Forged Square Bar C15 C35 C45 C60 S355J2G3 25CrMo4 42CrMo4

Forged bars usually have a denser structure than rolled steel (the result can be known by detecting the looseness of the material by the hot acid etching method). Through heat treatment, it is mainly a higher fatigue strength! Therefore, shaft parts with high requirements should be upset and drawn repeatedly to obtain better fatigue resistance.

Square Bar – catering for the demands of a wide range of industries Φ30-Φ1500mm bars, Flat and square on request.

Forged Round Bar Material we could provide
