Kutshanje, umgangatho wesizwe we-GB/T20878-2024 "amaBanga eStainless Steel kunye neMichiza yeMichiza", ehlelwe yiMetallurgical Industry Information Standards Research Institute kwaye yathatha inxaxheba yiFujian Qingtuo Special Steel Technology Research Co., Ltd. kunye nezinye iiyunithi, yakhululwa kwaye iya kuthanda iya kuphunyezwa ngoFebruwari 1, 2025. . Emva kweminyaka ephantse ibe mithandathu yemizamo engapheliyo, iQingtuo Group ngokuzimeleyo iphuhlise i-nitrogen-equlethe i-austenitic eyomeleziweyo kakhulu ye-stainless steel stainless series series, kuquka i-S35250 (QN1701), i-S25230 (QN1801), i-S35657 (QN1803), i-S35656 (i-QN380 eyahlukileyo), i-S35656 (QN3808) amanqanaba okumelana nokubola okufana ne-QF1804), i-S35706 (QN2008), i-S35886 (QN1906) kunye ne-S35887 (QN2109) ibandakanyiwe kulo mgangatho, ukutyebisa ulwakhiwo lwensimbi engenasici kunye nokubonelela amandla aphezulu, ukukhanya, kunye nokumelana nokukhula okuphezulu kwintsimi ye-corrosion. izakhiwo zokuthwala umthwalo. Isicwangciso sofezekiso lweentlobo zetsimbi ezingenasici ezinokhuseleko oluphezulu kunye neendleko ezifanelekileyo.
I-S35656 (QN1804) ixhomekeke kwi-corrosion resistance resistance, i-weldability kunye ne-low-temperature mechanical properties ukuba ifakwe kwi-GB/T150.2-2024 "Ii-Pressure Vessels Part 2: Materials" kunye ne-GB/T713.7-2023 “Steel Plate and Steel kwiZixhobo zoxinzelelo” NgeCandelo lesi-7: Intsimbi eNcinci kunye neNtsimbi eNgamelanga ubushushu” kunye neminye imigangatho emibini yelizwe enxulumene nemikhumbi yoxinzelelo. Kule minyaka imbalwa idlulileyo, i-QN series steel stainless steel yenze i-stainless chain chain kwaye isetyenziswe kwiibhetshi kwiindawo ezininzi zemarike yesakhiwo esithwala umthwalo onjengobunjineli betonela kaloliwe ohamba ngesantya esiphezulu, izakhiwo ezisele zilungisiwe, ubunjineli bendlela engaphantsi komhlaba, amandla, ubunjineli bolwandle kunye nobunjineli bolwandle. iinqanawa zoxinzelelo.
Electropolishingyinkqubo yokugqiba i-electrochemical esusa uluhlu oluncinci lwezinto ezivela kwintsimbi yentsimbi, ngokuqhelekileyo insimbi engenasici okanye i-alloys efanayo. Inkqubo ishiya umphezulu omenyezelayo, ogudileyo, ococeke kakhulu.
Kwaziwa njengeukupolisha kwe-electrochemical, ipolishi ye-anodicokanyeelectrolytic polishing, i-electropolishing iluncedo ngokukhethekileyo ekupholiseni nasekususeni iindawo ezinobuthathaka okanye ezinejometri ezintsonkothileyo. I-Electropolishing iphucula ukugqitywa komphezulu ngokunciphisa uburhabaxa bomphezulu ukuya kuthi ga kwi-50%.
I-Electropolishing inokucingelwa njengeukuguqula i-electroplating. Esikhundleni sokongeza i-coating encinci yee-ion zetsimbi ezihlawulweyo, i-electropolishing isebenzisa umsinga wombane ukunyibilikisa umaleko obhityileyo wee-ion zetsimbi kwisisombululo se-electrolyte.
I-Electropolishing yensimbi engenasici yinto eqhelekileyo yokusetyenziswa kwe-electropolishing. Electropolished stainless steel inomtyino ogudileyo, umenyezelayo, ococekileyo okwaziyo ukumelana nokudleka. Nangona phantse nayiphi na isinyithi iya kusebenza, iintsimbi eziqhelekileyo ze-electropolished ziyi-300- kunye ne-400-series stainless steel.
Ukugqitywa kwe-electroplating kunemigangatho eyahlukeneyo yokusetyenziswa kwizicelo ezahlukeneyo. Ezi zicelo zifuna uluhlu oluphakathi lokugqiba. Ukucocwa kombane yinkqubo ngoburhabaxa obupheleleyo boMbhobho weNtsimbi oyi-Electropolished Stainless Steel uyancitshiswa. Oku kwenza ukuba imibhobho ichaneke ngakumbi ngokwemilinganiselo kwaye i-EP Pipe inokufakwa ngokuchanekileyo kwiinkqubo ezibuthathaka njengeizicelo zoshishino lwamayeza.
Sinezixhobo zethu zokupholisa kwaye sivelise iityhubhu zokupholisha i-electrolytic ezihlangabezana neemfuno zemimandla eyahlukeneyo phantsi kwesikhokelo seqela lobugcisa laseKorea.
I-EP Tube yethu kwi-ISO14644-1 Iklasi ye-5 yeemeko zegumbi ezicocekileyo, ityhubhu nganye ihlanjululwaukucoceka okuphezulu kakhulu (UHP)nitrogen kwaye ke capped kwaye kabini bagged. Isiqinisekiso esilungele imigangatho yemveliso yetyhubhu, ukwakheka kweekhemikhali, ukulandeleka kwemathiriyeli, kunye nobuninzi boburhabaxa bomphezulu bubonelelwe kuzo zonke izinto.
