<DIV>A537 plate steel is heat-treated. As a result, it displays greater yield
and tensile strength than the more standard A516 grades. <STRONG>A537 steel
plate</STRONG> is ideal for both in boilers and pressure vessels, and is used in
the oil, gas and petrochemical industry.</DIV>
<DIV> </DIV>
<DIV><FONT size=3>Nice to see it provides at least a brief comparison to
A516. I'm sure there are more variables to consider including
cost.</FONT></DIV>

<DIV>A537 was used extensively, as well, especially in the early boats that
Perry built. Maybe you can figure it out. It seems that I recall being told
that it was somewhat harder to weld but had better cold-water-under-pressure
properties. Maybe Dr. Nuytten would weigh in on this, assuming he isn't up to
his ass in DW3000 alligators this week (which I suspect he is).</DIV>

<DIV><FONT size=3>I should have clarified that. It was a cut-and-paste
