Stainless Steels (aka Chromium Steels) are those that add 12 to 30% Chromium. Those with higher Chromium have superior corrosion resistance, but their magnetic properties are not that great. The 400 series are magnetic. They are available as plates, slabs, and rounds, etc, some of which are machinable. Their core loss is high, so they are used mostly in DC or low-frequency applications where high corrosion resistance is required. Their permeability is low, ranging 500 to 2000. Applications include rotor shafts and solenoids.
Version 7 stores both B(H) and Core Loss properties of each grade in a single excel file. MagWeb’s Stainless Steel Folder has 52-grade files. It lists the magnetic properties of a variety of stainless steels. For a full list of all these grades, please click ‘Steels Selector’ on the home page.
Version 7 uses its proprietary SMOOTHER that smooths the data. Most measured data is ‘rough’ (i.e. it has kinks in slopes that will slow the speed at which a software converges to a solution). To prevent such slowdown, MagWeb locates all rough spots in the raw measured data and spot-cleans them.
Version 7 also uses its proprietary EXTRAPOLATOR that extrapolates the smoothed data to saturation. So you have access to data that can be used to simulate your product in deep saturation. You also have access to the saturation flux density Js.
By downloading this folder, you will have 52 excel files of magnetic properties of all magnetic stainless steels produced worldwide!
Please review the ‘Steels Handbook’ for more technical information on the magnetic properties of these materials. It will also help you identify optimal stainless steels that offer the best magnetic properties.
