Izinto zokwakha

Inzuzo enkulu yamabhawodi e-Hastelloy B3 uma kuqhathaniswa nama-alloys e-B-2 amandla awo okugcina i-ductility enhle kakhulu ngesikhathi sokuchayeka kwesikhashana emazingeni okushisa aphakathi nendawo.

I-Inconel 600 fasteners yenziwe nge-Inconel. Amabanga ahlukene e-Inconel anezingoma ezihlukene. I-ASTM B166 Inconel 600 Stud Bolts yenziwe nge-alloy ene-72% Nickel, 14% Chromium, kanye ne-Iron engu-6%, equkethe ne-Carbon, i-Silicon, iManganese, isulfure, ne-Copper.

Ngaphezu kokumelana nokugqwala okuhle namandla aqine kakhulu, ama-Duplex 2205 Hex Bolts nawo anokuqina okuphezulu kwendawo. Lokhu kanye nongqimba lwe-oxide ye-passive olwakhiwe ngokungezwa kwe-chromium yisizathu esenza ukuthi izibophelelo zensimbi engagqwali ezingama-2205 zisetshenziswe embonini yasolwandle.

Izibophelelo zensimbi engagqwali eziyi-Duplex zenziwe ngama-alloys anokuqukethwe kwe-chromium ephezulu nokuqukethwe kwe-nickel okuphansi ukuya kokumaphakathi.

Esinye isizathu sezakhiwo ezinhle zemishini ye-duplex stainless steel fasteners singabalelwa ekuhlanganiseni kodwa okunokulinganisela kwe-austenitic microstructure kanye ne-ferritic microstructure ekhona ku-alloy.

I-Mixed Austenitic Ferritic Microstructure ¨C Insimbi ithola igama layo ngenxa yokuthi i-microstructure ye-2205 duplex stainless steel fastener alloy iyi-duplex noma i-duplex alloy. Lokhu okubili kwe-austenitic ferrite kuholela ekushintsheni kwe-alloy.

Ayaziwa nangokuthi insimbi engagqwali eyi-duplex ejwayelekile, lawa mabhawodi angama-2205 angamanye amabanga ensimbi engagqwali asetshenziswa kakhulu.

Le ingxubevange ye-nickel-molybdenum ivamise ukusetshenziswa ngaphansi kwezimo zokunciphisa kakhulu futhi inokwakheka okuphansi kakhulu kwekhabhoni, i-silicon nensimbi kune-Hastelloy B (Ingxubevange B). Izikulufu ezenziwe kule alloy zaziwa nangokuthi yi-UNS N10665 fasteners.

I-Inconel 718 iyingxubevange ye-nickel-chromium precipitation hardening egcina i-ductility enhle namandla aphezulu emazingeni okushisa afika ku-1300°F.

I-Inconel 718 Blind Flanges inikeza amandla aphezulu ngaphandle kokwelashwa kokushisa. Ama-Lap flanges anamandla aphezulu okudonsa, amandla okusebenza, amandla okukhathala namandla akhiqizayo. I-Inconel 718 flanges inezakhiwo ezinhle kakhulu zokumelana nokugqwala okufana ne-oxidation, ukugqwala, i-pitting kanye nokumelana nokugqwala kwe-crevice ukuze kusetshenziswe ezindaweni.

Esinye isici se-HASTELLOY-X fasteners izici zabo ezinhle kakhulu zokwakha kanye nezici zokushisela. Ingakhandwa futhi ingasebenza ngokubandayo ngenxa ye-ductility yayo enhle. Izinhlelo zokusebenza ezijwayelekile ze-Hastelloy x zifaka ukusetshenziswa ezithandweni zezindiza nezingxenye zenqubo yamakhemikhali.

Amazinga okugqwala avame ukusheshiswa emithonjeni ye-aqueous. Kodwa-ke, ngenxa yesisekelo esiqinile se-nickel ye-alloy kanye nesisekelo samakhemikhali e-chromium, izinga lokugqwala kwe-nickel alloy 601 hex bolts liphansi kakhulu.

Izicelo ze-Inconel 600 Nuts and Bolts zingatholakala ezinhlelweni zobunjiniyela ezijwayelekile, izicelo zemboni kawoyela negesi, i-aerospace, olwandle, ukwakhiwa, ukukhiqiza ugesi, nokunye.

Izibophelelo ze-Inconel 601 zingenziwa zibe zonke izinhlobo zamabhawodi, izikulufu, izigxivizo, izigxivizo, amantongomane, amawasha, amadoweli kanye nezinye izinhlobo zamabhawodi ezijwayelekile nezingokwezifiso.

Ingxubevange iyi-ductile futhi yenza kalula izixhumi ze-Inconel 601. Inamandla aphezulu emishini, ukuqina okuhle kanye nokumelana nokugqwala okuhle kakhulu.

I-Hastelloy Nickel Alloy B2 iyingxubevange emincane yamakhemikhali ekwazi ukumelana nokugoba nokuqhekeka kokugqwala kwengcindezi endaweni ethinteke ekushiseni.

Okuqukethwe kwe-chromium, i-molybdenum, i-nickel kanye ne-nitrogen ku-2205 duplex bolt alloy kuthuthukisa izici zayo zomshini. Isib. I-¨C UNS S31803 Fastener alloys iqukethe amanani okulandelela ekhabhoni.

Izikhonkwane ze-Hastelloy B2 zinokumelana nokugqwala okungekuhle ezindaweni ezine-oxidizing ngakho-ke azinconywa ukuthi zisetshenziswe emithonjeni ye-oxidizing noma lapho kukhona usawoti wensimbi noma wethusi njengoba zingabangela ukwehluleka ukugqwala ngokushesha ngaphambi kwesikhathi.

Amabhothi e-nickel alloy 718 nawo asetshenziselwa izizathu zamandla okushisa okuphezulu ekamelweni noma amazinga okushisa ashisa kakhulu okumelana nokugqwala kwesigaba sokuqala okuhlanganisa ukumelana ne-pitting kanye nokugqwala kwe-crevice, ngaphezu kokuqhekeka kwe-polysulfonic acid strain corrosion.

Ama-Inconel 600 Bolts nawo angakhiwa kalula, enziwe ngomshini futhi ashiselwe. Amandla amancane aqinile wezinsimbi angafinyelela ku-825MPa, futhi amandla amancane okukhiqiza angafinyelela ku-620MPa. Eziqine kakhulu izibophelelo eziyindilinga ezisebenza ngamakhaza.

Ngokungafani nensimbi ye-chrome-nickel, le nsimbi ayinciphisi ukumelana nokugqwala ngenxa yemvula ye-carbide. I-Inconel WNR 2.4668 Amantongomane asetshenziswa ezinqubweni ezinhle kakhulu kufaka phakathi izinto zokushisela ezintweni eziningi noma ezincane zokwakheka kwamakhemikhali afanayo, lokhu kusetshenziselwa ukwakhiwa kwamathuluzi okuphatha ama-sulfuric kanye ne-phosphoric acid.

Amabhawodi e-Hastelloy B3 aziwa nangokuthi amabhawodi e-alloy B-3 futhi angatholakala ngaphansi kwe-UNS N10675. Le alloy imelana ngokwedlulele nama-acid ahlanzekile e-hydrobromic, sulfuric kanye ne-hydrochloric. Izimboni eziningi, kufaka phakathi imboni yamakhemikhali, zibheka i-alloy kalula ukuyifaka, futhi i-ductility yayo ivumela ochwepheshe bemishini ukuthi bakheke kalula futhi bashise.

I-Hastelloy B3 studs ifaneleka kuzo zonke izinhlelo zokusebenza ebezidinga ukusetshenziswa kwe-Hastelloy B2 alloy. Ngenxa yokuqina okushisayo okuthuthukisiwe kwamabhawodi skwele e-Hastelloy B3, izinkinga ezihambisana nokukhiqiza izingxenye ze-Hastelloy B2 ziyancipha.

Ngenxa yamandla emishini ye-alloy ephakeme kakhulu, abakhiqizi bezinsimbi ezinezigaba ezimbili banganciphisa isisindo semiklamo yabo ngokunciphisa ingxenye enqamulayo yomkhiqizo wokugcina, babonise enye indlela yokonga izindleko kwamanye amabanga ensimbi engagqwali.

Lezi zinsimbi ziklanywe ngokwekhwalithi yezinto ezingavuthiwe ngokuya ngezindinganiso zikazwelonke nezamazwe ngamazwe, ngaleyo ndlela ziqinisekise ukuqina kwazo kanye nekhwalithi ephezulu.

I-Inconel 718 noma i-Alloy 718 iyibanga elivame ukusetshenziswa eliqinile le-Inconel nickel alloy. Ngenxa yokuqina kwayo kwezulu kanye nezingxenye zayo eziyinhloko ze-nickel ne-chromium, le alloy inokumelana nokugqwala okuhle kakhulu namandla aphezulu ngisho nasezingeni eliphezulu.

I-Hastelloy X Bolts isetshenziswe kakhulu ezingxenyeni zendawo evuthayo yezinjini zomoya njengamapayipi okushintshashintsha, amakamelo omlilo, ama-boom kanye nezibambi zomlilo, kanye nama-afterburners, amapayipi okukhipha umoya nezifudumezi zekhabethe. Le alloy inconywa ekusetshenzisweni kwesithando somlilo wezimboni ngenxa yokumelana kwayo okungavamile ne-oxidation, ukunciphisa kanye nomoya ongathathi hlangothi.

I-Hastelloy X imelana kakhulu nengcindezi yokuqhekeka kokugqwala ekusetshenzisweni kwe-petrochemical. Wonke amafomu omkhiqizo mahle kakhulu ekwakhiweni nasekushiseleni.

Ingxubevange C-276 inokumelana okuhle kakhulu nokugqwala komgodi, ukuqhekeka kokugqwala kwengcindezi kanye nezimo ze-oxidizing ezifika ku-1900¡ãF.

I-Hastelloy C276 Specialty Bolts iyibanga elijwayelekile le-austenitic stainless steel fasteners esekelwe ku-15% chromium kanye ne-nickel engu-57%.
