1. Pono Mechanical o ke kila kuhiliʻole
Hāʻawi maʻamau ʻia nā waiwai mechanical i koi ʻia i nā kikoʻī kūʻai no ke kila kuhili.Hāʻawi pū ʻia nā waiwai mīkini liʻiliʻi e nā kūlana like ʻole e pili ana i ka mea a me ke ʻano huahana.ʻO ka hoʻokō ʻana i kēia mau waiwai mechanical maʻamau e hōʻike ana ua hana pono ʻia ka mea i kahi ʻōnaehana kūpono kūpono.Hiki i nā ʻenekinia ke hoʻohana me ka hilinaʻi i nā mea i loko o nā hale e kū pono ana i nā haʻahaʻa hana palekana a me nā pilikia.
ʻO nā waiwai mīkini i ʻōlelo ʻia no nā huahana ʻōwili palahalaha, ʻo ia ka ikaika tensile, hoʻoulu i ke koʻikoʻi (a i ʻole ke koʻikoʻi hōʻoia), elongation a me Brinell a i ʻole Rockwell paʻakikī.ʻO nā koi waiwai no ka bar, tube, pipe and fittings e hōʻike maʻamau i ka ikaika tensile a me ke kaumaha.
2. Hua ikaika o ke kila kila
ʻAʻole like me nā kila māmā, ʻo ka ikaika hoʻohua o ka annealed austenitic stainless steel he haʻahaʻa haʻahaʻa loa o ka ikaika tensile.He 65-70% ka ikaika o ka tensile ikaika o ke kila kila.ʻO kēia helu he 40-45% wale nō i ka ʻohana stainless austenitic.
ʻO ke anuanu e hana wikiwiki a hoʻonui nui i ka ikaika hua.ʻO kekahi mau ʻano o ke kila kila, e like me ka uea hoʻoheheʻe puna, hiki ke hana anu e hāpai i ka ikaika hua i 80-95% o ka ikaika tensile.
3. Ductility o ke kila kila
ʻO ka hui pū ʻana o nā helu paʻakikī hana kiʻekiʻe a me ka elongation / ductility kiʻekiʻe e maʻalahi loa ka hana ʻana i ke kila stainless.Me kēia hui waiwai, hiki ke hoʻoneʻe ʻia ke kila kila i nā hana e like me ke kaha kiʻi hohonu.
Hoʻohālikelike ʻia ka Ductility e like me ka % elongation ma mua o ka haki ʻana i ka wā hoʻāʻo tensile.Loaʻa nā elongation kiʻekiʻe loa i nā kila kuhili ʻole Annealed austenitic.ʻO nā helu maʻamau he 60-70%.
4. Ka paakiki o ke kila kila
ʻO ka paʻakikī ke kū'ē i ke komoʻana o kaʻili waiwai.Ana nā mea ho'āʻo paʻakikī i ka hohonu e hiki ai ke hoʻokuʻu ʻia i ka ʻili o kahi mea.Hoʻohana ʻia nā mīkini Brinell, Rockwell a me Vickers.Loaʻa i kēlā me kēia o kēia mau ʻano indenter ʻokoʻa a me ke ʻano o ka hoʻohana ʻana i ka ikaika i ʻike ʻia.ʻO ka hoʻololi ʻana ma waena o nā unahi like ʻole he mea kokoke wale nō.
Hiki ke hoʻopaʻakikī ʻia nā māka paʻakikī martensitic a me ka ua e ka mālama wela.Hiki ke hoʻopaʻakikī ʻia nā papa ʻē aʻe ma o ka hana anu.
5. Ka ikaika o ke kila kila
ʻO ka ikaika tensile wale nō ka waiwai mechanical pono e wehewehe i ka pahu a me nā huahana uea.Hiki ke hoʻohana ʻia nā māka mea like ma nā ʻano ikaika tensile no nā noi ʻokoʻa loa.ʻO ka ikaika tensile i hāʻawi ʻia o ka pahu a me nā huahana uea pili pono i ka hoʻohana hope ma hope o ka hana ʻana.
Loaʻa i ka uea puna ka ikaika tensile kiʻekiʻe ma hope o ka hana ʻana.Hāʻawi ʻia ka ikaika kiʻekiʻe e ka hana anuanu i loko o nā pūnāwai wili.Inā ʻaʻole kēia ikaika kiʻekiʻe, ʻaʻole e holo pono ka uwea ma ke ʻano he puna.
ʻAʻole koi ʻia kēlā mau ikaika tensile kiʻekiʻe no ka uwea e hoʻohana ʻia i ka hana ʻana a i ʻole ka ulana ʻana.ʻO ka uea a i ʻole ka lāʻau i hoʻohana ʻia ma ke ʻano he mea maka no nā mea hoʻopaʻa, e like me nā bolts a me nā screws, pono e palupalu i ke poʻo a me ke kaula e hoʻokumu ʻia akā ua lawa ka ikaika e hana pono i ka lawelawe.
Loaʻa i nā ʻohana like ʻole o ke kila kila ʻokoʻa ka ikaika tensile a hāʻawi.Hōʻike ʻia kēia mau ikaika maʻamau no nā mea annealed ma ka Papa 1.
Papa 1. Ka ikaika maʻamau no ke kila kuhiliʻole annealed mai nā ʻohana like ʻole

6. Na Pono Kino o ke kila kila
● Ke kū'ē i ka corrosion
● Kūleʻa wela kiʻekiʻe a haʻahaʻa
● Maʻalahi o ka hana ʻana
● Ka ikaika kiʻekiʻe
● Hoʻopiʻi nani
● Ka maʻemaʻe a me ka maʻalahi o ka hoʻomaʻemaʻe
● Ka pōʻai ola lōʻihi
● Hiki ke hana hou
● Haʻahaʻa magnetic permeability
7. Kū'ē kū'ē i ke kila kila
ʻO ke kūpaʻa ʻino maikaʻi kahi hiʻohiʻona o nā mea kila kila.Hiki i nā māka haʻahaʻa haʻahaʻa ke pale i ka corrosion ma nā kūlana maʻamau.Kū'ē nā mea hoʻohui kiʻekiʻe i ka ʻinoʻino e ka hapa nui o nā waikawa, nā ʻoluʻolu alkaline a me nā kaiapuni chloride.
ʻO ke kūpaʻa ʻino o ke kila kila ma muli o kā lākou ʻike chromium.Ma keʻano laulā, loaʻa i ke kila kuhili ka liʻiliʻi ma kahi o 10.5% chromium.Hoʻokumu ka chromium i loko o ka mea hoʻoheheʻe i kahi papa hoʻōla hoʻōla ponoʻī i ka ʻoki ʻokiʻoki i hana ʻia i ka lewa.ʻO ke ʻano hoʻōla ponoʻī o ka papa oxide, ʻo ia ka mea e paʻa mau ke kūpaʻa corrosion me ka nānā ʻole i nā ʻano hana.ʻOiai ke ʻoki ʻia a ʻeha paha ka ʻili, e hoʻōla ʻo ia iā ia iho a mālama ʻia ke kūpaʻa corrosion.
8. Kūleʻa wela loa
Hiki i kekahi mau māka kila kila ke pale i ka scaling a mālama i ka ikaika kiʻekiʻe ma nā wela kiʻekiʻe loa.Mālama nā māka ʻē aʻe i nā waiwai mechanical kiʻekiʻe ma nā mahana cryogenic.
Ka ikaika kiʻekiʻe o ke kila kila
Hiki ke hoʻololi ʻia nā hoʻolālā ʻāpana a me nā ʻano hana i mea e hoʻohana ai i ka hana paʻakikī o nā kila kuhili ʻole i hana ʻia i ke anuanu.ʻO ka hopena o nā ikaika kiʻekiʻe hiki ke ʻae i ka hoʻohana ʻana i nā mea ʻoi aku ka lahilahi, e alakaʻi ana i nā kaumaha haʻahaʻa a me nā kumukūʻai.
ʻO Jindalai Steel Group ka mea hana nui a me ka mea kūʻai aku o ke kila kila kila / pepa / pā / ʻāʻī / paipu.Ke ʻike nei ma mua o 20 mau makahiki o ka hoʻomohala ʻana i nā mākeke honua a loaʻa iā ia nā hale hana 2 me ka mana hana ma luna o 400,000 tons i kēlā me kēia makahiki.Inā makemake ʻoe e loaʻa ka ʻike hou aku e pili ana i nā mea kila kila, e ʻoluʻolu e hoʻokaʻaʻike mai iā mākou i kēia lā a i ʻole e noi i kahi ʻōlelo.
