苏联苏联是富产镍铬的国家,所以苏联使用的合金结构钢迄今仍然有很多是基于这两个元素的。在卫国战争期中,产镍的矿区曾一度被德军占领,因而引起镍的供应紧张。当时苏联的冶金学者们曾从事研究不含镍的合金结构钢,山于资料关系,不在此介绍。最近苏联的冶金学者们研究了含硼的合金结构钢,准备用来代替含镍的钢种(表4)。据说这些新钢种不久即将公布为苏联国家标准规格。
The Soviet Union is a country rich in nickel and chromium. So far, so many structural steel alloys used in the Soviet Union are based on these two elements. During the Patriotic war, nickel-producing mines were once occupied by the Germans, causing a tight supply of nickel. At that time, the Soviet Union’s metallurgists had engaged in the study of nickel-free alloy structural steel. Recently, Soviet metallurgists studied boron-containing alloy structural steels and were prepared to replace nickel-containing steels (Table 4). It is said that these new types of steel soon to be published as the Soviet Union national standard specifications.
