Based in the heart of Manama, Bahrain, Junaid Metals is your trusted partner for premium stainless steel solutions, where our dedication to quality and reliability meets the demanding needs of the region’s industries. We take pride in supplying the robust Stainless Steel 446 Hollow Bar, a material specifically engineered to excel in high-temperature and highly corrosive environments. This product is a testament to our commitment to providing components that offer exceptional durability and long-term performance for the most challenging applications.
The composition of Stainless Steel 446 is distinguished by its high chromium content, which provides a powerful shield against oxidation and corrosion, particularly at elevated temperatures. This alloy delivers impressive mechanical strength and retains its integrity even when exposed to intense heat, making it a remarkably resilient choice. Its inherent toughness ensures it can withstand significant stress, offering a reliable performance profile that is crucial for components operating under demanding thermal and mechanical loads.

SS 446 hollow bars typically contain 23-27% chromium, 1-2% silicon, 0.75% manganese, and small amounts of carbon, phosphorus, sulfur, and nickel, providing excellent resistance to high-temperature oxidation and corrosion.
Key benefits of SS 446 hollow bars include excellent high-temperature oxidation resistance, superior corrosion resistance, durability in harsh environments, and strength at elevated temperatures, making them ideal for furnace and chemical processing applications.
The unique properties of the 446 Hollow Bar make it an indispensable material for critical high-temperature applications. It is extensively used in the manufacturing of furnace parts, heat treatment fixtures, and essential components within industrial heating systems. Furthermore, its exceptional resistance to sulfidation makes it a preferred choice in the petrochemical industry. You will also find it perfectly suited for thermal processing equipment and as a robust structural element in environments where other steels would rapidly deteriorate.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
