Zoomlion S valve tube have two layers, outer is made of 16Mn, and inner layer is hard surfacing by VAUTID. With automatic welding technology, the inner wall is smooth and the impact force is small.
VAUTID 150 usd Tungsten carbide and low hydrogen sodium as main raw materials, and it has the characteristics of high hardness, good toughness, high temperature resistance and wear resistance. After hard surfacing, the HRC can be at least 63.
