| 简介 |
A ferritic stainless steel material is provided that has a chemical composition containing, by mass %, C : 0.001 to less than 0.020%, Si : 0.01 to 1.5%, Mn : 0.01 to 1.5%, P : 0.035% or less, S : 0.01% or less, Cr : 22.5 to 35.0%, Mo : 0.01 to 6.0%, Ni : 0.01 to 6.0%, Cu : 0.01 to 1.0%, N : 0.035% or less, V : 0.01 to 0.35%, B : 0.5 to 1.0%, Al : 0.001 to 6.0%, Sn : 0.02 to 2.50%, rare earth metal : 0 to 0.1%, Nb : 0 to 0.35%, Ti : 0 to 0.35%, and the balance : Fe and impurities, in which a value calculated as {Cr content (mass %)+3×Mo content (mass %)−2.5×B content (mass %)} is from 20 to 45%, and M2B boride-based metallic precipitates are dispersed in and exposed on the surface of a parent phase composed only of a ferritic phase. |
