Alloy 347H nicyuma gihamye, austenitike, chromium ibyuma birimo columbium ituma ikurwaho ryimvura ya karbide, kandi, kubwibyo, kwangirika kwabantu.Alloy 347 itunganijwe hiyongereyeho chromium na tantalum kandi itanga ibintu byikurikiranya hamwe no guhagarika imitekerereze irenze alloy 304 na 304L ishobora no gukoreshwa muguhishurirwa aho gukangurira no kwangirika hagati yimiterere.Kwiyongera kwa columbium kandi bituma Alloy 347 igira imbaraga zo kurwanya ruswa, ndetse iruta iyindi ya alloy 321. 347H nuburyo bwo hejuru bwa karubone igizwe na Alloy 347 kandi ikerekana ubushyuhe bwo hejuru hamwe nubutumburuke.Ibarurishamibare rya Haosteel ubu ririmo Alloy 347 / 347H (UNS S34700 / S34709) mumpapuro, agapapuro, urupapuro, isahani, uruziga ruzengurutse, ibibari bitunganijwe hamwe nibicuruzwa.

Porogaramu
Alloy 347H ikoreshwa kenshi muguhimba ibikoresho, bigomba gushyirwa muri serivisi mubihe bikomeye byangirika, kandi biranasanzwe mubikorwa byo gutunganya peteroli.
Kurwanya ruswa:
.Tanga kurwanya bisa muri rusange, ruswa muri rusange nka Alloy 304
.Byakoreshejwe mubisabwa aho ibinyobwa nka Alloy 304 bibangamiwe no kwangirika
.Mubisanzwe bikoreshwa mubikoresho bikomeye byo gusudira bidashobora gufatanwa hamwe nibikoresho
ikorwa hagati ya 800 na 150 ° F (427 KUGEZA 816 ° C)
.Alloy 347 ikundwa na Alloy 321 kubidukikije byamazi nubushyuhe buke
.Byibanze bikoreshwa mubushyuhe bwo hejuru aho kurwanya ubukangurambaga ari ngombwa, bikarinda kwangirika kwangirika kurwego rwo hasi
.Birashoboka guhangayikishwa no kwangirika
.Yerekana okiside irwanya izindi 18-8 zose za austenitis
