Neil Metals is a well-known Indian manufacturer and supplier company based in Kolkata, India, and it delivers high-quality Stainless Steel 347 Rectangular Bars according to the stringent industrial demands. With a primary emphasis on product reliability and customer satisfaction, the company supplies stainless steel bars that are highly known for their great performance in corrosive and high-temperature applications. These bars are manufactured by adopting advanced manufacturing processes and strict quality checks to provide better durability, stability, and resistance against oxidation. Neil Metals supplies to a vast range of industries such as petrochemical, aerospace, power generation, and food processing with a guaranteed timely delivery and international standards compliance for all their stainless steel products.
Rectangular Bars of Stainless Steel 347 are stabilized austenitic stainless steel products that consist mainly of 17–19% Chromium and 9–13% Nickel, with Columbium (Niobium) added to avoid carbide precipitation. The alloy further contains components like Manganese, Silicon, Phosphorus, and Sulfur in limited proportion. These bars have superb mechanical strength with a usual tensile strength of 515 MPa, yield strength of 205 MPa, and elongation of 40%. SS 347 Rectangular Bars possess excellent creep strength, corrosion resistance, and weldability, particularly in high-temperature environments where intergranular corrosion is possible.

Stainless Steel 347 Rectangular Bars are extensively used in applications where high-temperature strength and corrosion resistance are essential. Their stabilization with Columbium renders them appropriate for applications subject to repeated thermal cycling and exposure to severe oxidizing environments. Some of the common applications are furnace components, heat exchangers, chemical tanks, boiler shells, and exhaust systems in refineries and thermal power plants. They are also used in food processing, aerospace, and pharmaceutical equipment on account of their surface cleanliness finish and scaling resistance. These bars provide structural integrity and long-term performance under high-stress and corrosive service conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
