目前我国机床工地所用的合金结构钢主要是以镍铬钢为主。这与我国目前资源情况不相适应，在大跃进的形势下，这个问题若不解决，将会影响机械工业的发展。为此，冶金部根据我国国情，创造了以硅、锰、钒、钛合金元素为基础的新钢种，并大量供应这些钢材。为便于大家熟悉与掌握新钢种的基本性能、机械性能及其热处理工艺，大力推广与试用新合金钢种，特发表此文，供工作时参考。
At present, China’s machine tool used in the structural steel is mainly based on nickel-chromium steel. This is incompatible with the current situation of our country’s resources. Under the situation of the Great Leap Forward, if this problem is not solved, it will affect the development of the machinery industry. To this end, the Ministry of Metallurgy has created new steel grades based on elements of silicon, manganese, vanadium and titanium alloys according to China’s national conditions and supplied these steel products in large quantities. In order to facilitate everyone familiar with and master the basic properties of the new steel, mechanical properties and heat treatment process, to promote and trial use of new alloy steel, special published article, for reference when working.
