Armco...
the totally involved steel maker
Marine steels. It takes more than
furnaces and a rolling mill to pro-
duce them.
It takes total involvement... an
open dialogue with naval architects
and designers, with ship owners
and operators, with engineers in
the yards and men who weld.
You have to be familiar with a
unique breed of specs. ABS, HY-
80, MIL-S-16113C Grade HT . . . to
name some. We know them well.
All of them. We specialize in ma-
rine steels.
Including new high-strength
steels for saving weight, adding
strength, improving stability, in-
creasing performance in today's
modern vessels. Steels like the
100,000psi minimumyield strength
Armco SSS®100 series (ASTM A 514
and A 517). And Armco High-
Strength B (ASTM A 441), with
minimum yield strengths up to
50,000 psi, 70,000 psi minimum
tensile strength.
Plus a complete family of heat-
treated carbon steels providing ex-
ceptional notch toughness. New
Armco VNT™ Steel. Armco LTM.
Armco QTC® Steel. And Armco Lo-
Temp™ and Super-Lo-Temp™
Steels (ASTM A 537).
Total involvement means more
than just products, too.
It means we welcome the idea of
working with you in search of the
best steels for your needs. It means
a full array of technical data de-
signed to assist you in using those
steels. It means the metallurgical
knowledge of our skilled team is
yours whenever it's needed. It
means prompt service from people
who care. Armco people. Let's get

Armco Marine Steels
The giant, oceangoing tug-barge is a new concept in which a high-powered tug and barge
are joined in a notch at the stern of the barge to form a rigid unit that can be operated in any
sea condition. Barges have the capacity of a standard cargo vessel and can be built to carry
liquid, pressurized, refrigerated, or bulk cargo. The Ingram Corporation of New Orleans
and Nashville, who developed this versatile concept along with Breit Engineering Inc., has
ordered the first combined tug-barge unit. Alabama Dry Dock and Shipbuilding Company
in Mobile, Alabama, is building the 279,000-barrel tanker barge and Southern Shipbuildin
Corporation, Slidell, Louisiana, is working on the accompanying 11,000-hp tug, most
powerful ever built in the United Stales. In addition to several grades of ABS steels in both
units, Armco Lo-Temp Steel went into the critical bow of the tug and stern portion of the
barge where the two units join. Armco Lo-Temp is a 50,000 psi minimum yield strength
heat-treated steel noted for excellent notch toughness and weldability. Overall length of
the combined unit-622 ft. Beam-87 ft. Depth-46 ft. 4 in. Speed-14 knots, laden. Crew-
14 men.
