FOB Shanghai: 635$/ton
q345qd steel is steel for highway bridges, which is a thick steel plate specially used for erecting railway lines or road and highway bridges.

As the thickness and hardness of SA573 Grade 58 carbon structural steel material increase, the tendency to crack at the cutting edge increases. In order to prevent the SA573 Grade 58 carbon structural steel material from cutting cracks, preheating should be carried out before SA573 Grade 58 carbon structural steel material cutting. Special attention should be paid to preheating to make the entire SA573 Grade 58 carbon structural steel material interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole SA573 Grade 58 carbon structural steel material cannot be preheated, the partial preheating method can be used instead.
