Abstract:

Four brazed stainless steel honeycomb sandwich panels first tested for structural integrity and installed at an exposure site. The condition of the panels was periodically checked by flashtesting. One panel, having silver-manganese brazing alloy failed the flash test after 9 months exposure. Two other silver-manganese brazed panels failed the flash test after 17 months exposure. The remaining panel, having silver-copper-lithium brazing alloy, was returned intact after 38 months exposure. It was subsequently flash-tested, without failure, and then structurally tested in torsional shear to an ultimate failing stress of 77,000 psi. calc.. This test demonstrated the superior corrosionresistance qualities of Ag-Cu-Li brazing alloy for 17-7 PH stainless steel sandwich panels. Author
