Abstract (en)
[origin: EP1357199A1] A precipitation-hardened soft magnetic ferritic stainless steel comprises C: not more than 0.2 mass%, Si: 0.01-3.0 mass%, Mn: not more than 0.5 mass%, S: not more than 0.3 mass%, Cr: 12.0-19.0 mass%, Ni: 1.0-4.0 mass% and Al: 0.2-4.0 mass% and further contains at least one of Ti: less than 0.5 mass% and Zr: less than 0.3 mass% and the remainder being inevitable impurities and Fe, and has substantially a microstructure of a ferrite phase after a solution treatment and an aging treatment.
