Hardness after quenching: HB280-320
Hardness after nitride :> HV950
Nitride depth: 0.5mm-0.8mm
3. Bimetallic screw barrel
A. The flights of screw are grooved and bimetallic layer is coated by spray wielding method.
Nickel based alloy powder is applied.
B. SKD 61 is a kind of steel imported from Japan which is even more durable than normal bimetallic barrel. We use SKD steel to the wearing part of barrel as shown in the below picture.
