Factory direct sell 5.2mm thick coil nm400 wear resistant plate sheets

The method of distinguishing manganese plate from common carbon steel plate, NM400 wear resistant plate 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.

Chemical composition of 65Mn steel: C 0.62-0.70, Si 0.17-0.37, Mn 0.90-1.20, Cr ≤ 0.25, Ni ≤ 0.30, Cu ≤ 0.25. 65Mn steel mechanical properties: tensile strength: ≥735 Mpa, yield strength: ≥430 Mpa, elongation after fracture: ≥9%, reduction of area: 30%, impact absorbed energy: no impact. NM400 wear resistant plate, 65Mn steel has high strength, high hardenability, less decarburization tendency, overheat sensitivity, easy to produce quenching cracks and temper brittleness. 65Mn steel is used for making various flat and round springs, leaf springs, spring rings, valve springs, steel wire cold coil springs, clutch springs of light trucks and cars.
