304 stainless steel steel are magnetic, in the popularity of 304 stainless steel why is there magnetic?
By what resolution is the magnetism of stainless steel?
Stainless steel is in the eyes of many people do not contain magnetic, magnetic is stainless iron, was so know it is not correct, because the raw material of stainless steel for many category is magnetic in 304 as an example, the 304 magnetic is one of the many people think that is not authentic stainless steel more varieties, 304 stainless steel is more useful because it is over, so why 304 magnetic? This question from the physical structure, doubts 304 originally is not with magnetic meantime such as stainless steel plate, but why some products made in stainless steel belt?
The reason is very simple deformation caused by the internal structure change, 304 some from austenite to ferrite, the greater the change in deformation, so some products of stainless steel through the manufacture of the smaller the greater the magnetic, then is there a way to deal with the magnetic?
Also has that is the demagnetization processing, in the drawing after the demagnetization processing, after the magnetic can hit to drop but to reach the complete non-magnetic is impossible. Just how big drop, so that every customer to buy a stainless steel top feeling with magnet suck feel not stainless steel is a fault, now there are two ways for judging whether stainless steel, the stainless steel liquid, this relatively simple, usually 304 potions point become red above is authentic, the other is spectrum check can know composition, went up from components, stainless steel chemical composition of stainless steel stainless steel corrosion resistance decreases with the increase of carbon content, and therefore, most of stainless steel and carbon content are low, the biggest is not more than 1.2%, Some steel even has a Wc (carbon content) of less than 0.03% (e.g. 00Cr12). The main alloying element in stainless steel is Cr (Chromium). Only when Cr content reaches a certain value, steel has corrosion resistance. Therefore, the stainless steel general Cr (chromium) content is at least 10.5%. Stainless steel also contains Ni, Ti, Mn, N, Nb, Mo, Si, Cu and other elements. The corrosion resistance of stainless steel decreases with the increase of carbon content, therefore, the carbon content of most stainless steel is low, the maximum is not more than 1.2%, some steel Wc (carbon content) even less than 0.03% (such as 00Cr12). The main alloying element in stainless steel is Cr (Chromium). Only when Cr content reaches a certain value, steel has corrosion resistance. Therefore, the stainless steel general Cr (chromium) content is at least 10.5%. Stainless steel also contains Ni, Ti, Mn, N, Nb, Mo, Si, Cu and other elements.
So there's no way to tell whether steel is magnetic or not; some products are going to be slightly magnetic when they're made. Look well!
