一、新合金钢系统的概况解放以来,我国的合金钢生产在党的正确领导下,得到了迅速发展,由于学习苏联的先进经验,采用了苏联的合金钢钢种,掌握了冶炼加工技术,大大扩大了品种。1952年前重工业部正式颁布了七项有关合金钢的部颁标准,包括159个钢种,奠定了合金钢品种标准化的基础,克服了钢种的不合理现象,统一了技术规格,这对扩大合金钢品种和提高质量起了积极作用,并促进了产量的迅速增长。到1957年全国共生产372个钢种,钢材的自给率已达86%。1952年的部颁标准是参照苏联国定标准制订的,
Since the liberation of the new alloy steel system, China’s alloy steel production under the correct leadership of the party has been rapid development, due to the advanced Soviet experience, the use of the Soviet Union alloy steel, mastered the smelting processing technology, Greatly expanded the variety. Before 1952, the Ministry of Heavy Industry formally promulgated seven ministerial standards on alloy steel, including 159 steel grades, laying the foundation for the standardization of alloy steel varieties, overcoming the unreasonable phenomenon of steel grades and unifying the technical specifications, Alloy steel varieties and improve the quality played a positive role, and to promote the rapid growth of output. By 1957, a total of 372 steel products were produced across the country, and the self-sufficiency rate of steel reached 86%. The ministerial standards of 1952 were formulated with reference to the Soviet Union’s national standard,
