Q345R steel is common low alloy steel, which is commonly used for boiler and pressure vessel. The delivery status includes hot rolling or normalizing. Q345R steel yield strength is 265-345MPa, tensile strength is 510-640MPa, elongation is greater than 21%, and zero degree V-shaped impact energy is greater than 34J. Q345R steel standard is GB713. Q345R steel has good comprehensive mechanical and technological properties. The content of equivalent of P355GH steel phosphorus and sulfur of Q345R steel is slightly lower than that of low alloy high strength steel plate.

equivalent of p355gh steel, 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.
