Increasing nickel in stainless steel head One of the main reasons is the formation of austenite crystal structure, thereby improving attributes such as plasticity, weldability and toughness stainless steel, nickel austenite. Ordinary carbon crystal structure called the ferrite Movement of the body-centered cubic (BCC) structure, adding nickel, stainless steel head procure the crystal structure from a body-centered cubic (BCC) structure into a face-centered cubic (FCC) structure, such The structure is referred to austenite. However, nickel is not the only element of this nature. Common austenite-forming elements are: nickel, carbon, nitrogen, manganese, copper. Significance for prediction stainless steel having a crystal structure of these elements in the relative importance of the formation of austenite.
