SA709 Gr 50 carbon steel plate sheet made in China for sale
Structural steel for construction is used to build boilers, ships, bridges, workshops and other building materials. This kind of steel usually needs welding construction, so it is generally low carbon steel with carbon content less than 0.25%, which is mostly used in hot rolling or normalizing state. SA709 Gr 50 carbon steel plate sheet, Structural steel for machinery is used for manufacturing machines or mechanical parts. This kind of steel is often used after carburizing or quenching and tempering. The steel used for carburizing is low carbon steel with carbon content of 0.1% ~ 0.3%. Steel used for quenching and tempering refers to medium carbon steel with carbon content of 0.3% ~ 0.6%.

As the thickness and hardness of SA709 Gr 50 carbon steel plate sheet increase, the tendency to crack at the cutting edge increases. In order to prevent the SA709 Gr 50 carbon steel plate sheet from cutting cracks, preheating should be carried out before SA709 Gr 50 carbon steel plate sheet cutting. Special attention should be paid to preheating to make the entire SA709 Gr 50 carbon steel plate sheet interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole SA709 Gr 50 carbon steel plate sheet cannot be preheated, the partial preheating method can be used instead.
