Process for manufacturing mineral wool, cobalt-based alloys for the process and other uses |
摘要 |
Cobalt based alloys exhibiting high-temperature mechanical strength in an oxidizing medium are provided. The alloys are free of W and Hf and include the following elements in percentage by weight of the alloy: 23 to 34% Cr; 6 to 12% Ni; 6.0 to 10% Ta; 0.3 to 1.2% C; less than 3% Fe; less than 1% Si; less than 0.5% Mn; less than 0.1% Zr; and a balance of cobalt and impurities. Ta/C molar ratios of the alloys are at least 0.3.
