                          World's first
Continuous Seamless Tube Mill
                 -National Tube Company
       develops revolutionary new mill design
2,000 feet of seamless pipe a minute! That's
what the world's first continuous seamless pipe
mill will turn out upon completion.
  Developed by National Tube Company -
U.S. Steel Subsidiary - at its Lorain, Ohio
Works, the mill has already been referred to as
"one of the greatest advances in the steel in-
dustry during the past 50 years."
  The new continuous process it features will
eliminate several steps in the conventional
method of making seamless pipe and will be
comparable to that of continuous strip and sheet
mills. Designed to produce sizes ranging from
2 inches to 4'/2 inches OD, the mill not only will
provide quality products at lower cost, but
greater service to the consumer.
  This revolutionary seamless mill design is an-
other demonstration of National Tube Com-
pany's position of leadership in providing indus-
try witn Dotn quality and quantity products.          Construction view showing

The spirit behind this latest National Tube Company development typifies
the spirit behind projects being conducted in all United States Steel Corpora-
tion Subsidiaries. It is a pioneering spirit-one that requires qualified
men in
all branches of engineering. See your Placement Officer for a copy of "Paths
of Opportunity in U.S. Steel" if you would like to take part in these
fascinating
-and important developments.
