The weight of seamless steel pipe is only 1 / 5 of that of square steel. Seamless steel pipe corrosion resistance acid, alkali, salt and atmospheric environment corrosion, high temperature resistance, good impact and fatigue resistance, do not need regular maintenance. The effective service life of product EN10025-4 S420M steel more than 15 years.
The method of distinguishing manganese plate from common carbon steel plate, EN10025-4 S420M steel 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.
