Plain Carbon Steels Classification and Limitations

As it is difficult to harden carbon steel-parts thicker than 1.5 cm up to centre (due to low hardenability),higher uniform strength by hardening and tempering cannot be obtained in thicker parts.Even in thinner sections,in heat treated conditions,carbon is increased to get a maximum strength of 700 N/mm2,above which,a rapid decrease in Plain Carbon Steels Classification and Limitations As it is difficult to harden carbon steel-parts thicker than 1.5 cm up to centre (due to low hardenability),higher uniform strength by hardening and tempering cannot be obtained in thicker parts.Even in thinner sections,in heat treated conditions,carbon is increased to get a maximum strength of 700 N/mm2,above which,a rapid decrease in Oxide dispersion-strengthened steel PM2000 after dynamic Since nanostructured materials produced by deformation are in general less thermally stable than their less-refined counterparts ,the annealing behaviour of DPD-processed PM2000 is also investigated in the present work.Both transmission electron microscopy (TEM) and electron backscatter diffraction (EBSD) are used here to enable a detailed
