NM450 wearable steel plate
The chemical composition of NM450 wear-resistant steel plate mainly includes carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), copper (Cu), nickel (Ni), chromium (Cr), molybdenum (Mo) and other elements. Among them, C, Si, Mn, P, S are the main elements that affect the performance of these two steel plates. 0~2.30%, P content does not exceed 0.025%, S content does not exceed 0.015%. In addition, the contents of Cu, Ni, Cr, Mo and other elements are 1.50~2.00%, ≤0.30%, ≤1.60%, ≤0.30%, respectively, which can improve the strength and corrosion resistance of steel plates. 5-255.
