Loaʻa i ka Nitrogen i hoʻopaʻa ʻia i ka austenitic stainless steel QN series huahana i hoʻokomo ʻia i loko o ka pae aupuni GB/T20878-2024 a hoʻokuʻu ʻia.

I kēia mau lā, ua hoʻokuʻu ʻia ke kūlana aupuni GB / T20878-2024 "Stainless Steel Grades and Chemical Compositions", i hoʻoponopono ʻia e ka Metallurgical Industry Information Standards Research Institute a ua komo ʻia e Fujian Qingtuo Special Steel Technology Research Co., Ltd. a me nā ʻāpana ʻē aʻe. e hoʻokō ʻia ma Pepeluali 1, 2025. . Ma hope o ʻeono mau makahiki o ka hoʻoikaika ʻole ʻana, ua hoʻomohala kūʻokoʻa ʻo Qingtuo Group i ka moʻo QN austenitic stainless steel i hoʻoikaika nui ʻia, me S35250 (QN1701), S25230 (QN1801), S35657 (QN1803), S35656 (QN1808), S35656 (QN5308), S35656 (QN5308 ʻokoʻa). Ua hoʻokomo ʻia nā pae kūʻē corrosion e like me QF1804), S35706 (QN2008), S35886 (QN1906) a me S35887 (QN2109) i loko o kēia maʻamau, e hoʻonui ana i ke ʻano o ke kila kila a hāʻawi i ka ikaika kiʻekiʻe, māmā, a me ke kūpaʻa kiʻekiʻe o ka corrosion. nā hale lawe ukana. ʻO ka hoʻolālā hoʻokō o nā ʻano ʻano kila kila me ka palekana kiʻekiʻe a me ke kumu kūʻai. 

Ke hilinaʻi nei ʻo S35656 (QN1804) i kona kūpaʻa corrosion maikaʻi loa, weldability a me nā waiwai mechanical haʻahaʻa haʻahaʻa e hoʻokomo ʻia i loko o GB / T150.2-2024 "Pressure Vessels Part 2: Materials" a me GB / T713.7-2023 "Steel Plate and Steel no ka Mea Paʻi Paʻi "Me ka Māhele 7: Ke kila kila a me ke kila wela" a me nā kūlana aupuni ʻelua e pili ana i nā moku kaomi. I nā makahiki i hala iho nei, ua hoʻokumu ʻo QN series stainless steel i kahi kaulahao ʻoihana paʻa a ua hoʻohana ʻia i nā pūʻulu i loko o nā māla mākeke ukana e like me ka ʻenekinia tunnel kiʻekiʻe kiʻekiʻe, nā hale prefabricated, subway engineering, ikehu, ʻenekinia moana a me moku kaomi.

ElectropolishingHe kaʻina hana hoʻopau electrochemical e hoʻoneʻe i kahi ʻāpana lahilahi o ka mea mai kahi ʻāpana metala, maʻamau he kila kuhiliʻole a i ʻole nā ​​​​mea like. Ke waiho nei ke kaʻina hana i kahi ʻālohilohi, ʻoluʻolu, ultra-maʻemaʻe.

Also ikehoʻolāʻau electrochemical, poli anodica i ʻolehoʻopololei electrolytic, He mea pono loa ka electropolishing no ka poli a me ka wehe ʻana i nā ʻāpana palupalu a i ʻole nā ​​geometries paʻakikī. Hoʻomaikaʻi ʻo Electropolishing i ka hoʻopau ʻana i ka ʻili ma ka hōʻemi ʻana i ka roughness o ka ʻili a hiki i 50%.

Hiki ke noʻonoʻo ʻia ka electropolishinghoʻohuli electroplating. Ma kahi o ka hoʻohui ʻana i kahi uhi lahilahi o nā ion metala i hoʻopiʻi maikaʻi ʻia, hoʻohana ka electropolishing i ke au uila e hoʻoheheʻe i kahi ʻāpana lahilahi o nā ion metala i loko o kahi hopena electrolyte.

ʻO ka electropolishing o ke kila kila ka hoʻohana maʻamau o ka electropolishing. ʻO ke kila kila kila i hoʻoheheʻe ʻia, ʻālohilohi, hoʻomaʻemaʻe ultra-maʻemaʻe e kūʻē i ka corrosion. ʻOiai ʻaneʻane e hana nā metala, ʻo nā metala electropolished maʻamau he 300- a me 400-series stainless steel.

ʻO ka hoʻopau ʻana o ka electroplating he mau kūlana like ʻole no ka hoʻohana ʻana i nā noi like ʻole. Pono kēia mau noi i ka laulā waena o ka hoʻopau. ʻO ka Electropolishing kahi kaʻina hana me ka hoʻohaʻahaʻa loa o ka Electropolished Stainless Steel Pipe. ʻO kēia ka mea i ʻoi aku ka pololei o nā paipu i nā ana a hiki ke hoʻokomo ʻia ka EP Pipe me ka pololei i nā ʻōnaehana koʻikoʻi e like me kaʻoihana ʻoihana lāʻau lapaʻau.

Loaʻa iā mākou kā mākou mau mea hana polishing ponoʻī a hana i nā paipu electrolytic polishing e hoʻokō i nā koi o nā kahua like ʻole ma lalo o ke alakaʻi ʻana o ka hui ʻenehana Korea.

ʻO kā mākou EP Tube ma ISO14644-1 Class 5 nā kūlana lumi maʻemaʻe, hoʻomaʻemaʻe ʻia kēlā me kēia paipumaʻemaʻe kiʻekiʻe loa (UHP)nitrogen a laila uhi ʻia a ʻeke pālua. Hāʻawi ʻia ka palapala hōʻoia e hoʻokō ai i nā kūlana hana o ka paipu, haku mele mele, hiki ke ʻike i nā mea, a me ka ʻili o ka ʻili kiʻekiʻe no nā mea āpau.
