Is carbon steel 20#? Carbon steel means that alloy elements are not specially added into the steel, which is divided into ordinary carbon structural steel and high-quality carbon structural steel. The grades of ordinary carbon structural steel are Q195, Q215, Q235 and Q275. The grades of high quality carbon structural steels are: 10#, 20#, 45#, 15Mn, 20Mn, 25Mn, 30Mn, 35Mn, 40Mn, 45Mn, 65Mn, etc. It can be seen that ASTM A514 QT steel plate, 20# steel is carbon steel, but carbon steel means more than 20# steel.
According to GBT3077, 42CrMo steel chemical composition should be within the range (%): 42CrMo carbon content is 0.38-0.45 (C), Silicon content is 0.17-0.37 (Si), Manganese content is 0.50-0.80 (Mn), Chrome content is 0.90-1.20 (Cr), Molybdenum content is 0.15-0.25 (Mo). The high Cr content contrivutes to high strength of 42CrMo steel, with min. yield strength of 930 Mpa, and min. tensile strength of 1080 Mpa. The common heat treatment for ASTM A514 QT steel plate, 42CrMo steel is quenching and tempering.
NM400 wear plate is widely used in mining machinery, coal mining machinery, environmental protection machinery, engineering machinery and other product parts. Such as excavator, loader, bulldozer bucket plate, blade, side blade, crusher liner, etc.. NM400 wear plate is also commonly used as high-strength structural steel with yield strength ≥ 800MPa. The main function of NM400 wear plate is to provide protection in places or parts where wear resistance is required, so as to prolong the service life of the equipment.
