Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 19743-2005 "Powder metallurgy water atomized pure iron powder, alloy steel powder". This standard and GB/T 19743- Compared with.2005, the main technical content changes are as follows. --- Product classification has increased free-cutting steel powder (see 3.2); --- Modified some of the brand representation methods (see 3.2, 3.2 of the.2005 edition); --- Increased some grades from 6 to 12 of the original standard (see 3.3, 3.3 of the.2005 edition); --- Revised the chemical composition of some brands (see 4.1, 4.1 of.2005); --- Revised the physical-process performance of some grades (see 4.2, 4.2 of the.2005 edition); ---Modified the batch rule (see 6.2, 6.2 of the.2005 edition); ---Modified the packaging method of the product (see 7.1, 7.1 of.2005 edition); --- Increased transportation regulations for products (see 7.3); --- Increased product storage regulations (see 7.4). This standard was proposed by the China Iron and Steel Association. This standard is under the jurisdiction of the National Standards Committee for Pig Iron and Ferroalloys (SAC/TC318). This standard was drafted. Laiwu Iron and Steel Group Powder Metallurgy Co., Ltd., Angang (Anshan) Metallurgical Powder Co., Ltd., Jiande Yitongjin Is a powder Co., Ltd., Laiwu Xinyi Powder Metallurgy Products Co., Ltd., Metallurgical Industry Information Standards Institute.
