UNS S34700 (Icyiciro cya 347)

347 ibyuma bitagira umuyonga, bizwi kandi nka UNS S34700 na Grade 347, nicyuma cya austenitike kitagira ibyuma gikozwe muri .08% karubone ntarengwa, 17% kugeza kuri 19% chromium, 2% manganese ntarengwa, 9% kugeza 13% nikel, 1% silikoni ntarengwa , ibimenyetso bya fosifore na sulfure, 1% byibuze kugeza 10% ntarengwa ya columbium na tantalum hamwe nuburinganire bwicyuma. Icyiciro cya 347 ni cyiza kuri serivisi yubushyuhe bwo hejuru kubera imiterere yubukanishi; Ifite kandi imbaraga zo kurwanya ruswa hagati yimiterere nyuma yubushyuhe bwubushyuhe bwimvura ya chromium karbide iri hagati ya 800 ° na 1500 ° F. Irasa nicyiciro cya 321 kubijyanye no kwangirika kwimiterere hagati yabyo bigerwaho hifashishijwe columbium nkibintu bihamye kugirango Koresha iyi ngingo. Icyiciro cya 347 ntigishobora gukomera binyuze mu kuvura ubushyuhe, ariko imitungo ihanitse irashobora kuboneka binyuze mukugabanya ubukonje.
