St52 Hot Forged Steel Round Bars With Black / Turned / Grinded Surface

ST52 forged round bar With Black/Turned/Grinded

APPLICATIONS:

The steel is suited to applications where high surface pressures exist and friction is to be resisted as in the case of severely loaded gears, axles and pinions.

It is used extensively in most industry sectors for applications requiring higher tensile strength.

Process: EAF+LF+VOD+ Forged+Heat Treatment(optional)

The bars are high in quality and used for making OEM Auto components and making machinery. Carbon Steel ST 52 Round Bar has high tensile strength with higher strength. To produce high tensile properties this carbon-manganese grade is worked and is often used in the automotive industry. Steel round bars used in various engineering applications, bright bars, and structural bars. The various testsis performed to check the quality of the product and packaging is done in a proper way to maintain the quality of the product.
