“917”钢是根据我国自然资源特点自力更生研制成功的一种高锰不导磁金属材料。从六十年代起,“917”钢已普遍采取热轧手段,生产板材及棒材、扁钢、角钢、球扁钢等各种型材,积累了不少经验,七二年天津会议上制订了《917型钢临时供应技术条件》。“917”钢锻造生产乃是从七十年代开始。我厂自七一年至七二年两年中,作为国内第二个单位多次承担了“917”钢的试 “917” steel is a kind of high-manganese non-magnetic metal material successfully developed according to the characteristics of natural resources of our country. Since the 1960s, “917” steel has generally adopted the hot rolling method to produce various profiles such as plate and bar, flat steel, angle steel and flat steel, and has accumulated a lot of experience. At the Tianjin Conference in 1972, it formulated “917 steel temporary supply of technical conditions.” “917” steel forging production but from the seventies. I plant from 1981 to 1972 two years, as the second unit in China has repeatedly assumed the “917” steel trial
