Special Grades Meet Stringent Requirements
Among the many alloy steel round bar grades, S45C steel round bar, as a representative of medium carbon alloy steel, is widely used in the manufacture of shafts, gears, and other mechanical parts due to its excellent machinability and hardenability. For more demanding transmission systems, gear steel round bars, with their uniform hardness and fatigue resistance, are ideal for core components such as gearboxes and reducers.

The 20, 37Mn5, and GCr15 grade tube billet round bars offered by ZZ Group are a typical example of the industrial value of alloy steel round bars. These precisely designed round bar products are optimized for the seamless steel pipe piercing process, exhibiting excellent forming stability and microstructure uniformity in subsequent processing, helping manufacturers produce high-quality seamless pipes.
