How to evaluate the nickel content in stainless steel?

1. According to the identification of metal materials and equipment.

2. Use stainless steel to detect liquid drugs, take medicine and stainless steel to do experiments to see the chemical reaction, reflect different colors, and can clearly identify the type of stainless steel.

3. Flame identification method: identify steel, grinding under the grinding wheel due to friction, high temperature effect, various elements, the number, shape, bifurcation, color, etc. And this method of similar composition. Nickel composition is 8.0 percent 11.0 percent. Of course, the composition of nickel is the same as carbon, chromium, manganese, sulfur and other elements.

4. Magnetic identification: Stainless steel is usually divided into 2 different types: chromium stainless steel and nickel stainless steel. When you use the general magnetic method, only one position of stainless steel is magnetic, in fact, the two are more or less full. It is magnetic, but chromium-containing stainless steel is stronger than nickel-containing stainless steel.

Assuming that the magnetism of only nickel stainless steel is weak, the nickel will of course be weaker. It is also a kind of method that is often used in economical and economical ways. When many consumers buy stainless steel, it is difficult to distinguish that stainless steel contains many nickels. , Many people are always worried about the trap, and the above will give you a little common detection method to identify stainless steel including many nickels.

Mainly dealing with pure nickel metal products, nickel, nickel mesh, nickel mesh, nickel mesh buffer, elastic nickel mesh, titanium mesh, pure nickel, nickel alloy mesh, nickel products for petrochemical equipment, construction engineering, textile industry , medicine, international airlines, aerospace powder metallurgy, heat treatment methods, wired glass, cleaning electrolysis furnace, modern tap water, etc.
