai, UAE, focuses on premium **Stainless Steel 446 Hollow Bars**. These bars are renowned for their outstanding corrosion resistance, notable strength under high temperatures, and all-around durability. Produced with precision and advanced technology, they meet international quality standards, guaranteeing dependable performance even in demanding industrial environments. Owing to their elevated chromium and reduced carbon content, 446 stainless steel stands out in fighting oxidation, scaling, and pitting, even under intense heat. Al Summan Metals’ 446 Hollow Bars are ideal for a wide range of uses, such as chemical processing, marine settings, power generation, and high-temperature applications, delivering structural integrity, enduring reliability, and superior operational efficiency.
These 446 Stainless Steel Hollow Bars generally hold 23–27% chromium, with carbon levels at ≤0.2%, plus small quantities of manganese, silicon, and molybdenum. This distinctive composition ensures outstanding resistance to corrosion and oxidation, along with steadiness under high temperatures. They deliver remarkable mechanical qualities, such as tensile strength in the 450–650 MPa range, yield strength from 200–300 MPa, and elongation of 20–30%. The material additionally provides solid hardness, toughness, and durability, which makes it well-suited for settings that are high-stress, high-temperature, and corrosive.

SS 446 hollow bars usually consist of 23-27% chromium, 1-2% silicon, 0.75% manganese, and minor quantities of carbon, phosphorus, sulfur, and nickel, delivering outstanding resistance to high-temperature oxidation and corrosion.
SS 446 hollow bars offer several major advantages, such as outstanding resistance to high-temperature oxidation, exceptional corrosion resistance, long-lasting performance in demanding conditions, and robust strength at high temperatures, which makes them well-suited for furnace and chemical processing uses.
Al Summan Metals’ Stainless Steel 446 Hollow Bars are widely applied across industries requiring parts that withstand elevated temperatures and corrosion. They work especially well for furnace components, heat exchangers, chimneys, and gas burners. In addition, they serve in chemical processing equipment, boiler tubes, and marine settings exposed to harsh, high-temperature conditions. The hollow construction cuts weight while preserving strength, giving these bars flexibility across structural, mechanical, and fluid-handling uses. Combining corrosion resistance, mechanical strength, and accurate dimensions, they deliver a long service life and reliable performance in tough environments.
We offer products supplied with both mill test certificates and third-party test certificates, guaranteeing the highest levels of quality and compliance.
