镍铬是在合金钢中使用得最广泛和最多的合金元素,无论是在结构钢中或是在不锈耐热钢中,它们的含量都相当高。目前,镍铬在我国尚不是富产金属,从国家的经济和国防利益着想,寻找镍铬钢的代用品种是当前极迫切的任务。工业的迅速发展使镍的消耗量日益增加,因而造成目前世界上普遍的镍的供应困难。各主要产钢国家都采取了一些紧急措施,减少镍在合金钢中的使用。事实上,自从1936年以来节约用镍一直受人重视,不
Nickel-chromium is the most widely used and most widely used alloying element in alloy steels, both in structural steel and in heat-resistant stainless steels, and their contents are quite high. At present, Ni-Cr is not yet a rich metal in our country. Considering the national economic and national defense interests, it is an extremely urgent task to search for alternative Ni-Cr steel products. The rapid development of industry has led to the increasing consumption of nickel, which has caused the current supply of nickel, which is widespread in the world. Some major steel-making countries have taken some urgent measures to reduce the use of nickel in alloy steel. In fact, nickel has been valued by people since 1936, no
