How to identify the content of nickel in stainless steel

How to judge the nickel content in stainless steel?

1. It has been identified by metal instruments.

2. Use stainless steel to test liquid medicine, do experiments with potion and stainless steel to see the chemical reaction, and reflect different colors, which can clearly distinguish the type of stainless steel.

3. Spark discrimination method: mainly used for steel, grinding under the grinding wheel due to friction, high temperature effect, various elements, the number, shape, bifurcation, color, etc. of sparks generated by particle oxidation to distinguish the chemical composition (component elements) And a way to approximate the content. The nickel content is 8.0 percent 11.0 percent. Of course, the nickel content is the same as other elements like carbon, chromium, manganese, sulfur, etc.

4. Magnetic identification: Stainless steel is generally divided into two different classifications: chromium stainless steel and nickel stainless steel. We use ordinary magnetic methods. Actually only one part of stainless steel is magnetic. In fact, two of them are more or less magnetic, but only contain chromium. Stainless steel is more magnetic than nickel-containing stainless steel.

Assuming that only nickel stainless steel has weaker magnetic properties, the nickel will of course be weaker. It is also one of the most economical and common methods. When purchasing stainless steel, many customers are always worried about traps because they cannot identify how much nickel is in stainless steel. , The above gives us some common detection methods to identify how much nickel is contained in stainless steel.

Mainly deal with pure nickel metal products, nickel, nickel mesh, nickel wire mesh, nickel mesh buffer, elastic nickel mesh, titanium wire mesh, pure nickel, nickel alloy mesh, nickel products used in petrochemical, construction, textile, medicine, aviation , aerospace powder metallurgy, heat treatment, glass, clean electric furnace, industrial water, etc.
