SS 309S / SS 309H Waya

SS 309S igwe anaghị agba nchara bụ a ukwuu alloyed austenitic igwe anaghị agba nchara tinye n'ọrụ n'ihi na ya pụtara ìhè ọxịdashọn nguzogide, elu-okpomọkụ, ike, na creep iguzogide. Ọdịnaya nickel dị ala nke igwe anaghị agba nchara 309, ma e jiri ya tụnyere igwe anaghị agba nchara 310, na-abawanye nguzogide ya na mwakpo hydrogen sulfide (H2S) na oke okpomọkụ. Ọ siri ike na ductile na enwere ike ịpụta ya ngwa ngwa ma rụọ ya. SS 309S bụ ụdị carbon dị ala, ma akwadoro ya, na-eji ebe nghọta na corrosion na-esote site na oke okpomọkụ condensates n'oge mmechi nwere ike bụrụ ihe ịma aka. A na-eji igwe anaghị agba nchara 309S mee ihe maka nguzogide ọxịdashọn dị elu yana iguzogide ọgụ H2S. Enwere ike ịmepụta igwe anaghị agba nchara 309S, stampụ ma dọpụta ya ngwa ngwa. N'ime usoro annealing na-adịkarị mkpa iji mụbaa ductility ma belata isi ike.
