由上海钢研所负责,北京钢铁研究总院,上海锅炉厂,上海核工程研究设计院等单位参加研制的秦山卅万千瓦核压力容器主焊缝焊接材料和内壁不锈钢堆焊材料于1992年10月31日在上海通过冶金局组织的专家鉴定。 秦山核电站是我国自行设计、制造的第一座卅万千瓦核发电设备(即七二八工程)、1973年我所承接了“七二八”工程压力容器用钢及配套焊接材料的任务,经过五年多的攻关,取得了大量试验数据,完成了Ho6Mn_2NiMoA主焊缝焊接材料, By the Shanghai Steel Institute is responsible for the Beijing Iron and Steel Research Institute, Shanghai Boiler Works, Shanghai Nuclear Engineering Research and Design Institute and other units to participate in the development of Qinshanqian million kilowatts core pressure vessel welding materials and welding of the inner wall of stainless steel cladding materials in 1992 10 On January 31, the expert appraisal organized by the Metallurgical Bureau in Shanghai was conducted. Qinshan Nuclear Power Station is the first QWV nuclear power generation equipment designed and manufactured by our country (ie 728). In 1973, I undertook the task of “Seventy-eight” project of pressure vessel steel and matching welding materials, More than five years of research, has made a lot of test data, completed Ho6Mn_2NiMoA main weld welding materials,
