Powder
Steel: The mechanical specifications of powder steel are better than
tool steel. The heat treatment stability is also better than tool steel;
furthermore, it is easier to estimate the deformation after heat
treatment. Due to the better hardness, toughness and it can temper in
the high temperature, so powder material is suitable for PVD coating.
Tool Steel: Because of include high percentage of C and Cr, tool steel
has good anti-abrasion performance and also good toughness performance.
Mo and V provide the tool steel has high impact and good heat treatment
stability.
Stainless Steel: High percentage of Cr provides
stainless steel has outstanding anti- corrosive. The hardness can
achieve to over HV 1000 after plasma nitride.

Fully Coat screw is use HP/HVOF (High pressure/ High velocity Oxygen Fuel) technology to coat the alloy powder on the entire screw surface.
It means alloy powder spraying is under high pressure and high velocity (3-4 times sonic). The adhesive force is over 10000PSI, and the powder density can achieve to 99.8%.

Plasma is a gas which is heated to an extremely high temperature and ionized so that it becomes electrically conductive.
The plasma transfer arc welding process uses this plasma to transfer an electric arc to the screw flight. The metal to be welded is melted by the intense heat of the arc and fuses together.
