Washington Steel Corporation was a highly successful post-war stainless steel production company, located in Washington, Pennsylvania. Washington Steel was the first U.S. company to use a Sendzimir Mill, invented by Polish inventor Tadeusz Sendzimir to cold-roll stainless steel. Washington Steel was founded in 1945〔"50 Years of Innovation: The Story of Washington Steel Corporation" (1995) Washington, PA: Washington Steel Corporation〕 by T. S. Fitch who was a member of the U.S. War Production Board from 1942 to 1944. As a member of the Board's Steel Division, he saw a Sendzimir Cold Rolling Mill in operation and began to appreciate its potential value for rolling stainless steel into thin, high-accuracy sheets.〔Fitch, T. S. (1967). Washington Steel was Born South of Columbus (Newcomen Society of North America, New York).〕 Washington Steel began production in 1947, with a 39-inch Z-mill much wider than any previously produced (it cost $278,000, installed). The light-gauge stainless steel had exceptional dimensional accuracy and surface quality, and in its first year of operation the company posted net income of $237,000. Sales in 1948 were $4.6 million, and by 1954 more than quadrupled to $19 million. The company's ability to achieve dimensional precision in strong, light-gauge steel quickly won favor in the aerospace industry, and was used in the Atlas missile which served as the launch vehicle for NASA's Project Mercury, which sent the first American into earth orbit in 1962 (John Glenn). The company was listed on the New York Stock Exchange under the symbol WSS on Feb 7, 1968, and remained there until its purchase by Blount, Inc in 1979. Washington Steel was purchased by Lukens Steel Company in April 1992 for $274 million. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Washington Steel Corporation」の詳細全文を読む スポンサード リンク
