347 / 347H Icyuma

Alloy 347 ni ibyuma biringaniye, austenitike, chromium ibyuma birimo columbium hitawe ku iherezo ry’imvura ya karbide, bityo ikangirika hagati y’imiterere. Alloy 347 iringanizwa no kwiyongera kwa chromium na tantalum kandi itanga imitungo ihanitse kandi ihangayikishije kuruta alloy 304 na 304L, ishobora no gukoreshwa muguhishurirwa aho gukangurira no kwangirika hagati yimiterere. Kwagura columbium nabyo byemerera Alloy 347 kugira imbaraga zidasanzwe zo kurwanya ruswa, iruta iy'umuti wa aliyumu 321. Alloy 347H nuburyo bwo hejuru bwa karubone igizwe na Alloy 347 kandi ikerekana ubushyuhe bwo hejuru hamwe nubutumburuke.
Ibiranga

• Imyitwarire yo hejuru cyane hamwe no guturika iyo ugereranije na 304
• Nibyiza kuri serivisi yubushyuhe bwo hejuru
• Yatsinze ubukangurambaga hamwe nimpungenge za ruswa
• Irashobora gukoreshwa mubushyuhe bwo hejuru
• Bitewe no gutuza ibintu bitanga uburyo bwiza bwo kurwanya ruswa mugihe ugereranije na 304 / 304L

• Gutunganya imiti
• Ibikoresho byo gutunganya ibiryo no kubika
• Ibikomoka kuri peteroli Gutunganya ibice bya catalitike yamenetse, serivisi ya aside polythionic
• Umusaruro wa farumasi
• Imyanda yubushyuhe bwo kugarura imyanda

Alloy 347 isahani idafite ibyuma byerekana neza ruswa irwanya ruswa isa na 304. Yakozwe kugirango ikoreshwe mu kigero cy’imvura ya chromium karbide kuri 800 - 1500 ° F (427 - 816 ° C) aho ibishishwa bitaringaniye nka 304 bikorerwa mu ndimi zitandukanye. igitero. Muri ubu bushyuhe, muri rusange kurwanya ruswa ya Alloy 347 isahani idafite icyuma iruta icyuma cya Alloy 321. Alloy 347 wongeyeho ikora bimwe bisumba Alloy 321 mugihe cya okiside ikomeye kugeza kuri 1500 ° F (816 ° C). Umuti urashobora gukoreshwa nkigice cyibisubizo bya nitric; acide nyinshi ya acide kama yubushyuhe buringaniye no muri acide fosifori nziza mubushyuhe buke hamwe nibisubizo bigera kuri 10% mubushyuhe bwinshi. Alloy 347 isahani idafite ibyuma irwanya polythionic aside ihangayikishije ruswa muri serivisi ya hydrocarubone. Irashobora kandi gukoreshwa muri chloride cyangwa fluoride yubusa caustic ibisubizo kubushyuhe buke. Alloy 347 isahani idafite ibyuma ntigikora neza mubisubizo bya chloride, ndetse no mubitero bito, cyangwa muri acide sulfurike.
