WHY DO SOME STAINLESS STEEL BOTTLES HAVE MAGNETISM?

One of our customers told us they want to put a magnetic ring on the cap of stainless steel bottle, but we told them stainless steel is with no magnetism.


The fact is our customer told us they already tried it on the stainless steel bottles, and they found stainless steel bottles do have magnetism. Why did this happen ?


Stainless steel pipe when proceeded with water swelling, stretched and vacuumized under high temperature, the body of stainless steel will have some change. Part of bottles will have magnetism as it makes stainless steel change from austenite into martensite. Martensite stainless steel has a few magnetism.


That is the reason why some stainless steel bottles have the magnetism. One thing calls your attention, not every stainless steel bottle may have magnetism, and not each part of the stainless steel bottle may have magnetism. For example, the bottom of the bottle have little magnetism, as the stretching degree is small, nearly no change when processing.


Let’s make it clear, some stainless steel bottles may have magnetism, but not every bottle. The magnetic force depends on the stretching degree when processing.
