The difference between Q195 steel and 20# steel: Corten A hot rolled steel building material, Q195 steel is ordinary carbon structural steel, in which alloy elements are not specially added, and it is mainly used for construction and engineering structures. Q195 steel has low carbon and manganese content, low strength, good plasticity, high toughness, and good process performance and weldability. 20# steel is high-quality carbon structural steel. Alloy elements are not specially added to 20# steel, and it is mainly used in the manufacture of machine structures, and the amount of use is particularly large. 20# steel has higher strength than Q195 steel, good weldability, no temper brittleness, and its workability can be improved by water quenching.
As the thickness and hardness of Corten A hot rolled steel building material increase, the tendency to crack at the cutting edge increases. In order to prevent the Corten A hot rolled steel building material from cutting cracks, preheating should be carried out before Corten A hot rolled steel building material cutting. Special attention should be paid to preheating to make the entire Corten A hot rolled steel building material interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole Corten A hot rolled steel building material cannot be preheated, the partial preheating method can be used instead.
