Premium stainless steel 446 flat bars from Neil Metals, a well-known manufacturer and supplier with headquarters in Kolkata, India, are known for their exceptional resistance to oxidation and corrosion at elevated temperatures. Neil Metals’ years of experience in stainless steel solutions guarantee each batch’s exact measurements, flawless finishes, and exceptional mechanical qualities. Power plants, petrochemicals, and refineries are among the industries that use these flat bars, which are produced in accordance with international quality standards. Neil Metals is a reputable brand for long-lasting and highly effective stainless steel products in India and overseas, with a strong dedication to prompt delivery and client satisfaction.
Low carbon, trace amounts of silicon, manganese, and molybdenum, and 23–27% chromium make up stainless steel 446 flat bars. This ferritic stainless steel is very resistant to corrosion and oxidation at high temperatures. The material has an approximate yield strength of 275 MPa, a tensile strength of 485 MPa, and an elongation of 20%. It is not heat-hardenable and retains its structural integrity at high temperatures. It is also perfect for heat-intensive applications due to its high thermal conductivity and low thermal expansion.

Because of their resistance to oxidation and high temperatures, stainless steel 446 flat bars are frequently used in boiler components, kiln linings, heat exchangers and furnace parts. They are perfect for incinerators, exhaust systems, and thermal processing equipment in sectors like chemical processing, metallurgy, and power generation. The alloy is also appropriate for use in gas processing facilities and oil refineries due to its high resistance to sulfidation and scaling. To ensure performance and durability, 446 flat bars are also used in support brackets and structural elements that are subjected to high temperatures and corrosive conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
