S355J2G3 Mechanical Property

S355J2 forged round bar

S355J2G3N is a low carbon structural steel grade often used for application which require better mechanical properties than that of S275 and S235 grade. It is generally supplied in a normalized condition which is widely used in engineering and construction industries.

Fuhong steel have tested S355J2G3N mechanical property in the lab according to customer’s requirements.
