Carbon Steels

US $200.00



Carbon Steels are those with relatively more carbon than electrical steels. They are grouped into low carbon steels (usually 0.05% to 0.3% C) and industrial steels (with more than 0.3%C).  This folder also contains magnetic properties of both mild steels and industrial steels.  It includes a variety of  10xx series steels, 4340, HSLA, tool steels etc in cold/hot rolled, annealed/ un-annealed conditions. It also lists six grades of pure iron (ie. carbon removed as much as possible, so has higher permeability and does not suffer from aging). 

These steels are very lossy above ~ 5 Hz. So they are used mostly in applications that carry large flux at low flux densities and frequencies. These include rotors, pole pieces, solenoids, actuators, lifting magnets etc.   They are more ductile and machinable than electrical steels. Because of higher carbon content, they are prone to aging.  Their magnetic properties can vary with manufacturer, heat, form and annealing. They are available as sheets, rods, tubes etc in fully annealed or hardened condition.

MagWeb’s Carbon Steel Folder has 182 excel files listing magnetic properties of these materials.  Of these, 179 files contain B(H) magnetization curves/permeability curves while 3 files contain core loss curves.  For a full list of commercial names of all these materials, please click on List of Materials – G.  Carbon Steels. 

Version 5 also includes a DIGEST file that lists all these materials and their discrete magnetic properties in a single excel file.

By downloading this folder you will have 182 files on magnetic properties of low carbon steels produced worldwide at your finger tips!

Please review the Handbook for more technical information on these materials. The version 5 contains several less-known facts on magnetic properties of these steels; they will help you to better utilize these materials for magnetic purpose.
