outstanding features of bimetallic screw and barrel:
1)hardness hrc50-65
2)outstanding corrosion-resistance.
3)hardness layer reaches 1.5 mm 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.
