ʻO ka hao (Fe): ʻo ia ka mea metala kumu o ke kila kila;
ʻO Chromium (Cr): ʻo ia ka mea hana ferrite koʻikoʻi, chromium i hui pū ʻia me ka oxygen hiki ke hana i ka corrosion-resistant Cr2O3 passivation film, ʻo ia kekahi o nā kumu kumu o ke kila kila e mālama ai i ke kūpaʻa corrosion, hoʻonui ka ʻike chromium i ka hiki ke hoʻoponopono kiʻi kiʻi passivation o ke kila, ʻoi aku ka nui o ka chromium ma luna o 12%;
ʻO ke kalapona (C): he mea hoʻokumu austenite ikaika, hiki ke hoʻomaikaʻi maikaʻi i ka ikaika o ke kila, ʻoi aku ka maikaʻi o ke kalapona ma ke kūpaʻa corrosion;
ʻO Nickel (Ni): ʻo ia ka mea hana austenite nui, hiki ke hoʻohaʻahaʻa i ka ʻino o ke kila a me ka ulu ʻana o nā kīʻaha i ka wā hoʻomehana;
ʻO Molybdenum (Mo): ʻo ia ka mea hana carbide, paʻa loa ka carbide i hana ʻia, hiki ke pale i ka ulu ʻana o ka ʻai o ka austenite i ka wā i wela ai, e hoʻemi i ka naʻau superheat o ke kila, ʻo ia hoʻi, hiki i ka molybdenum ke hana i ke kiʻi passivation ʻoi aku ka paʻa a paʻa, no laila. hoʻomaikaʻi maikaʻi i ke kila kuhiliʻole Cl- corrosion kū'ē;
ʻO Niobium, titanium (Nb, Ti): he mea hana carbide ikaika, hiki ke hoʻomaikaʻi i ke kūpaʻa o ke kila i ka corrosion intergranular.Eia nō naʻe, he hopena maikaʻi ʻole ka titanium carbide i ka maikaʻi o ka ʻili o ke kila kila, no laila e hoʻomaikaʻi ʻia ke kila kila me nā koi kiʻekiʻe ma o ka hoʻohui ʻana i ka niobium e hoʻomaikaʻi i ka hana.
ʻO Nitrogen (N): he mea hoʻokumu austenite ikaika, hiki ke hoʻomaikaʻi nui i ka ikaika o ke kila.Akā ʻoi aku ka hopena o ka ʻelemakule o ke kila kila, no laila, ʻoi aku ka maikaʻi o ke kila kila i ka hoʻopaʻa ʻana i nā manaʻo e hoʻomalu pono i ka ʻike nitrogen.
ʻO Phosphorus, sulfur (P, S): he mea ʻino i loko o ke kila kila, hiki ke loaʻa ka hopena maikaʻi ʻole i ka pale ʻana i ka corrosion a me ka stamping o ke kila kila.

Mea a me ka hana
Mea waiwai | Nā hiʻohiʻona |
310S kila kila | 310S kuhiliʻole kila he austenitic chromium-nickel kuhiliʻole kila me ka maikaʻi oxidation kū'ē, corrosion kū'ē, no ka mea, o ka kiʻekiʻe pakeneka o chromium a me nickel, 310S i oi aku ka ikaika kolo, hiki ke hoomau i ka hana ma ke kiʻekiʻe wela, me ka maikai kiʻekiʻe wela kū'ē. |
316L kuhiliʻole kila poepoe bar | 1) He nani a nani hoʻi nā hiʻohiʻona o nā huahana i ʻōwili ʻia. 2) ʻoi aku ka maikaʻi o ka pale ʻana i ka corrosion, ʻoi aku ka maikaʻi o ka pitting resistance, ma muli o ka hoʻohui ʻana o Mo 3) maikaʻi loa kiʻekiʻe wela ikaika; 4) paʻakikī hana maikaʻi loa (mau waiwai magnetic nāwaliwali ma hope o ka hana ʻana) 5) non-magnetic ma ke kūlana hoʻonā paʻa. |
316 kila kila poepoe | Nā hiʻohiʻona: 316 stainless steel ʻo ia ka lua i hoʻohana nui ʻia ma hope o 304, i hoʻohana nui ʻia i ka ʻoihana meaʻai a me nā mea ʻokiʻoki, no ka hoʻohui ʻana o Mo, no laila, ʻoi aku ka maikaʻi o kona pale ʻana i ka corrosion, ke kūpaʻa corrosion o ka lewa a me ka ikaika wela kiʻekiʻe. hoʻohana ʻia i nā kūlana koʻikoʻi;ʻo ka paʻakikī hana maikaʻi (non-magnetic). |
321 kila kila poepoe | Nā hiʻohiʻona: ʻO ka hoʻohui ʻana o nā mea Ti i ke kila 304 e pale ai i ka corrosion palena o ka palaoa, kūpono no ka hoʻohana ʻana i nā mahana o 430 ℃ - 900 ℃.Ma waho aʻe o ka hoʻohui ʻana o nā mea titanium e hōʻemi i ka hopena o ka weld corrosion waiwai ʻē aʻe e like me 304 |
304L kila poepoe kuhiliʻole | ʻO 304L ke kila kila kila he ʻano like ʻole o ka 304 stainless steel me ka haʻahaʻa carbon content a hoʻohana ʻia i nā noi kahi e koi ʻia ai ka wili.ʻO ka haʻahaʻa carbon maʻiʻo liʻiliʻi i ka ua o ka carbide i ka wela i hoʻopili ʻia kokoke i ka weld, hiki ke alakaʻi i ka intergranular corrosion (weld erosion) o ke kila kila ma kekahi mau kaiapuni. |
304 kila kila poepoe | Nā hiʻohiʻona: ʻO 304 stainless steel kekahi o ka chromium-nickel stainless steel i hoʻohana nui ʻia, me ke kūpaʻa corrosion maikaʻi, ke kūpaʻa wela, ka ikaika haʻahaʻa haʻahaʻa a me nā waiwai mechanical.ʻO ka pale ʻana i ka corrosion i ka lewa, inā ʻo ka lewa ʻoihana a i ʻole nā wahi pollution kaumaha, pono e hoʻomaʻemaʻe ʻia i ka manawa e pale ai i ka corrosion. |
Hoʻohana maʻamau
ʻO ke kila kila kila he ākea noi a hoʻohana nui ʻia i nā lako a me nā lako kīhini, ka hana moku, petrochemical, mīkini, lāʻau lapaʻau, meaʻai, mana uila, ikehu, aerospace, etc., ke kūkulu ʻana a me ka hoʻonaninani.ʻO nā lako no ka hoʻohana ʻana i ka wai kai, kemika, ka wai, ka pepa, ka waikawa oxalic, ka mea momona a me nā mea hana ʻē aʻe;paʻi kiʻi, ʻoihana meaʻai, nā mea hana kai, nā kaula, nā koʻokoʻo CD, nā wili, nā nati
Nā Huahana Nui
Hiki ke hoʻokaʻawale ʻia nā kīʻaha kila kila i ʻōwili wela, hoʻopaʻa ʻia a huki ʻia ke anu e like me ke kaʻina hana.Hōʻike ʻia ke kila kila kila ʻōwili wela no 5.5-250 mm.Ma waena o lākou: 5.5-25 mm o ke kila kila kila liʻiliʻi i hoʻolako nui ʻia i loko o nā pūʻulu o nā kaola pololei, i hoʻohana mau ʻia e like me nā kaola kila, nā bolts a me nā ʻāpana mechanical like ʻole;ʻoi aku ka nui o ke kila kila ma mua o 25 mm, i hoʻohana nui ʻia i ka hana ʻana i nā ʻāpana mechanical a i ʻole no nā billet kila seamless.
