SS 309S / SS 309H Silig

SS 309S birta aan birta lahayn waa bir aad u alloyed austenitic ahama bir ah oo loo isticmaalo caabbinta oksaydhka ee heersare ah, heerkul sare, xoog, iyo iska caabin gurguurta. Waxa ku jira nikkel hoose ee birta aan lahayn 309, marka la barbar dhigo birta aan lahayn 310, waxay kordhisaa iska caabbinta hydrogen sulfide (H2S) ee heerkulka sare leh. Waa mid adag oo dhuuban oo si diyaar ah ayaa loo been-abuuri karaa oo loo farsamayn karaa. SS 309S waa nooca kaarboon-hooseeya, waxaana lagu taliyay, in loo isticmaalo halka dareenka iyo daxalka xiga ee uumiga heerkulku sarreeya inta lagu jiro xidhitaanka ay keeni karto caqabad. Steel Steel 309S waxaa loo isticmaalaa iska caabbinta oksaydhka heerkulka sare iyo iska caabinta weerarka H2S. 309S Biraha aan lahayn waa la samayn karaa, shaabadeeyey oo si sahal ah loo sawiri karaa. Annealing in-processor ayaa inta badan loo baahan yahay si loo kordhiyo ductility oo loo yareeyo adkaanta.
