主要研究单位:武汉钢铁公司主要协作单位:鞍钢、铁道部十年规划编号:专17—07309Mn2Cu 钢是以硅—锰为基,结合我国铁矿含铜,而研制的一种低合金高强度钢。在试验室试验的基础上,又在250吨平炉进行工业性试验,轧制成厚度7~14毫米的卷板,供铁道部门作车辆钢板试用。机械性能均达到交货条件的要求。屈服点δs=33.3公斤/毫米~2;
Main research institutes: Wuhan Iron and Steel Company The main collaborative units: Anshan Iron and Steel, Ministry of Railways ten years Planning number: Special 17-07309Mn2Cu Steel is based on silicon - manganese, combined with China’s iron ore containing copper, and developed a low alloy high strength steel . On the basis of laboratory tests, industrial tests were again carried out in a 250-ton open hearth furnace and rolled into coils of 7-14 mm in thickness for trial use by the railway authorities for steel plates. Mechanical properties meet the delivery requirements. Yield point δs = 33.3 kg / mm ~ 2;
