NM450 High strength abrasion resistant steel plates

NM450 steel Size:
Thickness: 3mm to130mm
Width: 1450mm to 4050mm,
Length: 3000mm to 15000mm

NM450 is an abrasion resistant plate with a hardness of 450 HBW, intended for applications where demands are imposed on abrasion resistance in combination with good cold bending properties. High strength abrasion resistant steel plates GB/T709 NM400 offers very good weldability.
