How To Identify The Content Of Nickel In Stainless Steel?

May. 09, 2019

How to identify the nickel content in stainless steel, as a Nickel 201 Wire Mesh China Wholesaler, let's talk about four ways to identify the nickel content:

1. Use stainless steel test solution to identify. Stainless steel test solution is also called stainless steel syrup. As long as it drops a little on stainless steel, the syrup immediately reacts with stainless steel. The different colors of the reaction can clearly determine the type of stainless steel.

2. Identification by metal instrumentation.

3. Spark identification method: It is mainly used for steel. In the grinding of grinding wheel, the chemical composition (composition of materials) is identified due to the difference in the number, shape, bifurcation and color of sparks generated by various elements and particles due to friction and high temperature. Element) and a method of approximate content. The content of nickel is also 8.0% to 11.0%. Although the nickel content is also important, other elements such as carbon, chromium, manganese and sulfur are also important, and more attention should be paid!

4. Stainless steel is generally divided into chrome stainless steel and nickel stainless steel (only one of a variety of classifications). The method of magnetic overhauling stainless steel that we usually use is only applied to a section of stainless steel. In fact, both are more or less magnetic. However, chromium-containing stainless steel is more magnetic than nickel-containing stainless steel. To put it bluntly, you can use magnets to attract chromium-containing stainless steel. The nickel-containing stainless steel attracts very weakly. If it is only for nickel-containing stainless steel, of course, the weaker the magnetic, the more nickel is contained. The method is also the simplest and most commonly used method.
