As the thickness and hardness of JIS SM400C plates increase, the tendency to crack at the cutting edge increases. In order to prevent the JIS SM400C plates from cutting cracks, preheating should be carried out before JIS SM400C plates cutting. Special attention should be paid to preheating to make the entire JIS SM400C plates interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole JIS SM400C plates cannot be preheated, the partial preheating method can be used instead.
