摘要

Stainless steel, sheet of steel composed of the same, stainless steel joint, and, process to produce a ferric stainless steel sheet, a ferric stainless steel suitable for use as a member for heat exchangers to be hot with metal filling Butt -based filling metal, comprising, on the basis of a percentage of mass, C: 0,03% or less, Si: 3% or less, M: 2% or less, P: 0,05% or less, s: 0,03% or less, Cr: 11 to 30%,NB: from 0,15 to 0,8%,E n: 0,03% or less, where the balance is composed of Fe and incidence impurities, and where a value determined by the following equation is the, 1 or larger: Nb (cx92,9 /12 + nx92,9 /14).
