Koila Kuhili ʻole

ʻO Duplex stainless steel grade 2205 (ʻike pū ʻia ʻo UNS S31803/S32205, ASTM A240 Type 2205, Inox 2205, AISI 318LN, SUS 329J3L, a i ʻole EN 1.4462) he ʻelua-phase (ferritic-austenitic2% alloying3%2% alloy). 2.5–3.5% molybdenum, 4.5–6.5% nickel, a ma kahi o 0.15% nitrogen. Hāʻawi kona microstructure kaulike i kahi hui kūʻokoʻa o ka ikaika kiʻekiʻe a me ke kūpaʻa corrosion maikaʻi loa. No ka laʻana, ʻoi aku ka maʻamau o ka papa 2205 ma kahi o ʻelua ʻelua o ka ikaika o ka 316L stainless steel, e ʻae ana i nā mea hoʻolālā e hoʻohana i nā ʻāpana ʻoi aku ka lahilahi a me ka māmā me ka ʻole o ka hana ʻana.

Hāʻawi maʻamau ka huila ma ke kūlana hoʻonā-annealed (ma ka ASTM A240/A240M) e mālama i kahi hale duplex kūpono. Paʻakikī ka papa 2205 mai nā mahana cryogenic (ma kahi o –50°C) a hiki i +300°C; Ma waho aʻe o kēia pae, hiki ke hana ʻia ka māhele sigma brittle i nā welds. Hana kēia mau waiwai i ka duplex 2205 i koho maikaʻi loa no ke koi ʻana i nā noi e like me ka hana kemika, ka aila a me ke kinoea waho, a me nā wahi kai kahi e koi ʻia ai ka ikaika kiʻekiʻe a me ke kūpaʻa chloride corrosion.

ʻO ka Incoloy 840 kahi mea wela wela i hana nui ʻia me ka nickel a me ka chromium, me ka hao, alumini, a me ka titanium.. Hana ʻia ia no ka wela wela a me nā kūlana lawelawe koʻikoʻi. Mālama ʻo Incoloy 840 i ka ikaika koʻikoʻi ʻoiai i ka wā wela loa a kūʻē i ka oxidation i ka ea a me ka mahu, e kūpono ia no nā kaiapuni koʻikoʻi..

No ke kila kila QN1803 ka ʻohana QN i hoʻomohala ʻia e Qingtuo Group, aia pū kekahi me QN1701, QN1804L, QN1906Mo, a me QN2109Mo. Ma ke ʻano he hanauna hou aʻe, kiʻekiʻe-nitrogen austenitic alloy, QN1803 ua hoʻolālā ʻia e hoʻopaʻa i ka ʻokoʻa ma waena o ka hana a me ke kumukūʻai, e hāʻawi ana i kahi mea hoʻokūkū koʻikoʻi no ke kila kila 304 maʻamau.

ʻO 430 mau wili kila kuhiliʻole ka mea maʻamau a loaʻa i kahi maʻi kalapona kiʻekiʻe, e hoʻokaʻawale ana iā lākou ma ke kila stainless ferritic. ʻAʻole hiki iā lākou ke paʻakikī wikiwiki a makemake i ka mea hoʻomaha i ka wā e mīkini ai. ʻO nā lāʻau lapaʻau maʻamau maʻamau no 430 mau wili kila kila ʻo 2B a me BA. Ma GHT Steel, hoʻohana mākou i nā mīkini kiʻekiʻe e hoʻoponopono i 430 mau wili kila ma o ka ʻōwili anu a me ka ʻōwili wela. Eia hou, ke hāʻawi nei mākou i nā lawelawe kūikawā e hoʻokō i kāu mau pono kikoʻī e pili ana i ka nui, nā māka, a me nā ʻano.

ʻIke ʻia ʻo 316 stainless steel sheet no kāna ʻike nickel kiʻekiʻe, e hiki ai ke hana maʻalahi a kaha kiʻi. Mahalo nui ʻia kēia māka ma ka mākeke no kona kūpaʻa ʻana i ka corrosion, ʻoi aku ka maikaʻi i ka hoʻohālikelike ʻia me nā māka ʻē aʻe.
Ma GHT Steel, hāʻawi mākou i ka ʻeleʻele a me ke keʻokeʻo 316 ʻili kila me ka uhi PVC, me ka hoʻohana ʻana i nā ʻenehana maʻamau a me ka laser e hōʻoia i ka maikaʻi ʻokoʻa.

He austenitic a non-magnetic 301 coil kuhiliʻole i loko o kona kūlana annealed, akā e lilo i magnetic ma hope o ka hana anu. ʻAʻole hiki ke paʻakikī ma o ka mālama ʻana i ka wela. Eia kekahi, hāʻawi mākou i ka hana maʻamau o ka coil i nā ʻano nui, nā ʻano, a me nā māka e hoʻokō i nā pono kikoʻī o kāu mau papahana.

Hana maikaʻi loa ka wili kila kila 201 o GHT Steel i nā kaiapuni paʻakikī, kūpono ia no nā noi i ʻike ʻia i ka corrosion, alkalis, a me nā mea ʻino ʻē aʻe. Hoʻohālikelike ʻia me nā mea ʻē aʻe, hāʻawi ka 201 stainless steel coil i ka ikaika a me ka lōʻihi.
Nā koho kaʻina hana: Hot rolled, cold rolled, etc.
Ka lōʻihi: 100mm a 6000mm.
Ka ikaika tensile: 71,000 MPa.

Ma keʻano he mea hoʻolako kila kila kila nui ma Kina,ʻo Guanghetong (GHT Steel) nā kumukūʻai a me ka hoʻolakoʻana i nā kiʻekiʻe kiʻekiʻe 304 stainless steel coils mai nā inoa kaulana, e hāʻawi ana i ka manawa kūpono a me nā kumukūʻai maikaʻi loa.
