Intsimbi enganyangekiyo kwi-Corrosion yintsimbi ekhethekileyo yealloyi enokumelana nokugqwesa okugqwesileyo ngokudibanisa izinto zoyilo lwe-alloy ezinganyangekiyo njengobhedu, nickel, kunye nechromium.

Olu hlobo lwentsimbi lunokuxhathisa ukhukuliseko kwimithombo yeendaba eyonakalisa kakhulu.

Ukuxhatshazwa kwayo kwe-corrosion yi-2-8 amaxesha aphakamileyo ngaphezu kwe-carbon steel eqhelekileyo. Njengoko ixesha lokusetyenziswa lisanda, ukuxhathisa ukubola kuya kubonakala ngakumbi.

Intsimbi enganyangekiyo kwi-Corrosion luhlobo lwentsimbi ekhusela umhlwa, nto leyo eyenza ukuba ikwazi ukurusa.

intsimbi enganyangekiyo kumhlwa

Iintsimbi ezingenasicizialloyi ezisekwe kwintsimbi equlathe ubuncinci be-10.5% yechromium, eyaneleyo ukuthintela umhlwa phantsi kweemeko zomoya wegumbi.

Ukongeza kwi-corrosion resistance, i-corrosion resistant steel nayo ineempawu ezintle zoomatshini, iipropati ze-welding, njl.

Ke ngoko, isetyenziswa kakhulu kwishishini lepetrochemical, ubunjineli baselwandle, ishishini lemichiza, ubunjineli bokhuseleko lokusingqongileyo, ubunjineli bamandla kunye nezinye iindawo ukwenza izixhobo ezahlukeneyo, imibhobho, iitanki zokugcina, amacandelo, njl. izixhobo.

Ngomhla we-11 kuMatshi, i-2024, iKhomishini yaseYurophu yakhupha isibhengezo esichaza ukuba yenze isigqibo sokuqala sokulahla ukulahla kwelanga kwi-Corrosion Resistant Steels evela e-China, ithatha isigqibo sokuba ukuba amanyathelo achasene nokulahla ayacinywa, ukulahlwa kweemveliso. ababandakanyekayo kunye nomonakalo wokulahla okubangelwa kumashishini e-EU kuya kuqhubeka okanye kwenzeke kwakhona, ngoko kwagqitywa ukuba kuqhutyekwe nokugcina imisebenzi echasene nokulahla kwiimveliso zaseTshayina ezibandakanyekayo.

Amazinga erhafu enxamnye nokulahlwa yi-17.2% ukuya kuma-27.9%.

Eli tyala libandakanya iikhowudi ze-EU CN (I-Combined Nomenclature) ex 7210 41 00, ex 7210 49 00, ex 7210 61 00, ex 7210 69 00, ex 7212 30 00, ex 7212 50 70 625 ex 7212 50 625 92 00, ex 7225 99 00, ex 7226 99 30

kunye ex 7226 99 70 (EU TARIC codes are 7210 41 00 20, 7210 49 00 20, 7210 61 00 20, 7210 69 00 20, 7212 30 00 6 12 20, 7212 30 00 6 12 20 50 69 20, 7225 92 00 20, 7225 99 00 22, 7225 99 00 92, 7226 99 30 10 kunye 7226 99 70 94).

Ixesha lophando lokulahlwa kweli tyala livela ngoJanuwari 1, 2022 ukuya kuDisemba 31, 2022, kwaye ixesha lophando lomonakalo livela ngoJanuwari 1, 2019 ukuya ekupheleni kwexesha lophando lokulahla.

NgoDisemba 9, 2016, iKomishoni yaseYurophu iqalise uphando oluchasene nokulahlwa kwentsimbi enganyangekiyo kwi-corrosion evela e-China.

Ngomhla we-8 kaFebruwari, i-2018, iKomishoni yaseYurophu yenza isigqibo sokugqibela esichasayo sokulahla intsimbi enganyangekiyo kwi-corrosion evela e-China.

Ngomhla we-8 kaFebruwari, i-2023, iKomishoni yaseYurophu yasungula uphando lokuqala lokulwa nokulahla ukulahla kwelanga malunga nentsimbi enganyangekiyo e-China.

Kukho iimodeli ezahlukeneyo zentsimbi enganyangekiyo kwi-corrosion, eyilwe ngokuyintloko ngokwendawo ezahlukeneyo zesicelo kunye neemfuno zokuxhathisa umhlwa.

Nazi ezinye iimodeli zentsimbi ezixhathisayo kwi-corrosion:

304 sipleyiti yentsimbi engenasiphelo:Le modeli inokumelana ne-corrosion kunye nokusebenza kakuhle, kwaye isetyenziswa kakhulu kukutya, amayeza, iikhemikhali kunye namanye amashishini.

316 ipleyiti yensimbi engenasici:I-Mo element yongezwa kwisiseko se-304 ukuphucula ukuxhathisa kwe-corrosion kunye nokusebenza okuphezulu kweqondo lokushisa, kwaye ifanelekile kwiindawo ezinobungozi ezinobushushu obuphezulu kunye noxinzelelo oluphezulu.

06Cr19Ni10:Le ipleyiti yentsimbi ye-austenitic eneenxalenye eziphambili ziyi-Cr, i-Ni, i-C, njl njl. Inokumelana ne-corrosion elungileyo kunye nokusebenza kokucubungula kwaye isetyenziswa kakhulu kwishishini lemichiza, i-petroleum kunye nezinye iindawo.

022Cr17Ni12Mo2:Le yipleyiti yentsimbi engatyiwayo engagqwaliyo enganyangekiyo eyenziwe nguCr, Ni, Mo, njl njl. Inokumelana nobushushu kwaye isetyenziswa kakhulu kwi-petrochemical, organic chemical, aviation, aerospace kunye nezinye iindawo.

00Cr17Ni14Mo2:Eli licwecwe eliphezulu lensimbi engenasici elenziwe ngu-Cr, i-Ni, i-Mo, njl njl. Inokumelana ne-corrosion egqwesileyo kunye nokumelana nokunxiba kwaye isetyenziswa ngokuqhelekileyo kwimveliso yezixhobo kwishishini lemichiza, i-petroleum kunye nezinye iindawo.
