Inox Steel India is a trusted manufacturer, supplier, and exporter of Stainless Steel Bright Bars in grades 304, 316, 303, 410, and 431, supplying precision-engineered materials to industries across India, GCC countries, the Middle East, Africa, Europe, and the Americas. Our bright bars are developed for applications where tight dimensional tolerances, smooth surface finish, corrosion resistance, and consistent mechanical properties are essential for long-term performance.
Stainless steel bright bars from Inox Steel India are produced using controlled secondary processing such as cold drawing, peel turning, polishing, and centerless grinding. These processes enhance straightness, roundness, and surface integrity, making the bars ideal for high-speed CNC machining, rotating components, and critical mechanical assemblies.
Stainless Steel Bright Bars are cold-finished bars manufactured from hot-rolled stainless steel rods that undergo precision finishing operations to achieve improved surface quality and dimensional accuracy.
This controlled manufacturing process ensures that every stainless steel bright bar delivers repeatable machining performance, reduced tool wear, and excellent surface finish on final components.
SS 304 Bright Bars – General corrosion resistance, excellent formability, widely used in food, pharma, and structural components

At Inox Steel India, every bright bar is supplied with precision, traceability, and accountability. Whether you need SS 303 for CNC machining, SS 316 for marine service, or SS 431 for high-strength applications — we deliver the right material, on time.
SS 303 is preferred for high-speed CNC machining due to excellent machinability, while SS 304 is used for general-purpose machining. SS 316 contains molybdenum, offering superior resistance to chlorides and marine environments compared to SS 304. Bright bars are supplied in h8, h9, and h10 tolerances depending on size and finish. The standard HSN code is 7222 for stainless steel bars and rods. we supply custom cut lengths as per drawing to reduce machining time and material wastage. Inox Steel India regularly exports stainless steel bright bars to GCC, Africa, Europe, and the Americas. Which grade is best for CNC machining?
