ST52 forged round bar With Black/Turned/Grinded
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.
