Sahil Metals stands out as a top manufacturer and supplier in Riyadh, Saudi Arabia, offering high-quality Stainless Steel 446 Hex Bars that are celebrated for their durability, strength, and resistance to high-temperature oxidation. This ferritic stainless steel grade boasts excellent scaling resistance, making SS 446 Hex Bars perfect for tough environments where extreme heat and corrosive conditions are the norm. At Sahil Metals, we ensure our hex bars are crafted with precision to meet international standards, guaranteeing dimensional accuracy and a long service life. These bars find their place in various industries, including power generation, petrochemical, heat treatment, and furnace manufacturing, where reliable and efficient performance is crucial.
Stainless Steel 446 Hex Bars are made up of high chromium (around 23–27%) with low carbon content, along with small amounts of molybdenum, silicon, and manganese. This unique blend gives them remarkable resistance to oxidation, sulfidation, and scaling at temperatures reaching up to 1100°C. SS 446 maintains good strength even at elevated temperatures, offers moderate toughness, and excels in resisting corrosion in harsh environments. With a Brinell hardness of about 150–200 HB and tensile strength ranging from 450–550 MPa, its ferritic structure ensures stability, low creep, and enhanced thermal fatigue resistance.

Stainless Steel 446 Hex Bars are extensively used in industries that require exceptional resistance to heat, oxidation, and corrosive conditions. They play a vital role in furnace components, heat exchanger tubes, burners, and boiler parts. In petrochemical facilities, they are essential for processing equipment that comes into contact with hot gases and corrosive chemicals. Power plants utilize them in superheater and reheater sections. Moreover, SS 446 Hex Bars are found in kiln linings, gas turbines, and thermal processing equipment. Their outstanding scaling resistance guarantees durability and a long service life, even in the most extreme industrial settings.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
