塑料模具钢是工业发展所需求的一个专用系列钢种。近年来在GB1299标准中只反映了我国引进生产的3Cr2Mo钢,该钢种有较好的境面加工性能,但解决不了塑料原料所固有的化学腐蚀的问题,所以长期进口瑞典的S-136(H)钢。据此,广州市科委以《1993-Z-59》的科研项目,要求广州市冶金工业研究所开发研制一种具有良好抛光性能、硬度渗透性强、抗腐蚀性能良好的新型塑料模具钢35Cr13MoNiV(PDS-3522)的钢种。此钢种经广东省标准计量情报研究所检索,均无国内外资料,后被列入“省级重点新产品试验鉴定计划项目”。
Plastic mold steel is a specialized series of steel required for industrial development. In recent years, GB1299 standard only reflects the introduction of China’s production of 3Cr2Mo steel, the steel has better processing performance, but can not solve the inherent chemical corrosion of plastic raw materials, so long-term imports of Swedish S-136 ( H) Steel. Accordingly, Guangzhou Science and Technology Commission to “1993-Z-59” research projects require the Guangzhou Institute of Metallurgical Industry to develop a good polishing performance, hardness permeability, good corrosion resistance of the new plastic mold steel 35Cr13MoNiV (PDS-3522) steel grades. The steel by the Guangdong Provincial Institute of Standards and Information Retrieval, no domestic and foreign information, was included in the “provincial key new product testing program.”
