[TheForge] Rust-resistance: Iron Pillar of Delhi

Andy,

It (high phos) would forge like sh_t.  First off it is cast iron, not
wrought we are talking about here -- or most likely that what it is -- can't
tell from the article. Many of the cast irons from the UK and Europe had the
"problem" of high phos.  That was one of the problems with early mild steel
made from local pig iron in the Bessemer process.  Bessemer himself brough
in pig iron from Sweden that was very low in phos and was able to make good
mild steel. (1860's).  Later the Basic Bessemer process was develop that
removed phos in the slag.  The early Bessemer furnaces had an acid lining.
Today the BOF (Basic Oxygen Furnace) is very similar to the Basic Bessemer
process but uses Oxygen rather than air in the conversion of pig iron to
steel.

As to Pure Iron, have you tried some 1006 or 1008?  Not as low carbon as
Pure Iron but very very low.  To try some get  some very large nails or
spikes. (But not ring shank which are high carbon and very hard.)  You can
purchase round stock in these alloys in sizes up to about 1 1/2 inches I
think.  1006 has .006 carbon or just 6 points.
