S235JR, S235J0 and S235J2 steel comparison

S235JR, S235J0 and S235J2 steel comparison

Posted:2021-01-07 11:36:31

S235JR steel is a European standard carbon structural steel plate, equivalent to the Chinese steel grade Q235B. It is used for welding, bolting, and riveting structures. There are S235 series steel plates, S235JR, S235J0 steel and S235J2. Below are the main comparison among S235JR, S235J0 and S235J2 steel in chemical composition (Table 1) and mechanical properties (Table 2).
