Stainless steel steamer steel, magnetic and nonmagnetic. Many people are misled into thinking that it is easier to rust with magnetism than without magnetism. This understanding is too general. In fact, the presence or absence of magnetism does not represent the quality of rust prevention, but mainly depends on the material of steel.
Non-magnetic materials are mainly 20 1 and 304, and magnetic materials are mainly 430 and YH2 1CT. The magnetism of 430 is slightly stronger than that of nonmagnetic 20 1 stainless steel, followed by YH2 1CT. 304 stainless steel is an American standard non-magnetic stainless steel, which is austenitic and used for medium and high-grade ships.
Extended data:
Pot bottom: Most non-magnetic steamers have an additional bottom called double bottom. The double bottom has a magnetic conductive sheet. The non-magnetic pot itself can not be directly used on the induction cooker, but can be used with double bottoms, which can prevent the pot from deforming.
A good pot has a three-layer composite bottom and two layers of magnetic conductive sheets. Some pots only have a simple layer of magnetic steel, which looks quite big, but the magnetic conductive effect is not good, and it affects the life of the induction cooker.
Pot cover: There are three kinds of pot covers: steel cover, glass cover and combined cover. Generally, low-grade magnetic steamer is a glass cover, low-grade steamer is mostly a glass cover, and middle-grade steamer is mostly a combination cover. The cost of the combined cover is also relatively high.
Handle: all-inclusive and plug-in, all-inclusive will not cause danger. Bakelite materials, recycled plastic materials, plastic materials, all-steel, most of the steamers are made of bakelite, which has high mechanical strength, good insulation, heat resistance and corrosion resistance.
