Alloy Steel Round Bar, Alloy Steel Bar, SAE 4140 Rod, CrMo Round Bar, Chrome Moly Rods, A182 Alloy Steel Round Bar Supplier in Mumbai, India.
Bhansali Exports is a trusted manufacturer and supplier of Alloy Steel Round Bar in Mumbai, India. An alloy steel round bar is a solid, round metal bar with added elements to increase strength and wear life. These bars are available in several grades, including A182 F5, F9, F11, F12, F22, and F91. Each grade suits a different pressure and temperature range. The product follows ASTM A182, ASTM A276, ASME SA182, ASME SA276, and API standards. As an alloy steel round bar supplier we offer sizes range from 4 mm to 350 mm in diameter, and each bar meets strict quality norms for strength and long service life.
Alloy steel round bars contain carbon, manganese, chromium, molybdenum, and small amounts of phosphorus and sulfur. Some grades also include nickel and silicon for added strength. This mix improves hardness, wear resistance, and heat strength. Tensile strength can reach up to 850–1000 MPa in grades like 42CrMo4. SAE 4140 offers high yield and tensile strength for load-bearing parts. These bars handle stress, impact, and high pressure with ease. Common uses include gears, shafts, bolts, spindles, valves, couplings, and tool holders. Many industries rely on these bars for power plants, oil and gas units, and heavy machines.

Our manufacturing process begins with the selection of high-quality raw materials. The steel is melted in electric furnaces at controlled temperatures. The hot rolling process forms the round shape to the appropriate size by subjecting it to heat treatments such as annealing, quenching and tempering. The bright bars go through cold drawing to provide exact size control and a flawless finish. We ensure that each bar is evaluated for strength, hardness and chemical balance. We use wooden boxes or protective coverings to prevent them from damage during shipping and are clearly labelled so that they may be easily tracked.
