Abstract (en)

[origin: EP2604819A1] Provided is a heat transfer element for manifold that enables the prevention of thermal fatigue of a manifold main body and has good high-temperature strength and oxidation resistance. At least one part of the heat transfer element for manifold 11 is formed from ferritic stainless steel. The ferritic stainless steel contains at least one element, in terms of mass%, of: C: 0.03% or less; Si: 2.0% or less; Mn: 2.0% or less; Cr: 10 to 30%; Nb: 0.8% or less; and Ti: 0.8% or less, and N: 0.03% or less, and the remaining part thereof is formed from Fe and inevitable impurities. Further, an alloy content of the ferritic stainless steel is adjusted so that an A value in equation (1), where A value = Nb + Ti - 4(C + N), is 0.10 or more, and a B value in equation (2), where B value = Cr + 15Si, is 18 or more.
