YUYAO RUIFENG HYDRAULIC CO., LTD.Base Info
Description
Product FeaturesBrand JINYI Product Name Bimetallic Screw Base Material 38CrMoAlA High-quality Alloy Structural Steel Bimetallic Material JYS01(Ni,Cr,Si), JYS02(Ni,Cr,W), JYS03(Co,Cr,W) Quenching and Tempering Hardness HB260-280 Nitriding Hardness HV950±50 Nitride Layer Depth & Hardness 0.4-0.6mm , 56-60HRC Brittleness ≤2 Surface Finish Ra0.04 Scope of Application Suitable Recycling & Engineering Plastics & < 20% reinfored additives & corrosive plastic 
Bimetallic Screw
PTA (Plasma Transferred Arc) automatic alloy spaying is a newly applied technology, especially for precise requirement of screws. Comparing to traditional manual alloy spraying, PTA has better performance with the stability and outlook of screws.
Technical Parameters
Product Name : Bimetallic Screw
Material : JYN1 + JYS Series Alloy
