High-Performance Wire Rods Produced with DLP

DLP (Direct in-Line Patenting) wire rods multiplied equal to or more than 20 years from the entry into production and the dosage expanded steady by them. The product basic concept of the DLP wire rods is the energy saving wire rods which can omit the lead patenting processing which is implemented by the customer. Also, one reason why DLP wire rods are increasingly used is that the heat-treatment is in line with efforts to protect our global environment because lead is not applied. This paper introduces the basic characteristics of the DLP wire rods and high-strengthened DLP wire rods which were commercialized recently in the market.
