Stainless Steel Induction Heating -1

Today, we going to talk about Stainless Steel Induction Heating. First of all, stainless steel is a metal alloy with a mixture of some elements. There is an iron content of not less than 50%, chromium ratio of 5% to 30%, nickel, and molybdenum about 8.5% and a maximum carbon content of 2%.Stainless Steel Induction Heating -2

It has resistance to rust and corrosion due to the formation of a coherent and invisible thin layer of chromium oxide. This invisible thin layer helps it to adhere to the surface of the metal and prevent corrosion.

Moreover, this layer is sufficiently protective whenever the proportion of chromium in steel is high.

How To Know Stainless Steel is of High Quality?

This name (stainless steel) originally comes from the fact that stainless steel doesn’t rust as easily as the ordinary carbon steel rusts. However, it is, in fact, corrosive and rusty under special conditions.

Its resistance to rust varies by the amount of chromium. So, it is important to choose the correct type of stainless steel according to the application in which it will be used.

Cases for Stainless Steel Induction Heating:Stainless Steel Induction Heating

  • You can carry out induction heating for Austenitic steel with a low power density in the case of using an air-cooled Litz wire inductor. However, you can use much higher power density in the case of using a water-cooled inductor. Although physic has its tricks good or bad.
  • In the case of the thickness of the metal sheet is between 0.1 up to 0.5 mm, it is as good as a ferritic steel. Also, this means that a great part of the magnetic field will flow through the sheet.
  • Bad one 1/3:

according to the process of manufacturing, ferrite can appear in the welded part. In other words, this means that this area will be heated much more than the non-welded area.

  • Bad one 2/3:

When the metal is cold worked martensite is created causing an expanse of the magnetic permeability and an increase of the heating in the stressed area.

  • Bad one 3/3:

Combining welding and cold working, spots with 2 to 4 times the nominal power density can appear causing overheating.

  • Do not wait for the help of the thermal conductivity of the metal to smooth this difference. Austenitic stainless steel has a very poor thermal conductivity. This is why the handles of the pans are made with i
