Haynes 230 (UNS N06230) – Aloyi ya Nickel-Chromium-Tungsten-Molybdenum ikoreshwa mu bushyuhe bwinshi cyane

Ingufu zidasanzwe z'ubushyuhe bwinshi n'ubushyuhe buhamye– Haynes 230 ni ibikoresho bikomeye kandi bihuzwa n’ubushyuhe bwinshi n’uburyo bworoshye bwo gukora mu bushyuhe bw’icyumba. Iyi alloy igira akamaro cyane mu gukoreshwa igihe kirekire cyane ku bushyuhe bwa 1200°F (650°C) cyangwa irenga. Uruvange rwihariye rwa tungsten (13-15%) na molybdenum (1-3%) mu gukomeza umuti ukomeye, hamwe na karubone igenzurwa (0.05-0.15%) na chromium (20-24%) mu gukomeza karubine, bitanga imbaraga zidasanzwe mu bushyuhe bwinshi. Iyi alloy igaragaza ko idashobora gushonga mu gihe kirekire ku bushyuhe bwinshi, igakomeza imiterere yayo mu gihe kirekire.

Ubudahangarwa bwo hejuru bwo kurwanya ogisijeni– Haynes 230 itanga ubushobozi bwo kurwanya cyane ibidukikije bitera ogisijeni kugeza kuri 2100°F (1149°C) mu gihe kirekire. Ingano ya chromium nyinshi (20-24%) ikora igipimo cy’uburinzi bwa ogisijeni cya Cr₂O₃ gikomeye kandi gifata. Kongeramo lanthanum (0.005-0.05%) byongera uburyo bwo gufatana kwa ogisijeni, bikarinda kwangirika mu gihe cy’ubushyuhe. Ibi bitanga imikorere myiza mu bihe by’ubushyuhe aho izindi alloys zananirwa no kwangirika kwa ogisijeni.

Ubudahangarwa bw'ibanze ku bidukikije bitera nitriding– Iyi aluminiyumu irwanya cyane ibidukikije bitera nitride, bigatuma ikoreshwa mu gutera inkunga icyuma gishyushya amoniya n'ibindi bikorwa aho nitride yangiza vuba aloyi nto.

Ubushyuhe burambye kandi buhamye cyane– Bitandukanye n’ibindi bikoresho byinshi bishyuha cyane bibora binyuze mu gice cya sigma cyangwa ibindi bintu bigabanya ubushyuhe, Haynes 230 igumana ubushobozi bwayo bwo gukora no gukomera kwayo binyuze mu gihe cyo kuyikoresha mu gihe kirekire. Ibi bituma ubuzima bwayo bwizewe bupimwa mu myaka aho kuba mu mezi.

Kwaguka kw'ubushyuhe buri hasi– Iyi aloyi igaragaza imiterere yo kwaguka k’ubushyuhe buri hasi ugereranyije n’izindi aloyi nyinshi zikoresha ubushyuhe bwinshi, bigabanya umuvuduko w’ubushyuhe n’umunaniro mu bice bikoreshwa mu gushyuha. Ibi bigira akamaro cyane cyane mu bice bya turbine ya gaze mu kirere no mu ikoreshwa ry’ibikoresho byo mu nganda.

Ubuhanga bwiza bwo gukora no gusudira– Haynes 230 ifite imiterere myiza yo gukora no gusudira. Ishobora kuba icuzwe cyangwa ishyushye, mu gihe ifatiwe kuri 2150°F (1177°C) igihe gihagije. Ifumbire kandi ikorwa byoroshye no gukora ikonje bitewe n'ubushobozi bwayo bworoshye bwo kugenda. Ishobora gusudira hakoreshejwe uburyo butandukanye, harimo arc ya gaz tungsten (GTAW), arc ya gaz metal (GMAW), gusudira irwanya, na arc ya gaz arc (SMAW).

ASME Igenzura ry'amabwiriza y'ubwato– Haynes 230 irebwa n'urubanza rwa ASME Vessel Code No. 2063 rw'Igice cya I n'Igice cya VIII, rwemerera gukoreshwa mu miyoboro y'umuvuduko hakurikijwe ASME Boiler and Pressure Vessel Code.

Igihe kirekire cyo gukora– Iyi aluminiyumu irashobora kumara igihe kirekire kurusha ibyuma bitagira umugese na nikeli ku kigero cya 100 kugeza kuri 1 bitewe n'ubushyuhe. Ubundi buryo, imbaraga nyinshi za aluminiyumu 230 zemerera gukoresha ubunini bw'igice cy'igishushanyo kugeza kuri 75% byoroheje ugereranyije n'ibice bito nta gihombo mu bushobozi bwo gutwara imizigo.
