Process:
 
Wire: Material preparation→melting→re-melting→forging→hot rolling→heat treatment→surface treatment→drawing(rolling)→finish heat treatment→inspection→package→warehouse
 
Strip:Material preparation→melting(vacuum,medium frequency)→electroslag→lathe-forging→planing→hot rolling→annealing→polish by high pressurewater→rolling→degrease→annealing→welding→rolling→edge shearing→annealing→slitting→inspection→package
 
when you order wire, please tell me wire material ( ocr25al5 or cr20ni80 ),  please also tell me wire diameter you need, because different diameter have different price.
