20CrNi4WMoV pipe piercing Mandrel head is a high-performance tool steel used for manufacturing piercing mandrels. It has high strength, high toughness, and good wear resistance.
20CrNi4WMoV is a low carbon alloy structural steel, chemical composition includes C, Si, Mn, P, S, Cr, Ni, Mo, V. Grade 20CrNi4WMoV has quite good properties as high hardness, high tensile, good wear resistance and anti- corrosion. This material is very widely applied in manufacturing machinery, auto parts, shipbuildings.
Hengdisheng technic group is now under discovering and designing better and better heat-treatment procedures to improve and develop 20CrNi4WMoV alloy steel performances in its application industries.
