It is mainly used for cold forming. With the alloy galvanized coating, the recommended nominal coating weight is 30/30, 40/40, 50/50, 60/60, 75/75, 90/90g/m².

q355gnh steel angle, 30CrMnSiA steel has good machinability, small processing deformation and good fatigue resistance. If 30CrMnSiA steel is used to make a tool, it is processed to the tool shape by rough machining. Mill the cutting edge with a cemented carbide milling cutter and polish it with a polishing machine. There should be no problem for the surface roughness reaching 3.2. 30CrMnSiA steel has high strength, sufficient toughness and good hardenability after quenching and tempering. After quenching and tempering, 30CrMnSiA steel can be used for grinding wheel shafts, gears and sprockets.

q355gnh steel angle, S355j2g3 steel plate is a kind of main atmospheric corrosion-resistant steel, s355j2g1w steel plate is a kind of weathering structural steel, its mechanical properties are similar to s355j2g2. By adding CR, Cu and Ni, the oxide layer is firmly attached to the workpiece surface. This oxide layer prevents further corrosion of the steel.
