Rupal Metals stands out as a reliable manufacturer and supplier of Stainless Steel 446 Rectangular Bars right in the heart of Delhi, India. They specialize in providing stainless steel solutions that can withstand high temperatures and resist corrosion, making them perfect for tough industrial applications. Stainless Steel 446 is a ferritic alloy celebrated for its remarkable ability to resist oxidation, sulfidation, and scaling, even at elevated temperatures. These rectangular bars are crafted with precision to meet the needs of industries like heat treatment, chemical processing, and thermal power. Rupal Metals is dedicated to quality and performance, offering SS 446 rectangular bars in a variety of sizes and custom specifications to cater to the diverse requirements of structural and engineering projects.
Stainless Steel 446 Rectangular Bars are primarily made up of Chromium (23–27%), with a low Carbon content (≤0.20%) and trace amounts of elements like Manganese, Silicon, and Molybdenum. This high chromium level gives it exceptional resistance to oxidation and sulfidation at temperatures up to 1100°C. SS 446 boasts a tensile strength of about 485 MPa, a yield strength of 275 MPa, and an elongation of roughly 20%. It’s magnetic, shows moderate ductility, and resists warping under thermal stress. While it’s not designed for cryogenic applications, it excels in thermal stability, corrosion resistance, and performance in harsh, high-temperature settings.

When selecting Stainless Steel 446 Rectangular Bars, consider factors like temperature resistance, corrosion resistance, and the specific environmental conditions. Additionally, ensure compatibility with the required mechanical properties and fabrication needs.
Stainless Steel 446 Rectangular Bars are not ideal for cryogenic applications due to their reduced toughness at low temperatures. For cryogenic use, materials with better low-temperature properties, like austenitic stainless steels, are recommended.
Stainless Steel 446 Rectangular Bars generally do not require additional corrosion protection coatings due to their inherent high corrosion resistance. However, in highly aggressive environments, coatings may be used for added protection.
Stainless Steel 446 Rectangular Bars find their place in various high-temperature service environments. You’ll often see them in furnace parts, burner assemblies, heat exchangers, and radiant tubes. In the chemical and petrochemical industries, SS 446 is utilized for structural components and supports that are exposed to hot corrosive gases or sulfur-rich environments. It’s perfect for boiler baffles, kiln linings, and incinerator internals. The rectangular shape not only provides strength but also structural support, making it ideal for fabricated frames, trays, and panels that need to withstand thermal fatigue. Its durability and resistance to oxidation make it a go-to choice for demanding applications.
