Magnet Test For Stainless Steel

I was looking into getting a portable induction burner.

Magnet test for stainless steel.

There are three. Nice article to go through. There are two process methods to make it bright both are surface treatments. So out of curiosity i did a kitchen magnet test on my tri ply stainless steel cuisinart multiclad pro cookware.

The magnet stuck well on my le creuset enameled cast iron cookware but not the mcps. The stainless steel magnet test is a popular and easy way for consumers to supposedly test the grade of stainless steel used in a grill. If the sample remains attached or resists being pulled off it s a ferrous metal such as steel iron nickel or cobalt. The magnet did not stick.

Be aware that magnets can stick to some non metal surface such as ferrite ceramics. Magnetic particle testing mt also known as magnetic particle inspection mpi is a non destructive test ndt method used to detect surface or subsurface near to surface discontinuities this ndt method can be used on metals which can be easily magnetized ferromagnetic. Ferritic stainless steels such as grades 409 430 and 439. To test magnetic 430 stainless steel against galvanized steel get a a galvanized steel comparison scratch both and place in vinegar 5 percent acetic acid and see what happens after one hour four hours one day etc.

The magnet test is not a correct way to verify stainless steel stainless steel is a common name for metal alloys that consist of 10 5 or more chromium cr and more than 50 iron fe. If the magnets attaches to the grill then it is not made of high grade stainless steel. Asme ansi b36 10 19 carbon alloy and stainless steel pipes dimensions pipe sizes inside and outside diameters wall thickness schedules moment of inertia. Don t assume that if it doesn t stick.

The following types of stainless steel are typically magnetic. Magnetic and non magnetic stainless steels can typically be grouped together based on the type of stainless steel. Although it is called stainless a better term for it is highly stain resistant it is a darker metal. Other qualitative tests are listed in atlas technote 1.

Which types of stainless steel are magnetic. The magnetic response of a piece of steel is a quick and qualitative test that can be useful for sorting grades of stainless steel. Metals can be classified as ferromagnetic paramagnetic or diamagnetic. If the magnet does not attach to the grill it is made of high grade stainless steel.
