Brazing of 422 stainless steel using the AWS classification BNi-2 Braze alloy
Source abstract
Abstract
The study of brazing 422 stainless steel (422SS) using the AWS classification BNi-2 braze alloy as the filler metal is evaluated in the study. The BNi-2 braze alloy demonstrates excellent wettability on the 422SS substrate for temperatures exceeding 1025 °C. The brazed joint is primarily comprised of the Ni-rich matrix and chromium boride. Additionally, the B–Cr–Fe precipitates are formed at the interface between the braze and 422SS. Some Kirkendall porosity is also observed in the braze close to the interface, due to nonsymmetrical interdiffusion between the braze and 422SS substrate. Shear strengths of brazed joints are varied from 306 to 481 MPa. The infrared brazed specimen shows the highest shear strength among all brazed specimens. Increasing brazing temperature and/or time result in decreased shear strength of the brazed joint.
