customer’s drawings.

Technical Data:

Surface roughness: Ra0.4 μm

Linearity of screw: 0.015mm/m

Depth of nitrided layer: 0.50~0.80mm

Nitrided hardness: 950~1100HV

Nitrided brittleness:less than grade one

Nitriding time: 160 hours above

Hard chrome plating of hardness after nitriding: ≥950HV

Depth of chrome plating layer: 0.03~0.10mm

Depth of bimetallic layer:≥3mm

Bimetallic hardness:HRC55-72

Function: based on vacuum heat treatment,high frequency quenching, nitriding treatment,hard chrome electroplating and bimetallic alloy spray welding.insure all screw barrels keep hardness from surface till core with torque resistance,high hard-wearing,strong flowability and work under high temperature with resistant high density adhesion and resist high corrosion.
