Plate thickness below 4 mm only after special agreement
CEV = C+Mn/6+(Cr+Mo+V)/5+(Cu+Ni)/15
CET = C + （Mn+Mo）/10+( Cr+ Cu)/20+ Ni/40

With high speed development of technology and modern industry, manufactures are more likely to use high strength abrasion resistance steel plates so as to reduce the economic lost brought by part wear.

NM450 under GB/T24186 and Hardox 450 are mainly used for charging cranes, excavators, dumpers, conveyers, trucks, breaking and cutting tools, waste disposal and recovery equipment.
