Take Heart! Slow Corrosion in Salt Water

["Robert Hlavacek" <bob.hlavacek@xxxx>]

***** Moderator's Note *****
As a previous post indicated, there is a lot of information regarding
the body dies in the archives. At the time of that discussion, it was 
observed that a salvage recovery of the dies was really not economically
feasible due to the damage sustained by the dies over two decades
under water, the lack of demand for newly-manufactured parts,
and the oversupply of current new and used part inventories.
Unless someone actually brings one of the dies up from the 
deep, please consider this discussion closed.

"Brine and sea water corrode steel at a slow rate, and the metal can be used
where iron contamination is not objectionable."

This is a direct quote from: "Perry's Chemical Engineers' Handbook" Fourth
Edition. It is known as the Chemical Engineering "bible".

Other facts - 1. Corrosion/rust decreases with decreasing temperature. 2.
Also from Perry's: General corrosion in sea water, (static or slow moving)
for iron and steel is rated 4 on a 0-6 scale. 4 is good, 6 is "normally
excellent", 0 is Unsuitable. The rating refers to the materials corrosion
performance in sea water.
