Alloy Steel Round Bar

2mm, 3mm, 6mm 42crmo4 Bar, Manufacturer of SAE 4140 Rod

Alloy Steel Round Bar is made up of different material grades such as A-182, F5, F9, F11, F12, F22 & F91. These are made up of various metal alloys that are corrosion resistant and strong. Navstar Steel is a leading supplier and manufacturer of these Alloy Steel Round Bar products. There are different compositions to the alloys and different specifications and standards.

Hot Rolled Alloy Steel Round Bars, Cold Drawn Alloy Steel 42crmo4 Round Bar, Alloy Steel Bright Bars Manufacturers In India

The bars come under ASTM, ASME and API standards with specifications in ASTM, ASME, SA 182, ASTM 276 and ASME SA 276. The bars range from 4mm to 350mm in diameter in general. The 42crmo4 Bar has carbon, manganese, chromium, molybdenum, phosphorus and sulfur in its composition. They are corrosion resistant and strong with a minimum tensile strength range of 850MPa to 1000MPa. It is also resistant to wearing. The SAE 4140 Rod is made up of carbon, silicon, nickel, phosphorus, manganese, chromium and sulfur in its composition.


It has 80ksi minimum yield strength and 100ksi minimum tensile strength. It can come in annealed, hardened and tempered and precipitation hardened conditions. It is used in applications that demand resistance and rigidity. The Hot Rolled Alloy Steel Round Bars are used in brake dies, trim dies, bolsters, gears, stubs, reamer bodies, tool holders, chain links, fixtures, valves, spindles, couplings and many other applications and tools. The Alloy Steel 42crmo4 Round Bar and other types of alloy steel bars are preferred because of their cost effectiveness over high alloy metals and commercially pure expensive metal bars. As one of the leading Alloy Steel Bright Bars Manufacturers In India we supply all types of these bars in all grades and specifications. Please contact us for more information and pricing of these materials.
