As the thickness and hardness of A709 grade 50 carbon steel plate sheet increase, the tendency to crack at the cutting edge increases. In order to prevent the A709 grade 50 carbon steel plate sheet from cutting cracks, preheating should be carried out before A709 grade 50 carbon steel plate sheet cutting. Special attention should be paid to preheating to make the entire A709 grade 50 carbon steel plate sheet interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole A709 grade 50 carbon steel plate sheet cannot be preheated, the partial preheating method can be used instead.

The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents.
