Description
Przedmiotem wynalazku jest ulepszenie stali martenzytycznej odpornej na korozje o podwyz¬ szonej twardosci, wedlug patentu nr 111 153.Stal wedlug patentu nr 111 153 zawiera wago¬ wo: wegla 0.02—0,07%, manganu 0,5—1,0%, krzemu 0,3—0,7%, fosforu do 0,030%, siarki do 0,025%, chromu 13,0—16,0%, niklu 5,0—6,0%, molibdenu 1,0—2,0%, miedzi 1,0—2,0%, tytanu 0,5—1,21% i nio¬ bu do 0,2J%.Stwierdzono wedlug wynalazku, ze wlasnosci uzytkowe stali wedlug patentu nr 111 153, ziwlasz- sza odpornosc na korozje i wlasnosci wytrzymalo¬ sciowe, pozostaja na tym samym poziomie, jezeli zawartosc wegla w stali wzrosnie do 0,12%. Poz¬ wala to na wytwarzanie stali o tym samym prze¬ znaczeniu, bez koniecznosci kosztownego wypala¬ nia wegla w procesie jej produkcji. to 15 Przyklad. Wagowa analiza wytopowa stali: 0,12% wegla, 0,99% manganu, 0,62% krzemu, 0,011% fos¬ foru. 0.012% siarki, 15,3% chromu, 5,2% niklu, 1,02% molibdenu, 1,56% miedzi, 0,08% niobu i 0,79% tytanu. Uzyskane po obróbce cieplnej wlasnosci: HV = 516.RM = 1476 MPa, KM = 5,52 I/cm3, Zastrzezenie patentowe Stal martenzytyczna odporna na korozje o pod¬ wyzszonej twardosci wedlug patentu nr 111153, zawierajaca wagowo: 0,5—1,0% manganu, 0,3— 0,7% krzemu, do 0,030% fosforu, do 0.025% siarki, 13,0—16,0% chromu, 5,0—6,0% niklu, 1,0—2,0% mo¬ libdenu, 1,0—2,0% miedzi, 0,5—1,2% tytanu, do 0,2% niobu, oraz wegiel, znamienna tym, ze zawie¬ ra wagowo 0,07 do 0,12% wegla. 138 260 PL
