METHOD FOR MANUFACTURING STAINLESS STEEL PRODUCT BY NITROGEN ABSORPTION TREATMENT AND STAINLESS STEEL PRODUCT PRODUCED BY THE METHOD |
摘要 |
<p>A method for manufacturing a stainless steel product, which comprises contacting a bulk product of a ferritic stainless steel having been formed into a desired shape through melting with an inert gas containing nitrogen at 800 DEG C or higher, to thereby convert the structure of the whole or a part of the bulk product to austenite and produce an austenitic product or a product having a two-phase structure comprised of ferrite and austenite, respectively. The method allows the reduction of the manufacturing cost of a formed austenitic stainless steel product to a satisfactorily low level, which results in the manufacture of a stainless steel product having satisfactory characteristics in both of strength and corrosion resistance at a satisfactorily low cost. <IMAGE></p> |
