The difference between Q195 steel and 20# steel: A709 Gr 50 bridge steel plate, 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.
Machining of A709 Gr 50 bridge steel plate, wear resistant steel plate: wear resistant steel plate has good cutting and shearing properties. During machining, the cutting tools and feeding speed should be used reasonably according to the hardness of steel plate. Common tools are made of high speed steel or cemented carbide steel, and carbide surface tools are required for grinding. Wear resistant steel plate can be welded to structural steel by arc welding.
