SS 309S / SS 309H Umugozi

SS 309S ibyuma bitagira umuyonga nicyuma cya austenitike kitavanze cyane cyakoreshejwe muburyo budasanzwe bwo kurwanya okiside, ubushyuhe bwinshi, imbaraga, hamwe no guhangana n’ibikurura. Nikel yo hepfo ya Steelless Steel 309, ugereranije na Steel Steel 310, yongera imbaraga zo kurwanya igitero cya hydrogen sulfide (H2S) mubushyuhe bwinshi. Birakomeye kandi bihindagurika kandi birashobora guhimbwa byoroshye kandi bigakorwa. SS 309S ni verisiyo ntoya ya karubone, kandi irasabwa, gukoresha aho gukangurira no kwangirika nyuma yubushyuhe bwo hejuru mugihe cyo guhagarika bishobora gutera ikibazo. Ibyuma bitagira umuyonga 309S bikoreshwa mukurwanya ubushyuhe bwo hejuru bwa okiside no kurwanya igitero cya H2S. 309S Ibyuma bitagira umuyonga birashobora kuzunguruka, gushyirwaho kashe no gushushanya byoroshye. Muburyo bwa annealing mubisanzwe birakenewe kugirango wongere guhindagurika no kugabanya ubukana.
