We guarantee durability, corrosion resistance, and dependability through the use of sophisticated manufacturing techniques and strict quality control procedures. Neil Metals is your trustworthy partner for Stainless Steel 446C solutions in India and abroad, supported by effective logistics and a customer-focused philosophy.
Especially at high temperatures, stainless steel 446C, a high-chromium ferritic alloy, exhibits exceptional resistance to oxidation and corrosion. In order to increase toughness, it usually contains a low carbon content, trace amounts of silicon, nickel, and molybdenum, and 23–27% chromium. Stainless Steel 446C Square Bars/Rods have good elongation and hardness levels, a yield strength of 275 MPa, and a tensile strength of about 485 MPa. These characteristics make it appropriate for uses where high temperatures and corrosive conditions are present, particularly in furnace and heat exchanger parts.

Yes, Stainless Steel 446 Square Bars are highly corrosion-resistant due to their high chromium content. They are particularly effective in resisting oxidation and scaling at elevated temperatures.
Yes, Stainless Steel 446 square bars can be welded using appropriate welding techniques like TIG or MIG welding. However, preheating and post-weld heat treatment may be required to minimize the risk of cracking and maintain structural integrity.
Yes, we provide stainless steel 446 square bars and rods in standard and customized dimensions and polishes to meet your specific project requirements. For more details mail us on sales@neilmetals.co.in
Industries that need to withstand oxidation, corrosion, and scaling at elevated temperatures frequently use stainless steel 446C square bars and rods. They are especially useful in petrochemical equipment, boiler baffles, heat exchangers, kiln linings and furnace parts. These rods are also perfect for incinerators and thermal processing units because of their remarkable heat resistance. They are appropriate for support elements in chemical plants and refineries due to their structural strength and longevity. Stainless steel 446C is also used in radiation tubes, recuperators, and exhaust systems, which makes it a popular option for demanding industrial settings.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
