Products details

C1018 CHQ steel wire is a medium-low carbon cold heading quality carbon steel wire with relatively high manganese content, balanced strength, toughness and excellent cold formability. It features pure chemical composition and uniform internal structure with strong resistance to cold heading cracking. With phosphate lubrication treatment, it is suitable for high-speed cold heading mass production and can be further heat-treated. It is widely used for manufacturing high-strength screws, bolts, studs, pins and various precision cold-forged mechanical fasteners.

Quality Control

We have advanced inspection equipments so that to carry things out strictly according to the IQC,IPQC and OQC process. Also, our technical staff will record all data of mechanical properties for the finished wire and make quality guarantee certificate to customers. That's our commitment to the quality of our products.

We adopt the high purity nitrogen protection method, which can do the quick heat conduction,even heating and high productivity .After annealing, the hardness and tensile strength are steady,organization spheroidizing rate is high and grain size is uniform and without oxidation and decarburization,the surface of wire is smooth.

We use the phosphoric acid and soap lubricant from Taiwan. In the production line, we use the timer to control the soaking time of each pharmaceutical pool.
