The role of Haoxing Steel Nickel in SUS201 stainless steel coils Nickel is the main alloying element of the formation of strontium, but the role of nickel can only be fully demonstrated when it is combined with chromium. If pure nickel is used, a pure austenite single-phase structure is required in low-carbon nickel steel, and the nickel content needs to be more than 24%. In fact, when the nickel content needs to reach 27%, the corrosion resistance of 201 stainless steel can be remarkably improved. Therefore, in the stainless steel "target=_blank> stainless steel material composition, there is no nickel as the alloying element. When nickel and chromium are combined, nickel can improve the corrosion resistance of steel, such as the iron body stainless steel" target =_blank>A small amount of nickel is added to the stainless steel to transform the metallographic structure from a single-phase iron body structure to an austenitic ten-ferrite two-phase structure, so that the stainless steel "target=_blank> stainless steel coil can be improved by heat treatment. Strength. Further increase in nickel content can be changed to single-phase austenite. If 8% nickel is added to steel with 18% chromium content, complete austenite structure can be obtained. This is type 18-8. Chromium-nickel austenitic 200 series stainless steel "target=_blank> stainless steel is widely used in Lishan, because stainless steel "target=_blank> stainless steel plate has high corrosion resistance and good deformation and weldability, and Nickel can expand the passivation range and improve corrosion resistance, especially in non-oxidizing media (such as dilute sulfuric acid). Nickel has a tendency to form carbides that is weaker than iron, can promote graphitization, and can be weakly increased. Hardenability of large steel. In medium carbon and high carbon steel, when the content reaches the effective content value, it tends to retain austenite after quenching. In addition, nickel is added to chromium 201 stainless steel "target=_blank> stainless steel coil It can improve the corrosion resistance of chrome 201 stainless steel "target=_blank> stainless steel in sulfuric acid, acetic acid, oxalic acid and neutral salt (especially sulfate).
