Stainless steel processing, because of the oxidation resistance of 304, the most common oxygen cutting can't move, so we have to ion cutting, and ion welding is also needed when welding, which gives people the first impression that it is difficult to process; In plastic processing, because people appreciate the luster of its metal surface and cannot destroy it, this requirement adds a lot of trouble to the processing operation and gives people a second feeling that it is difficult to process; When cutting gold, compared with ordinary carbon steel, under the same hardness, the ductility of stainless steel is much greater, which is what people call "adhesion". At the same time, the density of stainless steel is higher than that of carbon steel, and it consumes a lot of electricity and heat, resulting in high temperature and easy to burn "knives".

Stainless steel: The corrosion resistance of stainless steel decreases with the increase of carbon content. Therefore, the carbon content of most stainless steels is relatively low, with the maximum not exceeding 1.2%, and the Wc (carbon content) of some steels is even lower than 0.03% (for example, 00Cr 12). The main alloying element in stainless steel is Cr (chromium), and only when the Cr content reaches a certain value can the steel have corrosion resistance. Therefore, the Cr content of stainless steel is at least 10.5%. Stainless steel also contains elements such as nickel, titanium, manganese, nitrogen, niobium, molybdenum, silicon and copper.
