Wire rod for steel cord

Dia 5.5,6.5mm
Grade WG72LX, WG82LX
Standard GB,JIS,ASTM,DIN,AISI,BS
LF & VD forge;ISO&TUV approve

Under the enterprise inside control standard, the main grade of the hot rolled wire coil for steel cord are WG72LX and WG82LX. Because of the very large deformation in the process of stretching the tire bead wire of common and high strength, it is required to have less contents of S and P, very high requirement to the quantities and varieties of the impurity and accurate rolling tolerance.

Cold Heading Steel

As the main raw material needed by the standard pieces manufacture industries, the cold heading steel, standard executed is GB/T6478—2001 and G3507-1:2005, is used to make work pieces in every specification such as bolt, screw, nut etc. Because of the large deformation in the process of cold heading, the steel grade is required to have less content of sulfur and phosphor, less impurity, excellent machining and mechanical performances and accurate rolling tolerances. could produce the cold heading steel wire coil for cold heading in grade of ML08,ML35 and ML40Cr with diameters range of φ6.5mm~φ20mm.
