How to distinguish stainless steel ?

Stainless steel products are widely used in our daily life ,Like stainless steel pot , tray and so on . It plays an important role in our life .  So how do we distinguish stainless steel ?

There is a saying that stainless steel can attract magnets . It is not totally true . The magnet doesn’t grab only if the steel is an austenitic type .Then let let’s look at the composition and discrimination method.

Stainless steel uses metallic element in its mixture to thwart the affects of corrosion. General steel, or steel, is usually virtually fully iron and is employed for a lot bigger applications than “stainless steel”. stainless-steel is employed largely in room appliances, utensils, etc…

The best thing we can come up with is to find a way to measure the chromium content of the steel you are looking at. If it’s around 3% chromium, it’s probably standard steel. If it’s somewhere between 10-15% chromium it’s probably stainless steel (or even 4% plus).

There is one check we have seen for home testing “surgical steel” that could be a higher grade stainless-steel, that’sto place scotch tape on one section of fabric then soak it in water for a twenty four hour amount, then let it air dry for twenty-four hours. You take away the tape and gently polish the exposed spaces to ascertain if there was any discoloration or erosion on the exposed area. This check is especially for surgical steel jewellery, but stainless-steel is meant to resist rusting over commonplace steel, thus it would work for different steel varieties as well .
