ʻO ka papa 304 ka maʻamau "18/8" kulika; ʻo ia ka mea maʻalahi loa a hoʻohana nui ʻia i ke kila kila, i loaʻa i kahi ākea o nā huahana, nā ʻano a me nā hoʻopau ʻana ma mua o nā mea ʻē aʻe. Hollow-ware and saucepans no keia mau mea maʻamau ka hoʻohana 'ana i nā 'ano like 'ole "304DDQ" (Deep Drawing Quality).

ʻAʻole koi ka papa 304L, ka mana kalapona haʻahaʻa o 304, i ka hoʻopili ʻana ma hope o ka weld a no laila ua hoʻohana nui ʻia i nā ʻāpana ana kaumaha (ma kahi o 6mm). ʻO ka papa 304H me kāna ʻike kalapona kiʻekiʻe e loaʻa ka noi ma nā mahana kiʻekiʻe. Hāʻawi ka ʻōnaehana austenitic i kēia mau māka i ka paʻakikī maikaʻi loa, a hiki i nā mahana cryogenic.

Na Waiwai Ki

Kuhi ʻia kēia mau waiwai no ka huahana ʻōwili palahalaha (pāla, pepa a me ka coil) ma ASTM A240/A240M. Ua kuhikuhi ʻia nā waiwai like akā ʻaʻole like no nā huahana ʻē aʻe e like me ka paipu a me ka bar i kā lākou mau kikoʻī.

Huina

Hāʻawi ʻia nā pae haku mele maʻamau no ka papa 304 i ka papa 1.

Papa 1.Nā pae hoʻohui no 304 grade stainless steel

Na Waiwai Mechanical

Hāʻawi ʻia nā ʻano mīkini maʻamau no ka papa 304 stainless steel ma ka papa 2.

Papa 2.Mechanical waiwai o 304 grade kuhiliʻole kila

Pale ʻino

Maikaʻi ma kahi ākea o nā kaiapuni lewa a me nā media corrosive he nui. Ma muli o ka ʻinoʻino ʻana o ka lua a me ka ʻāʻī i loko o nā kaiapuni chloride mahana, a me ke koʻikoʻi i ka pohā ʻino ma luna o 60°C. Manaʻo ʻia he kūpaʻa ʻole i ka wai inu a hiki i ka 200mg/L chlorides i nā mahana ambient, e hōʻemi ana i kahi 150mg/L ma 60°C.

Kū'ē wela

ʻO ke kūpaʻa oxidation maikaʻi i ka lawelawe intermittent i 870 ° C a ma ka lawelawe mau ʻana i 925 ° C. ʻAʻole ʻōlelo ʻia ka hoʻohana mau ʻana o 304 i ka laulā 425-860°C inā he mea nui ka pale ʻana i ka wai ma hope. ʻOi aku ka paʻa o ka papa 304L i ka ua carbide a hiki ke wela i ka pae wela o luna.

ʻOi aku ka ikaika o ka papa 304H i nā mahana kiʻekiʻe no laila hoʻohana pinepine ʻia no nā noi hoʻolālā a me ke kaomi ʻana ma nā mahana ma luna o 500°C a hiki i kahi 800°C. E lilo ana ka 304H i ka sensitized ma ke ana wela o 425-860°C; ʻAʻole kēia he pilikia no nā noi wela kiʻekiʻe, akā e hopena i ka hoʻemi ʻana i ke kūpaʻa aqueous corrosion.

Hoʻomaʻamaʻa Wela

Hoʻoponopono Hoʻoponopono (Annealing) - E wela i ka 1010-1120 ° C a maʻalili wikiwiki. ʻAʻole hiki ke hoʻopaʻakikī ʻia kēia mau māka e ka mālama wela.

wiliwili

ʻO ka weldability maikaʻi loa e nā ʻano fusion maʻamau, me nā metala hoʻopiha a me ka ʻole. AS 1554.6 pre-qualifies wiliwili o 304 me ka Papa 308 a me 304L me 308L kookoo a electrodes (a me ko lakou kiʻekiʻe silicon like). Pono paha nā ʻāpana welded kaumaha ma ka Papa 304 i ka hoʻopili ʻana ma hope o ka weld no ka pale ʻana i ka corrosion kiʻekiʻe. ʻAʻole koi ʻia kēia no ka Papa 304L. Hiki ke hoʻohana ʻia ka papa 321 ma ke ʻano he ʻokoʻa i ka 304 inā makemake ʻia ka wiliwili ʻāpana kaumaha a ʻaʻole hiki ke mālama ʻia ka wela ma hope o ka weld.

Nā noi

Loaʻa nā noi maʻamau:

ʻO nā lako hana meaʻai, ʻo ia hoʻi ma ka hana pia, ka hana waiū a me ka hana waina.

ʻO nā noho kīhini, nā ʻauʻau, nā ʻauʻau, nā lako a me nā mea hana

ʻO ka papa hana hoʻolālā, nā ala hao a me nā ʻoki

ʻO nā pahu kemika, me ka lawe ʻana

Mea Hoʻololi Wela

ʻO nā pale i ulana ʻia a welded paha no ka ʻeli ʻana, ka ʻeli ʻana a me ka kānana wai

Nā mea hoʻopaʻa kaula
