347H ibyuma bidafite ingese
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.
