发明名称 HIGH PURITY Fe-Cr ALLOY HAVING EXCELLENT FORMING WORKABILITY
摘要 PROBLEM TO BE SOLVED: To provide an Fe-Cr alloy which has excellent forming workability by clearing up the relation between the contents of impurities and the form of nonmetallic inclusions in a high purity Fe-Cr alloy. SOLUTION: In the Fe-Cr alloy containing 8 to 90 mass% Cr, the total content of C, N, O, S and P is controlled to <=0.020 mass%, and the ratio of the total content of MnO and SiO2 in oxide inclusions is controlled to >=60 mass%. By increasing the total content of MnO and SiO2 in the inclusions, they become soft ones finely dispersed in the production, and cause no cracking on forming.
