Household stainless steel pot and spoon that can be attracted by magnets. Is it made of iron? What iron is it?

Chrome stainless steel.

The main elements of stainless steel are iron, chromium and nickel. Stainless steel is usually divided into chromium stainless steel and chromium-nickel stainless steel. Stainless iron is just a commonly used oral name, but there are differences in composition. There is no nickel in what we call stainless steel iron, that is, chromium stainless steel. Originally, the nickel-containing part of stainless steel was replaced by iron, which can be adsorbed when tested by a magnet, but the nickel-containing nickel-chromium stainless steel cannot be adsorbed by a magnet.

Most of the low-grade cookware in daily life is nickel-free, so-called stainless iron. Because of the high price of nickel, the cost of stainless steel containing nickel will go up a lot. Quality is the first consideration for high-grade cookers. Nickel-containing stainless steel is corrosion-resistant, rust-free, compact in structure, high in finish and soft in color. We should pay more attention when buying, take a magnet with us and try it when necessary to avoid being fooled. However, experienced people can also tell the two from their appearances.

The following are the components of several stainless steels, all of which are of high quality:

304 0Cr 18Ni9 mainly contains about 18 chromium, about 9 nickel and the rest iron.

3160cr 17ni 12mo2 mainly contains about17 chromium, about12 nickel, about 2 molybdenum and the rest iron.

31600cr 17ni 14mo2 is mainly composed of chromium17, nickel14, molybdenum 2, and the rest is iron.

3 16 stainless steel is a good grade austenitic stainless steel. It is not true that it will be magnetic after processing.
