Garg Steels, a well-known manufacturer and supplier located in Chennai, India, specializes in top-notch Stainless Steel 446 Flat Bars, celebrated for their exceptional heat and corrosion resistance. These bars are meticulously designed for high-temperature industrial uses, crafted with precision through advanced technology and high-quality raw materials. Stainless Steel 446 is a ferritic, non-heat-treatable alloy that boasts impressive resistance to oxidation, sulfidation, and various forms of scaling at elevated temperatures. Garg Steels offers these flat bars in a range of sizes and finishes, serving industries like power generation, heat treatment, petrochemicals, and furnace equipment manufacturing.
Stainless Steel 446 Flat Bars are composed of 23–27% chromium, 1.5% manganese, 0.2–0.5% silicon, and low carbon content (<0.20%), which grants them remarkable resistance to oxidation and corrosion at high temperatures. This ferritic stainless steel provides moderate tensile strength (approximately 485 MPa), yield strength (~275 MPa), and an elongation of 20%, along with outstanding scaling resistance up to 1100°C. While it may have lower ductility compared to austenitic grades, SS 446 maintains its mechanical integrity in thermal cycling environments, making it perfect for applications that demand heat resistance over long periods.
