Not All Iron Is Magnetic (Magnetic Elements)
As with iron, the magnetic properties of these elements depends on their crystal structure and whether the metal is below its Curie point. α-iron, cobalt, and nickel are ferromagnetic, while γ-iron, manganese, and chromium are antiferromagnetic.

Is stainless steel magnetic? Does it depend on the amount ...
However, the most common stainless steels are 'austenitic' - these have a higher chromium content and nickel is also added. It is the nickel which modifies the physical structure of the steel and makes it non-magnetic. So the answer is yes, the magnetic properties of stainless steel are very dependent on the elements added into the alloy, and ...

Both of these variations are magnetic. Increasing the chromium content to around 18% and adding nickel at about 10% to the alloy changes the microstructure to austenitic and makes the metal non-magnetic. This is the most commonly used stainless steel. The chromium increases the alloy's corrosion resistance, while the nickel improves the grade ...

Abstract. Pure chromium has been prepared from chromium amalgam and its magnetic susceptibility has been studied over the temperature range 90 to 620° K. The mass susceptibility is practically constant over this range, the slight departures from constancy being partially explainable by the effects of thermal expansion on the experimental results.
