Note: 1. Boom pipe wall thickness is 0.188”(4.5mm), Deck pipe wall thickness is 0.277”(7 mm)
2. The material is special alloy steel. Adopting high frequency and heat treatment techniques, the hardness comes up HRC58-62. The quenching thickness is 0.07"(1.8mm). Deeper heat penetration for longer wear .Single wall hardness which is comparable to double wall.
