Machining Magnetic
With good work hardening ability, through cold working, the material strength can be significantly improved, and the highest hardness can reach HV500
about. NMS-Y is a steady-state austenite structure, no martensitic transformation occurs during cold rolling, and the magnetic permeability has no obvious change in the whole process.
Meet the requirements of non-magnetic properties of materials for various processing. The cold work hardening curve is shown in the figure:
Application of Non-Magnetic Stainless Steel
What Makes Stainless Steel Non Magnetic?
When high chromium and nickel are added to the steel (the chromium content is about 18%, and the Ni content is more than 4%), the internal structure of the steel presents a structure called austenite, which is non-magnetic and cannot be attracted by magnets.
