摘要
Abstract
Stainless steel corrugated plates as plate heat exchanger heat transfer components were pro-cessed through cold stamping by oil press.There was residual stress in stamped plates after cold stamping, which induced deformation martensite structure.Sampling from 1 mm thick 321 austenitic stainless steel corrugated plates and carrying out heat treatment tests,the study was found that under 1050 ℃holding 5 min then heat water or air cooling could eliminate residual stress and restore the equiaxial austenite crystal grain organization,finally plate heat treatment process may encountering problems were discussed in the following actual industry.关键词
