Can a magnet be used to determine whether stainless steel is 304? 10781080
It’s better to use the liquid medicine directly. For 201 stainless steel, the droplet turns deep brownish-red instantly; for 202 stainless steel, it turns light brownish-red after about 5 seconds. For 301 stainless steel, the droplet turns light brick red within 1–2 minutes, while for 304 stainless steel, the droplet does not change color within 2–3 minutes. Magnets can be used for elimination. Austenite, no. Ferrite, yes. Martensite works too. If it cannot be attracted by a magnet, it is austenitic, and it is likely to be 304.
It can roughly distinguish between iron and stainless steel, but cannot identify the steel grade.
Other ferromagnetic phases are also present in austenitic stainless steels. . . Magnets and potions are methods used for collecting waste
Pure Ou has no magnetism. During the processing, some Ao turned into Ma. Such as cold working, such as cold bending, and many other situations. In this case, it’s not pure Ohm’s law; it’s normal for it to be able to draw current. Magnets and solutions are used in many situations; for example, on construction sites with steel structures, random inspections are carried out first to make a preliminary assessment, before proceeding with physical and chemical tests. Check it during procurement as well; after all, there are many cases of fake material sheets. Recycling is indeed used the most.
How can we distinguish between 304 and 316L? If we can’t tell the difference, we will treat it as 304
Spectrometers are an effective solution. .
316L cannot be distinguished by handheld spectroscopy.
