hardening mild steel

Oct 07, 2009 0183 32 I ve tried that mixture,with minimal results Can t recall the formula right nowIf you want to harden mild steel,aquarium charcoal in a sealed crucible will give the best penetration,better than Kasenit It will get file hard,and also will be brittle,so you may want to draw the temper some 10-05-2009, 07 52 PM 4 View Forum Posts...

Rolling metalworking

Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening The starting material is usually large pieces of metal, like semi-finished casting products, such as slabs, blooms, and billets...
