本方研究了稀土元素对Cr-Mn-N铜性能的影响。试验得出,加入0.1％稀土元素能提高钢的抗氧化性,对钢的机械性能影响不大。试验钢种己成功地用于,1000℃下工作的炉用耐热构件。
The party studied the rare earth elements on the Cr-Mn-N copper properties. Test results show that adding 0.1% rare earth elements can improve the oxidation resistance of steel, the mechanical properties of steel has little effect. The test steels have been successfully used for furnace heat-resistant components operating at 1000 ° C.
