The cold rolling with 10% ~60% deformation and tensile tests of 3 mm hot rolled plate of saving in nickel high nitrogen austenitic stainless steel Mn17Cr19N0.6 produced by induction furnace-electroslag remelting are carried out. The microstructure changes in the cold deformation process of high nitrogen austenitic stainless steel are studied by metallographic observation and XRD phase analysis. It is concluded that in the process of cold rolling

with the increase of the deformation

the shape of the grain in the test steel is from lump to flat elongate

and the slip from single slip to cross slip

and the twinning band will eventually be cut and broken. The microstructure of the test steels with different cold rolling deformation is single austenite phase

and there is no other phase. There is no martensitic transformation in the cold deformation process. Therefore

no phase transformation strengthening occurred during cold rolling of test steel

and the deformation strengthening is main in the cold rolling process

the tensile strength of the test steel increases from 1045 MPa by 10% deformation to 1880 MPa by 60% deformation. Therefore

special materials with different strength levels and single austenite structure can be prepared by cold deformation.
