冶金、化工、机械、国防等部门都需要大量的耐热钢,但是,一般说来,耐热钢都含有较高的铬镍元素,而铬镍元素在我国还是比较稀缺的,需从国外进口。不少厂矿由于缺少耐热钢材,不得不采用普通碳素钢来代替,由于普通碳素钢的抗氧化能力极差,需要经常更换,因而浪费了大量的钢材,又造成备品、备件紧张,严重地影响了生产。因此,提高各种构件的抗氧化能力,是一个需要解决的问题。
Metallurgy, chemical industry, machinery, defense and other departments require a lot of heat-resistant steel, but, in general, heat-resistant steels contain higher chromium and nickel elements, and chromium-nickel elements in China is still relatively scarce, need to import from abroad . Due to the lack of heat-resistant steel, many factories and mines had to replace ordinary carbon steel. Since ordinary carbon steel has poor anti-oxidation ability and needs to be replaced frequently, a large amount of steel was wasted and the spare parts and spare parts are tense and serious Affected the production. Therefore, to improve the antioxidant capacity of various components is a problem to be solved.
