A Comparison Study on Depth of Decarburization and the Role of Stable Carbide Forming Elements in 1075 Plain Carbon Steel and 440A Stainless Steel

A Comparison Study on Depth of Decarburization and the Role of Stable Carbide Forming Elements in 1075 Plain Carbon Steel and 440A Stainless Steel by Rebecca Cioffi, M.S. Graduate at Rensselaer Polytechnic Institute.

 

This thesis reflects much of the work done in the 2011-2012 FIERF project entitled “Effect of Carbide Formers on Steel Decarburization”.  Due to the large cost associated with specially prepared laboratory ingots, it was elected to perform a comparative study of 1075 plain carbon steel and type 440A stainless steel.  The compositions of these commercial steels are similar, except, of course, for the large difference in chromium content (13.05% vs. 0.19%).  It is believed that the contrast in decarburization response makes an important point.
