                  USX CORPORATION REPORTS HIGHER SECOND QUARTER
                        RESULTS FOR ITS U. S. STEEL GROUP
       PITTSBURGH, July 18, 1995 -- USX Corporation reported second quarter 1995
net income for its U. S. Steel Group (NYSE:X) of $81 million, or 99 cents per 
share, on sales of $1.6 billion.  The results represent a substantial 
improvement over second quarter 1994 net income of $56 million, or 65 cents per 
share, on sales of $1.5 billion.
        The Steel Group's second quarter 1995 results included a $35 million
unfavorable estimated aftertax effect of charges related to the Pickering v. USX
litigation which arose out of the sale of USX's Geneva (Utah) Works in 1987 and
costs associated with repair work on the Gary Works' No. 8 blast furnace.  The
furnace, which is expected to be back on line in mid-August, was extensively
damaged by an explosion on April 5.  Second quarter 1994 results included no
significant special items.
        Operating income in the second quarter of 1995 from Steel and Related
Businesses, excluding $56 million in pretax charges related to the Pickering v.
USX litigation and the blast furnace repair work, totaled $160 million, or $58
per ton, on steel shipments of 2.8 million tons, compared with $64 million, or
$24 per ton, on steel shipments of 2.6 million tons in the second quarter of
1994.  Additional pretax charges of approximately $10 million to complete the
repairs to the blast furnace are expected to negatively impact third quarter
1995 operating income.

        USX Board Chairman Thomas J. Usher noted that despite the blast furnace
outage, the Steel Group produced more than 3 million tons of raw steel in the
second quarter, compared with 2.9 million tons in the second quarter of 1994.
He added that U. S. Steel's improved results over second quarter 1994 also
reflected higher transaction prices from a year ago and an improved market for
tubular goods.
        The USX chairman noted, however, that, a combination of the seasonally
slow third quarter, the growing domestic supply base, inventory build-ups by
many customers, and a sustained high level of steel imports will continue to
apply competitive pressure on flat-rolled steel sales. Nevertheless,
comparatively high levels of domestic steel consumption, along with strong
export demand, are expected to keep U. S. Steel's facilities running at high
utilization rates for the balance of the year.
        "Despite continued strong demand, we believe competitive success will
require ongoing attention to cost-reduction, quality and service," Usher said.
"The U. S. Steel Group is committed to continuing its impressive progress in
each of those areas as demonstrated by 33 METALPRODUCING magazine's 1995 TOP
(Top Operations & Plants) Award which was recently awarded to the Mon Valley
Works." This award recognizes facilities which have distinguished themselves as
low-cost international competitors with world-class processes, product quality
and customer service.
