S235JR is a European standard non-alloy structural steel, which is equivalent to the national standard Q235B, that is, carbon structural steel with low carbon content, which is used for welding, bolting and riveting structures. S235JR carbon structural steel, the carbon content is about 0.05% to 0.70%, and individual can be as high as 0.90%. It can be divided into ordinary carbon structural steel and high-quality carbon structural steel.

Application range of S235JR carbon structural steel
S235JR carbon structural steel is often rolled into wire rod or round steel, square steel, flat steel, Angle steel, I-beam, Channel steel, window frame steel, etc., and medium and thick steel plates. S235JR carbon structural steel is mainly used in railways, bridges, various construction projects, manufacturing various metal components bearing static load and unimportant mechanical parts and general welding parts that do not require heat treatment. C, D grade steel can also be used as some professional steel.
