Read MoreCopper sulfate point test is a simple way to quickly distinguish ordinary carbon steel and all types of stainless steel wire rope. The concentration of copper sulfate solution used is 5%-10%. Before the point test, the experimental area should be thoroughly removed from the oil or other impurities, and a small area should be polished by grinding machine or soft grinding cloth, and then the test liquid drops to the grinding place. Ordinary carbon steel or iron in a few seconds will form a layer of outer metal copper, and the surface of stainless steel does not produce copper precipitation or display copper color.

Read MoreAnnealing is to restore the plasticity of wire, improve the tensile strength of wire, hardness, elastic limit, etc., the wire after annealing is called annealing wire. In the production process of annealing wire, it is very important to ensure the quality of the finished wire, make the wire have certain strength and suitable degree of soft and hard. The annealing temperature is between 800 ℃ and 850℃, and the length of furnace tube is lengthened appropriately for enough holding time.
