At present, there are more than 100 known chemical elements, and about more than 20 kinds of chemical elements can be encountered in the steel materials used in industry. For the practice of people in the long struggle with the corrosion phenomenon and the formation of the stainless steel special steel series, the most common elements of a dozen, in addition to the basic elements of the iron steel, microstructure and properties of stainless steel is the greatest impact elements: carbon, chromium, nickel, manganese, silicon, molybdenum, titanium niobium, titanium, manganese, cobalt, copper, nitrogen, etc.. 

In addition to carbon, silicon, and nitrogen, these elements are elements of the transition family in the periodic table of chemical elements.  E-BON the most excellent stainless steel company, which provide you with Stainless Steel Bar Tools Set china.
  
In fact, the industrial application of the stainless steel are exist at the same time and several dozen elements, when several elements coexist in a single entity in the stainless steel, their impact is much more complicated than when they are alone, because in this case should not only consider the elements of its function, but also pay attention to their influence each other therefore, the organization decided to stainless steel sum of effects of various elements.

1). Influence and effect of various elements on the properties and microstructure of stainless steel

The determinant role of 1-1. chromium in stainless steel is that there is only one element to determine the element of the stainless steel, which is chromium, each of which contains a certain amount of chromium. So far, there are no chromium - free stainless steel. Chromium is the main element determining the properties of stainless steel. The fundamental reason is that chromium is added into the steel as an alloy element, which promotes the internal contradiction movement to the development of corrosion resistance. This change can be explained from the following aspects:

The electrode potential of chromium iron-based solid solution to improve the chromium iron absorption of iron passivated electronic. E-BON the stainless steel specialist, coffee grinder manufacturer china.

Passivation is the phenomenon that the corrosion resistance of metals and alloys is raised because of the inhibition of the anode reaction. There are many theories about the passivation of metal and alloy, including the theory of film, the theory of adsorption and the theory of electron arrangement.
