Abstract: Un punzón de perforación y laminación tiene una película compuesta de óxidos, tales como Fe3O4 y FeO, y de Fe (metal), la cual está formada sobre la superficie del metal base por medio de proyección por arco eléctrico usando un alambre cuyo componente principal es Fe y, debido a esta película, se puede materializar un punzón excelente en cuanto a efectos de apantallamiento térmico y prevención de enclavamiento y asimismo prolongar la vida útil del punzón. Más aun, en la regeneración de este punzón, se puede formar nuevamente una película a través de las etapas de chorreo por granallas del punzón usado en perforación y laminación, y proyección por arco eléctrico, en este orden; en consecuencia resulta posible regenerar el punzón a bajo costo y en un tiempo corto.

Abstract: Fe-Cr alloy billet manufacturing method according to the present invention, since the blooming is carried out with the high reduction rate surface of the cast steel covered with a scale layer of a large area rate as 70 % or more and without the descaling applied, can reduce the indentation and inclusion of the scale. Thereby, in the case of a billet for use in seamless steel pipes being manufactured from a steel strip of a Fe-Cr alloy, surface treatment before tube-making can be largely reduced. Thereby, when the Fe-Cr alloy billet is adopted in manufacturing seamless steel pipes, since even the Fe-C r alloy steel pipe relatively hard to process can be manufactured at low manufacturing cost and efficiently, it can be widely applied in a field of manufacturing hot seamless steel pipes.

Abstract: A MARTENSITIC STAINLESS STEEL PRODUCT HAVING A CHROMIUM CONTENT OF 9 TO 15% BY WEIGHT AND A SURFACE FROM WHICH MILL SCALES GENERATED DURING PRODUCTION ARE REMOVED BY A SHOT BLASTING. THE SURFACE SATISFIES THAT, WHEN A COLOR IMAGE OF THE SURFACE TAKEN WITH 640 X 480 PIXELS IS ANALYZED ON BLUE COLOR AND A HISTOGRAM OF THE PIXEL NUMBERS AND THE TONES DIVIDED INTO 0 TO 255 CLASSES IS OBTAINED, A RELATIONSHIP BETWEEN THE MAXIMUM FREQUENCY Y P AND THE TONE VALUE XP AT WHICH YP IS COUNTED SATISFIES AN INEQUALITY, 800XP- YP-27000 > O. THIS STEEL PRODUCT IS SUPERIOR IN WEATHERABILITY UNDER ATMOSPHERIC ENVIRONMENTS, AND ALSO SUPERIOR IN SULFIDE STRESS CRACKING RESISTANCE UNDER ENVIRONMENTS CONTAINING HYDRO-SULFIDE.

Abstract: A martensitic stainless steel product having a chromium content of 9 to 15 % by weight and a surface from which mill scales generated during production are removed by a shot blasting. The surface satisfies that, when a color image of the surface taken with 640 x 480 pixels is analyzed on blue color and a histogram of the pixel numbers and the tones divided into 0 to 255 classes is obtained, a relationship between the maximum frequency Yp and the tone value Xp at which Yp is counted satisfies an inequality, 800Xp - Yp - 27000 > 0. This steel product is superior in weatherability under atmospheric environments, and also superior in sulfide stress cracking resistance under environments containing hydra-sulfide.
