Double alloy screw

Zhoushan FuxiangDouble alloy screwIntroducing *'s melt spray welding and centrifugal casting technology and equipment, the imported alloy powder is directly sprayed onto the surface of the screw and the inner hole of the material pipe with high quality and high speed in production. The alloy depth can reach 2.5mm~5mm or more, and the density of the alloy surface is as high as 98%~99.5%. At the same time, the screw temperature is controlled at a low temperature throughout the production process to prevent thermal deformation and brittleness. The adhesion strength of the alloy powder exceeds 10000psi. Therefore, under high torque use, the double alloy screw produced by Zhoushan Fuxiang has *'s characteristics of wear resistance, corrosion resistance, and bending resistance, which can provide services for factories using engineering plastics and corrosive plastics. In addition, our company's dual alloy pipes are divided into three grades: A, B, and C. The alloy contains 40% tungsten nitride; B-class alloy containing 25% tungsten nitride; C-grade alloy contains 9.5% tungsten nitride. All of its materials are made of imported SKD61 high-quality alloy steel.
