Sahil Metals stands out as a top manufacturer and supplier in Riyadh, Saudi Arabia, offering high-quality Stainless Steel 446 Flat Bars designed for tough industrial applications. SS 446 is a ferritic stainless steel grade known for its remarkable resistance to oxidation, sulfidation, and scaling, even at high temperatures. At Sahil Metals, we take pride in crafting our flat bars with precision, ensuring they have accurate dimensions, a smooth surface finish, and impressive durability. Built to thrive in extreme conditions, our Stainless Steel 446 Flat Bars are widely used in power plants, petrochemical facilities, furnace equipment, and thermal processing industries, delivering unmatched reliability and performance in challenging environments.
Stainless Steel 446 Flat Bars are made up of 23–27% chromium, with low carbon content and trace amounts of elements like molybdenum, silicon, and manganese. This high chromium level boosts their resistance to oxidation at elevated temperatures and in corrosive settings. The material showcases a tensile strength ranging from 450–550 MPa, a yield strength of around 275 MPa, and a Brinell hardness between 150–200 HB. SS 446 Flat Bars maintain their structural stability and mechanical integrity even at high temperatures, offering excellent thermal fatigue resistance, moderate toughness, and good corrosion resistance, making them ideal for demanding and continuous industrial operations.

Stainless Steel 446 Flat Bars find extensive applications in industries that need materials capable of enduring extreme heat and corrosive conditions. They are often used in furnace parts, kiln linings, boiler components, and heat exchanger systems. In petrochemical plants, you’ll find them in reactors, piping, and equipment that come into contact with hot corrosive gases. Power generation facilities depend on them for superheater and reheater components. Additionally, they are utilized in burners, thermal processing systems, and incinerator parts.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
