Located in Kolkata, India, Neil Metals is a well-known manufacturer and supplier that specialises in providing customers in a variety of industries with premium stainless steel 446 hexagon bars. Our SS 446 Hex Bars, which are well-known for their exceptional performance and precision engineering, are produced with the use of cutting-edge methods and strict quality controls to guarantee strength, dependability, and durability. These bars have outstanding resistance to oxidation and sulfidation and are specifically made for high-temperature and corrosive environments. Neil Metals is the go-to supplier for stainless steel products in India and abroad thanks to our robust distribution network, customer-focused service, and prompt delivery and reliable quality.
With a low carbon content and trace amounts of silicon, manganese, and molybdenum, stainless steel 446 is a high-chromium ferritic stainless steel that has a chromium content of 23–27%. It is perfect for high-heat applications because of its exceptional resistance to oxidation and sulfidation at high temperatures. The alloy has outstanding creep strength, a yield strength of about 275 MPa, and a tensile strength of about 485 MPa. It is a dependable option for parts subjected to extended heat and corrosion because of its remarkable performance in thermally aggressive environments, despite its limited toughness at low temperatures.

Industries that need to withstand high temperatures and corrosive environments frequently use stainless steel 446 hexagon bars. These hex bars are frequently used to fabricate boiler baffles, radiant tubes, furnace components, and incinerator parts. They are perfect for thermal processing equipment in the steel, cement, and petrochemical industries due to their exceptional scaling resistance up to 1100°C. They are also used in gas burners, kilns, heat exchangers and exhaust systems. Because of their hexagonal shape, these bars provide both structural integrity and operational longevity under harsh conditions, making them appropriate for applications requiring precise machining and torque-resistant assemblies.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
