[TheForge] Cheese is cold-short!

German tanks broke in WWII because of the sulfur content in the steel exposed to sub-freezing temperatures in Russia

Even with chip breakers these steels with sulfur and also lead really improve high speed machining.  For many products this is very big cost saving.  These steels don't forge well, nor do they weld (arc) well either.  Locally we can get free drops from a company making items for Snap On but it not worth working with even if it is free.  Most of these steels I have seen are sold as bar stock for use in high speed machine centers or screw machine lathes.

Ya learn something every day.  Basically they're introducing a defect in the steel so the chips break off more easily!? Seems to me there'd be better ways.  I thought that was what chip breakers (on lathe tools) were for.
