STAINLESS STEEL MATERIAL FOR DIFFUSION BONDING |
摘要 |
Provided is a stainless steel material suitable for diffusion bonded moldings in which diffusion bondability has been further improved without being affected by the extent of surface roughness. The present invention is a stainless steel material for diffusion bonding in which the metal structure before diffusion bonding has a multi-phase structure obtained from two or more of a ferrite phase, a martensite phase and an austenite phase, wherein: the mean crystal grain diameter in the multi-phase structure is not more than 20 µm; γmax represented by formula (a) is 10-90; and creep elongation when a 1.0 MPa load is applied at 1000°C for 0.5 h is at least 0.2%. γmax=420C-11.5Si+7Mn+23Ni-11.5Cr-12Mo+9Cu-49Ti-47Nb-52Al+470N+189 ∙∙∙ Formula (a) The element notations in formula (a) represent the contents (mass%) of the respective elements. |
