Are 304 Stainless Steel Plates and Magnets Attractive?

304 stainless steel has become inseparable in daily life. 304 stainless steel appears in the field of industrial production and has high honors at home and abroad. So what is 304 stainless steel after all? Next, the Stainless Steel Plate 2205 Manufacturer will come to tell you.

People often think that "stainless steel" is "non-rusty steel". If it is rusty, it must be a fake product. This kind of knowledge is of course too simple. The "stainlessness" of stainless steel is not absolutely not rusty, but relatively rustless under certain conditions. If the user uses it improperly, it will naturally rust if it is used in an environment or condition that exceeds its corrosion resistance.

304 Stainless Steel Plate

The stainless steel plate material used in the 304 Stainless Steel Plate product appears to be corroding and rusting. It may also be because the manufacturer's selection of the material is unreasonable, that is, the manufacturer uses an inappropriate stainless steel trademark as the raw material for its product use, or it may be the manufacturer's production and processing skills. But off. In addition, that is, the manufacturers did use fake and inferior stainless steel in the shopping malls that did not meet the relevant national or professional prestige standards as raw materials.

The surface of the stainless steel plate is smooth, has high plasticity, toughness and mechanical strength, and is resistant to corrosion by acids, alkaline gases, solutions and other media. It is an alloy steel that does not rust easily, but it is not absolutely rust-free.

In any case, these should be faced and resolved by manufacturers when acquiring and processing. In response to the fact that inferior stainless steel is still produced and sold in the shopping malls at the time, and shopping mall fraud such as substandard charging and fake quality certificates, how can we master the initiative and quickly detect these frauds when purchasing stainless steel materials, Protected against counterfeit stainless steel? Regarding these perhaps the same bright stainless steels, it is difficult to even distinguish them from true or false according to their appearance. Is there any simple and easy way?

Some people say: This is very simple, use a magnet! What sucks is good, "stainless steel", what sucks is bad, "stainless iron"! At present, this kind of statement and practice seems to be very popular, and even scientific publications and TV programs have implemented this method. Regarding this statement and practice, professional experts have denied it, which is unscientific and extremely wrong. Of the five major types of stainless steels that have been developed and used in the world, only austenitic stainless steel (many 300 series trademarks and 200 series trademarks) is often non-magnetic (after processing or weakly magnetic), while ferritic stainless steel (many 400 series trademarks) ), Duplex stainless steel, martensitic stainless steel, and deposition hardened stainless steel are all magnetic.
