Amabha Ensimbi Nezinduku

Ibha eyindilinga ye-Duplex yensimbi ye-UNS S31803 isetshenziswa kabanzi kumabha ensimbi engenasici ne-austenitic duplex.

Njengomholi womhlaba jikelele ekuhlinzekweni nasekusabalaliseni insimbi eyindilinga eyi-duplex 2205, insimbi yethu isetshenziswa kuwoyela negesi, amandla aphehlwa ngamanzi, emikhunjini yokucindezela, i-pulp nephepha, izakhi zesakhiwo, amathangi amakhemikhali nezinye izinhlelo zokusebenza eziningi zezimboni.

I-Duplex 2205 iyibanga le-duplex elisetshenziswa kakhulu (i-ferritic\/austenitic) lensimbi engagqwali. Isetshenziswa ngenxa yokumelana kwayo nokugqwala okuhle kakhulu namandla aphezulu.

I-Duplex 2205 inokumelana okuphezulu nokuqhekeka nokugqwala kokuguguleka kunamamaki angenasici e-sus316L austenitic.

I-Duplex Steel S32205 bar stock iyi-ferritic, duplex, austenitic 3% molybdenum, 22% chromium kanye ne-5% - 6% ye-nickel alloy steel stainless steel.

I-Duplex steel UNS S31803, i-UNS S32205 izintambo eziyindilinga nezintambo zisetshenziswa kakhulu kumakhemikhali, uwoyela negesi, umanyolo nezinye izimboni zokufaka isicelo.

Insimbi eyindilinga ye-Duplex 2205 iqukethe i-chromium engu-22%, i-molybdenum engu-3%, ne-nickel engu-5-6%. Ngaphezu kokuqina komthelela okuhle kakhulu namandla aphezulu, futhi inokumelana nokugqwala okuphezulu okujwayelekile, kwendawo kanye nengcindezi.

Imigoqo eyindilinga ye-Duplex 1.4462 iphinde ibe nokunwebeka okuphansi kwe-thermal kanye ne-thermal conductivity ephezulu kanye nokugqwala okuphezulu nezindawo zokukhathala kokuguguleka uma kuqhathaniswa ne-austenite. Ukumelana nokugqwala kwe-duplex 2205 cishe kuphindwe kabili kunezinye izinsimbi ezingenasici ze-austenitic.

2205 ine-solderability enhle. Isisusa sokushisela izinsimbi ezinezigaba ezimbili ukugcina ukumelana nokugqwala, ukuqina namandla ensimbi eyisisekelo endaweni eshiselwe insimbi kanye nendawo ethintekile ekushiseni.

Izinsimbi ze-Duplex nazo zingazibuthe, indawo engasetshenziswa ukuze zihlukanise kalula kusuka kumamaki angenalutho e-austenitic ajwayelekile.

I-Inconel 718 (eyaziwa nangokuthi i-UNS N07718) iyi-superalloy ye-nickel eqina imvula enokumelana nokugqwala okuhle kakhulu namandla kanye nokushisela okuphezulu.

Icishe ifane ne-AISI 4130 chrome-molybdenum alloy steel, kodwa enokuqukethwe kwekhabhoni ephakeme kancane. Uma kuqhathaniswa ne-AISI\/ASTM 4130 alloy steel, i-AISI 4140 insimbi inokuqukethwe kwekhabhoni ephezulu, enikeza amandla aphezulu namandla okuphatha ukushisa, kodwa futhi inokushisela okulinganiselwe.

Ingxubevange kumele ipholiswe ukuze iphathwe ngokushisa ngaphambi kwe-AISI AS F11 Hex Bar. Yonke imingcele yenqubo yokwelapha ukushisa isethwe ukucaciswa, okuhlanganisa uhlobo lokwelashwa kokushisa, ukushisa kwe-austenitization\/solution, kanye nensimbi ye-alloy F11 A182 imigoqo.

Ibha eyisicaba ye-ASTM A182 F12 iyisigaba esiyisicaba esingunxande esinamaphethelo ayisikwele anosayizi abahlukahlukene. Ilungele izinhlelo zokusebenza ezihlukahlukene, ezisatshalaliswa kwezobunjiniyela, ukwakhiwa, ukukhiqiza, ukukhiqiza, izimayini, amagridi akhanyayo kanye nezinye izimboni eziningi.

Ukuguquguquka kwayo kuyisizathu esiyinhloko sokuthi ingasetshenziswa ezimbonini ezihlukahlukene, kanye namandla ayo amahle kakhulu nokubunjwa kwayo.

Sihlinzeka ngezinhlobonhlobo zemigoqo eyindilinga yensimbi ye-ASTM A182 F12 ongakhetha kuzo, futhi le migoqo eyenziwe ngokwezifiso ingenziwa ngokwezifiso ngokuya ngezidingo zamakhasimende. Zisetshenziswa kakhulu kwezezimoto nakweminye imikhakha ngenxa yekhwalithi yazo enhle kakhulu nokusebenza okungenakuqhathaniswa.

Ibha eyindilinga ye-ASTM A182 F12 ivame ukusetshenziswa ezimbonini ezihlukene, njengemboni ye-air-conditioning, imboni ye-aluminium, imboni yamabhayela, imboni yensimbi, imboni kasimende, imboni yezokwakha, njll. Ibha yesitoko se-ASME SA 182 F12 sitholakala ngobukhulu obuhlukahlukene ukuze kuhlangatshezwane nezidingo zamakhasimende ezihlukene.

Ibha yensimbi ye-Alloy F12 inikezela ngezakhiwo ezinhle njengokwakhiwa okuqinile, ukuqina okuzungezile, izinhlobonhlobo zosayizi ongakhetha kuzo, nokuningi.

Ingxubevange yensimbi F12 imigoqo yesikwele ingamelana namazinga okushisa aphezulu kakhulu ngokuguga okuncane komkhiqizo ngisho nangemva kwezinkulungwane zamahora okusebenza,

Ibha yensimbi egoqiwe engu-4140 iyinsimbi ephakathi kwe-carbon alloy enokuqina okuphezulu. Leli banga libuye lisetshenziswe kabanzi ekuqambeni.

Insimbi egoqwe eshisayo engu-4140 nayo inokumelana nokukhathala okuhle kanye nokumelana nomthelela ngemuva kokwelashwa kokushisa.

Abasebenzisi bebha efojiwe ye-SA182 Chrome Moly Gr.f9 abanciki kuphela kuma-coatings angaphandle noma ekuqedeni.

Imigoqo eyindilinga yensimbi ye-ASTM A182 F9 ingenziwa ngokwezifiso ngokuya ngezidingo zamakhasimende. Zisetshenziswa kakhulu kwezezimoto nakweminye imikhakha ngenxa yekhwalithi yazo enhle kakhulu nokusebenza okungenakuqhathaniswa.

Izinsimbi ze-alloy zisetshenziswa ezinhlobonhlobo zezicelo ezidingekayo embonini ye-aerospace namandla (nuclear). Ukwengeza ezinye izakhi kunikeza i-alloy steel amandla engeziwe.

I-alloy steel UNS K12822 imigoqo eyindilinga isetshenziswa kabanzi ezimbonini eziningi ekwenzeni izinhlobo ezahlukene zezingxenye. Sinikeza uhla olugcwele lwensimbi ye-alloy 15Mo3 imigoqo eyindilinga esetshenziswa kabanzi kwezobunjiniyela, ezokwakha nezinye izimboni.

Imigoqo eyindilinga yensimbi ye-DIN 1.7335 iphinde inikeze ezinye izinto ezivelele njengokuqedwa okuphelele, ukuqina kobukhulu, isisindo esilula, umthamo omkhulu wokuthwala umthwalo, impilo ende, ubukhulu obuhle nokunye.

Insimbi eyindilinga eyingxubevange inokuqukethwe okuphezulu kwe-chromium, okuzuzisa ukumelana nokugqwala okumanzi, kanye nokuthuthukisa amandla ayo okushisa okuphezulu kanye nokumelana nezinga lokushisa eliphakeme lokukala.

I-ASTM A 182 Alloy Steel GR F11 Amabha ayindilinga ngokuvamile abhekwa njengaqinile kunama-alloys ensimbi engagqwali, futhi intengo yawo idlala indima ebalulekile ekuthengeni.

Izinsimbi ze-alloy zisetshenziswa ezinhlobonhlobo zezicelo ezidingekayo embonini ye-aerospace namandla (nuclear). Ukwengeza ezinye izakhi kunikeza i-alloy steel amandla engeziwe.

Ngaphandle kwesisombululo sayo esingabizi kakhulu, i-rebar ye-F11-grade iyindlela yokuhlangabezana nokumelana nokugqwala kanye nezidingo zokusebenza kwemishini ezibekwe izimboni ezihlukahlukene.
