Because chromium stainless steel under any state can be attracted to a magnet, chromium nickel stainless steel in annealing state is generally no magnetic, after cold working, some will have magnetic stainless steel barbecue net. But the high manganese content in the high manganese steel is non-magnetic; Chromium nickel nitrogen stainless steel magnetic is more messy? Some nonmagnetic, some magnetic, some longitudinal surface non-magnetic stainless steel barbecue net and horizontal surface magnetic. Therefore, a magnet can chromium stainless steel barbecue net and chromium nickel stainless steel base differences, but can't correct difference some special properties of steel grade, even can't divide the specific steel grade.
