冷鐓鋼系標準件制造行業所需的主要原材料，產品標準為GB/T6478，用來制作各種規格的螺栓、螺帽、螺釘等工件。此鋼種由于冷鐓加工過程中變形量大，要求鋼中硫、磷等含量低、雜質少，加工性能和機械性能良好，軋制公差尺寸精確。我公司已能生產出滿足冷鐓用途的冷鐓鋼盤條，生產的ML08、ML35、ML40Cr規格為φ5.5mm～φ16mm。As the main raw material needed by the standard pieces manufacture industries, the cold heading steel, standard executed is GB/T6478—2001, 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. Our company already could produce the cold heading steel wire coil for cold heading in grade of ML08,ML35 and ML40Cr with diameters range of φ5.5mm～φ16mm.
