Q235B carbon steel plate

Mild steel plate  is one kind plain carbon steel .The carbon content of them  is less than 0.25% , because of its low strength, low hardness and soft, it is also called soft steel. It includes most of the ordinary carbon structural steel and a part of the high quality carbon structural steel, mostly not by heat treatment for engineering structural parts, some by carburizing and other heat treatment for the requirements of wear-resistant mechanical parts. Q235B  carbon steel plate  is a low carbon structural steel, it be used for welding, bolt connection, riveting structure. as Buildings, Bridges, ships, vehicle's structure, manufacturing a variety of tools and cutters, mould and measuring tool, etc. How strong is Q235 steel?
