S235JR Flat Bar

 

 

S235JR is a European standard non-alloy structural steel, equivalent to the national standard Q235B, which is a carbon structural steel with lower carbon content and is used in many welding, bolted and riveted structures. Carbon structural steel has a carbon content of about 0.05% to 0.70%, and can be as high as 0.90% in some cases. It can be divided into two categories: ordinary carbon structural steel and high-quality carbon structural steel.

 

S235JR flat bar has extremely stable performance, easy cutting and welding and relatively low requirements on steel plate quality. It is often used in mining machinery, engineering machinery, metallurgical machinery, or for welding of ordinary structural parts, high-rise building materials, etc. It is often used in mining machinery, engineering machinery, metallurgical machinery, or in welding of ordinary structural parts, high-rise building materials, etc.
