This standard replaces GB/T 9971-2004 "raw iron." This standard compared with GB/T 9971-2004, the main technical changes are as follows. --- Remove the initial billet varieties and related requirements, the original standard of flat bar and flat steel bar; --- New product brand YT4. Adjust YT1, YT2, YT3 chemical composition of manganese, sulfur, copper and the upper limit of control element YT1 aluminum Control cap, an increase of various grades of oxygen, titanium content requirements; --- Increase product smelting method requirements; --- Canceled the original standard appendix A and Appendix B, carbon and sulfur detection methods directly referenced to the relevant national standards; --- Refined the surface quality requirements. This standard is proposed by China Iron and Steel Association. This standard by the National Standardization Technical Committee Steel (SAC/TC183) centralized. The main drafting units of this standard. Shanxi Taigang Stainless Steel Co., Ltd., Anshan Iron and Steel Co., Ltd., Metallurgical Industry Information Standards Institute. The main drafters of this standard. Chen Zemin, Li Huifeng, Zhang Jiansheng, Liao Xiangwei, Yan Chengming, Zhang Yanrui, Liu Aikun, Li Yanru, Miao Xiao. This standard replaces the standards previously issued as. --- GB/T 9971-1988, GB/T 9971-2004. Raw iron1 ScopeThis standard specifies the symbols and varieties of raw materials, classification, size, shape and weight, technical requirements, test methods, inspection rules, packages Equipment, signs and quality certificates. This standard applies to electric alloys, precision alloys (including soft magnetic materials, hard magnetic materials, flexible alloys, expanded alloys, etc.), low carbon stainless steel, Ultra-low carbon stainless steel and powder metallurgy and other raw materials for the use of pure iron billets, hot-rolled steel rods and hot-rolled rod.2 Normative referencesThe following documents for the application of this document is essential.
