<div><font style="background-color: transparent;">One other thing comes to mind on this. Phil uses A516Gr70 in the DW2000s. It occurs to me that if there was a demonstrable benefit to A537, he would have used taken advantage of it. And he didn't, apparently. Interesting. Don't know why, though. Maybe it has something to do with welding stainless inserts in and the heat treatment thereof. Just a guess.</font></div>

<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><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>
