High-end stainless steel bright bars and rods are the speciality of Neil Metals, a well-known manufacturer and supplier with headquarters in Kolkata, India. Using sophisticated cold drawing and polishing techniques, our bright bars and rods are known for their exceptional surface finish, dimensional accuracy, and reliable mechanical qualities. They satisfy a variety of industrial needs in the engineering, fabrication, automotive, and construction sectors and come in a broad range of grades, sizes, and shapes. Neil Metals is dedicated to providing durability, corrosion resistance, and customer satisfaction with each supply of high-performance stainless steel products that satisfy international standards, both in India and in international markets.
Depending on the grade (e.g., 304, 316, 410), stainless steel bright bars and rods are usually made of chromium (16–20%), nickel (8–14%), and additional alloying elements like molybdenum, manganese, and carbon. With a tensile strength of 500–750 MPa and a high yield strength, these cold-finished bars have exceptional mechanical strength. The bright, smooth surface finish improves accuracy and resistance to corrosion. They are appropriate for high-stress situations because they have good hardness, weldability, and machinability. For crucial applications, the manufacturing process guarantees consistent cross-sections and enhanced surface quality.
