As the thickness and hardness of Comparison of S355NL and SA572 Grade 55 steel increase, the tendency to crack at the cutting edge increases. In order to prevent the Comparison of S355NL and SA572 Grade 55 steel from cutting cracks, preheating should be carried out before Comparison of S355NL and SA572 Grade 55 steel cutting. Special attention should be paid to preheating to make the entire Comparison of S355NL and SA572 Grade 55 steel interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole Comparison of S355NL and SA572 Grade 55 steel cannot be preheated, the partial preheating method can be used instead.
