Abstract
Abstract
Stainless steel expansion joint, as the connecting part of GIS equipment, has the function of compensating the deformation of GIS caused by cold and hot stress. And it should at least meet the requirements of anti-corrosion and non-magnetic according to the working environment. This work investigate the performance of 304, 316L and 825 austenitic stainless steel expansion joints by metallographic analysis, hardness test, XRD analysis and magnetic analysis, and suggestions on material selection of expansion joint for power grid equipment are put forward.
