Properties And Organization Of Stainless Steel

There are more than 100 known chemical elements, and about 20 kinds of chemical elements can be encountered in steel materials commonly used in industry. 

For the special steel series of stainless steel formed by people's long-term struggle against corrosion, there are more than a dozen of the most commonly used elements. In addition to iron, the basic element of steel, the one that has the greatest impact on the performance and structure of stainless steel The elements are: carbon, chromium, nickel, manganese, silicon, molybdenum, titanium, niobium, manganese, nitrogen, copper, cobalt, etc. Except for carbon, silicon and nitrogen, these elements are all elements in the transition group in the periodic table of chemical elements. 

In fact, stainless steels used in industry all have several or even a dozen elements at the same time. When several elements coexist in a unity of stainless steel, their effects are much more complicated than when they exist alone, because in this In this case, it is necessary to consider not only the role of each element itself, but also the influence between them, so the structure of stainless steel is determined by the sum of the influence of various elements.
