Outstanding Features of Bimetallic Screw and Barrel:
1)Hardness HRC50-65
2)Outstanding corrosion-resistance.
3)Hardness layer reaches 1.5 m/m thickness.Hardness does not decrease with depth.
4)Hardness does not decrease under normal temperature.
5)Abrsion resistance / wear resistance on the hardened layer is 2~3 times higher than that treated by conventional heat treatment.
