Hoʻohālikelike ma waena o nā paipu kila kila 304H a me 304
— Nā Hiki Hana Hana a me nā Hoʻonā Huahana o Womic Steel
1. ʻIke Huahana
ʻO Womic Steel kahi mea hana alakaʻi o nā paipu kila kila kiʻekiʻe, e hāʻawi ana i nā mea ʻelua304Ha me304nā paipu kila kila e like me nā kūlana honua nui, me:
lASTM A312 / A213 / A269 / A358
lASME SA312 / SA213
lEN 10216-5 / EN 10297-2
lJIS G3459 / ISO 9329-4
lGB/T 14976 / GB/T 13296
ʻO 304H a me 304 he mau kila kila austenitic, akā ua hana ʻia lākou no nā ʻano hana like ʻole—ʻOi aku ka maikaʻi o 304H i ka lawelawe wela kiʻekiʻe, ʻoiaiHāʻawi ʻo 304 i ke kūpaʻa maikaʻi loa i ka pala a me ka hiki ke hoʻopili ʻiama nā noi no nā kumu maʻamau.
2.Ka Hoʻohui Kemika
| ʻElemene | 304 kila kila | 304H kila kila |
| Kalapona (C) | ≤ 0.08% | 0.04% – 0.10% |
| Chromium (Cr) | 18.0% – 20.0% | 18.0% – 20.0% |
| Nikala (Ni) | 8.0% – 11.0% | 8.0% – 11.0% |
| Manganese (Mn) | ≤ 2.00% | ≤ 2.00% |
| Silika (Si) | ≤ 1.00% | ≤ 1.00% |
| ʻO ka phosphorus (P) | ≤ 0.045% | ≤ 0.045% |
| Sulfur (S) | ≤ 0.030% | ≤ 0.030% |
| Naikokene (N) | ≤ 0.10% | ≤ 0.10% |
| Hao (Fe) | Kaulike | Kaulike |
ʻO kaʻoi aku ka nui o ka ʻike kalaponai loko o 304H e hoʻonui i ka carbide precipitation (Cr₂₃C₆), e hoʻomaikaʻi anake kūpaʻa kolo a me ka ikaika wela kiʻekiʻeʻO ka haʻahaʻa o ka ʻike kalapona o 304 he mea kūpono ia nonā hale i hoʻopaʻa ʻiae koi ana i ke kūpaʻa maikaʻi o ka intergranular corrosion.
3. Ka laulā nui a me nā ʻano huahana
Hāʻawi ʻo Womic Steel i nā ʻano paipu kila kila like ʻole i hana ʻia no nā noi ʻoihana, kuhikuhipuʻuone, a me ke kaomi:
Nā Paipu Hana ʻOle:
Anawaena Waho: 6mm - 610mm
Mānoanoa o ka paia: 0.5mm - 50mm
Nā Paipu Weled (RW / TIG / Laser):
Anawaena Waho: 8mm - 1219mm
Mānoanoa o ka paia: 0.5mm - 30mm
Nā Koho ʻē aʻe:
Nā paipu hoʻololi wela, nā paipu U-bend, nā paipu wili ʻia, a me nā paipu i hana ʻia no ka pā kaumaha.
Loa: Loa paʻa a i ʻole a hiki i 18 mika
Nā hoʻopau ʻili: Pickled, annealed, poli ʻia, palaki ʻia
4. Nā Waiwai Mekanika
| Waiwai | 304 kila kila | 304H kila kila |
| Ikaika Hoʻopaʻa (MPa) | ≥ 515 | ≥ 590 |
| Ikaika Hua 0.2% (MPa) | ≥ 205 | ≥ 235 |
| Hoʻolōʻihi (%) | ≥35 | ≥ 35 |
| Paʻakikī (HBW) | ≤192 | ≤192 |
| Ka ikaika o ka haki ʻana o ka kolo (650 ℃, 100,000 hola) | ~55 MPa | ~80 MPa |
ʻIke Koʻikoʻi:
ʻOi aku ka maikaʻi o 304H ma mua o 304 ma lalo o ka hana wela kiʻekiʻe no ka manawa lōʻihi (ma luna o 550 ℃), e kūpono ana nonā mea hoʻomehana hou o ka hale hana mana, nā mea hoʻoponopono petrochemical, a me nā ʻōnaehana hana wela.
5. Nā Koina Hana Wela a me ka Welding
| Palena | 304 | 304H |
| Hoʻoheheʻe ʻana i ka hopena | 1010 – 1065 ℃ | ≥ 1080 ℃ |
| Pane Hana Anu | Maikaʻi loa | Ka nui o ka paʻakikī o ka hana |
| Ka hiki ke hoʻopili ʻia | Maikaʻi loa | Pono i nā metala hoʻopihapiha kalapona kiʻekiʻe aʻe |
| Ka Lapaʻau Wela Ma hope o ka Weld | Koho | Manaʻo ʻia no nā hono koʻikoʻi |
Manaʻo HoʻohuihuiNo 304H, manaʻo ʻo Womic SteelUea hoʻoheheʻe ER308H, me ka kaohi pololei o ka hoʻokomo wela a me ka annealing post-weld no nā hui hilinaʻi kiʻekiʻe i nā ʻōnaehana paipu kiʻekiʻe.
6. Hoʻohālikelike ʻana i ke kūpaʻa ʻana i ka palaho
I loko o nā wahi i loaʻa ka chloride,ʻOi aku ka kiʻekiʻe o ke kū'ē ʻana o ka pitting o 304.
ʻO ka hiki ke hoʻoheheʻe ʻia o 304H ma kahi o50mV haʻahaʻa, e alakaʻi ana i ka hoʻouka kaua kūloko ma mua.
| Kūlana Hoʻāʻo | 304 | 304H |
| Ka nui o ka Cl⁻ 180ppm, 2 mau makahiki | ʻAʻohe leakage | Ua ʻike ʻia ka perforation |
| Ka helu o ka palaho makahiki (mm/makahiki) | ~0.015 mm/makahiki | ~0.020 mm/makahiki |
Hoʻohana304ma nā wahi e koi ana i ka pale maikaʻi loa i ka palaho maʻamau a me ka kūloko e like menā ʻōnaehana hoʻoluʻu moana, ka hana ʻana i ka meaʻai, a i ʻolenā pahu kemika.
7. Hoʻāʻo a me ka Palapala Hōʻoia Kūlana
