CORROSION-RESISTANT STEELS

The influence of heat treatment modes (hardening and aging) and uniaxial tension on the structure and magnetic properties of carbonless high-strength corrosion-resistant steel 03Kh20AG11N7M2 containing 0.4% N and having a structure of austenite + 10% -ferrite is studied. The coercive force, the residual induction, and the magnetization of a specimen in a maximum applied field are detected under the action of a load over the whole of the stress – strain curve until the formation of a neck. The magnetization and the coercive force of the steel increase under the action of plastic deformation. The deformation behavior of the magnetic characteristics is discussed with allowance for the special features of the structural state of the material.
