随着我国农机、石油、煤炭、铁道、交通、机械制造等部门科学技术的发展,重大建筑结构和新型的机械设备,愈来愈需要价格低廉且供应方便的低合金高强度钢。近几年来,我国的低合金高强度钢得到了迅速发展,以资源富有的合金元素 Mn、Si 为主的低合金高强度钢生产品种和应用范围在不断扩大,并在冶标(YB)13-63中确定了 Mn、Si、Cu、Ti 为主要组成元素的低合金结构钢12个牌号。16M_n
As China’s agricultural machinery, petroleum, coal, railways, transportation, machinery manufacturing and other departments of science and technology development, major building structures and new types of machinery and equipment, more and more low-cost and convenient supply of low-alloy high-strength steel. In recent years, China’s low-alloy high-strength steel has been rapidly developed, with rich resources of alloying elements Mn, Si-based low-alloy high-strength steel production varieties and applications are expanding, and in the standard (YB) 13 -63 identified in the Mn, Si, Cu, Ti as the main component of low-alloy structural steel 12 grades. 16M_n
