The method of distinguishing manganese plate from common carbon steel plate, nm300 wear resistance sheet is as follows:(1) Check the spray labelWhether it is manganese plate or common carbon steel plate, it has its own factory spray mark, just check it;(2)Listen to the cutting soundThe cutting sound of manganese plate is relatively clear and crisp, while that of common carbon steel plate is not clear and crisp, and the manganese plate will fall off as soon as it is cut;(3) Look at the polishing sparksLook at the amount of sparks on the surface during polishing. The more sparks and forks are manganese plates, and the lesser ones are common carbon steel plates;(4) Check the material certificateGenerally, the material certificate will clearly indicate what material it is, just check it.
The yield strength of Q690D steel plate is 690 Mpa and the impact temperature is - 20℃. nm300 wear resistance sheet, Q690D steel plate has high strength, good plasticity and toughness, good weldability and good cold and hot performance. Q690D steel plate is mainly used to manufacture various large engineering structural components and construction machinery. Because of its high strength and good toughness, Q690D steel plate can reduce the self weight of components and meet the requirements of large-scale and lightweight engineering components and equipment under the condition of ensuring strength, stiffness and reliability.
The main applications of normalizing are as follows:① For low carbon steel, nm300 wear resistance sheet. The hardness of low carbon steel after normalizing is slightly higher than that after annealing, and the toughness is also better, so normalizing can be used as the pretreatment of cutting.② For medium carbon steel, normalizing can be used as the final heat treatment instead of quenching and tempering treatment, or as the preparation treatment before surface quenching by induction heating.③ Normalizing can be used in tool steel, bearing steel, carburizing steel and so on, which can eliminate or inhibit the formation of network carbide, thus obtaining the good microstructure needed for spheroidizing annealing.④ Normalizing can refine the cast structure and improve the machinability of steel castings.
