ʻO ka pāpaʻi kalapona ʻino maikaʻi loa

ʻO ka wehewehe pōkole:

ʻO ka pā kila kila ka ʻili maʻemaʻe, ka plasticity kiʻekiʻe, ka paʻakikī a me ka ikaika mechanical, a kūʻē i ka corrosion o ka waika, alkaline gas, solution a me nā media ʻē aʻe.He ʻano kila kila ʻaʻole maʻalahi i ka ʻōpala, akā ʻaʻole ia he ʻeleʻele loa.ʻO ka pā kila kila e pili ana i ka pā kila kūʻē i ka corrosion o nā media palupalu e like me ka lewa, ka mahu a me ka wai, ʻoiai ʻo ka pā hao kūpaʻa e pili ana i ka pā kila i kū i ka corrosion o nā media etching kemikal e like me ka waikawa, ka alkali a me ka paʻakai.He moʻolelo ʻoi aku ka nui o ka pā kila kila ma mua o hoʻokahi kenekulia mai kona puka ʻana mai i ka hoʻomaka ʻana o ke kenekulia 20.

Ka wehewehe huahana

ʻO ka pā kila kila ka inoa maʻamau o ka pā kila kila a me ka pā kila kūpaʻa wai.Ua puka mai i ka hoʻomaka ʻana o kēia kenekulia.ʻO ka hoʻomohala ʻana i ka pā kila kila i waiho i kahi kumu waiwai nui a me ka ʻenehana no ka hoʻomohala ʻana i ka ʻoihana hou a me ka holomua ʻepekema a me ka ʻenehana.Nui nā ʻano pā kila kuhili ʻole me nā waiwai like ʻole.

ʻano huahana

Ua hoʻokumu mālie ʻo ia i kekahi mau ʻāpana i ke kaʻina hana.E like me ka hale, ua maheleia i eha waeʻano: austenitic kuhiliʻole kila pā, martensitic kuhiliʻole kila pā (me ka precipitation hardening kuhiliʻole kila pā), ferritic kuhiliʻole kila pā, a me austenitic me ferritic duplex kuhiliʻole papa?

E like me ka hana kemika nui i loko o ka pā kila a i ʻole kekahi mau hiʻohiʻona i loko o ka pā kila, ua māhele ʻia i loko o ka chromium stainless steel plate, chromium nickel stainless steel plate, chromium nickel molybdenum stainless steel plate, low-carbon stainless steel plate, high molybdenum. pā kila kuhiliʻole, kiʻekiʻe-maʻemaʻe kuhili ʻole pā, etc.
Wahi a nā hiʻohiʻona hana a me ka hoʻohana ʻana i nā pā kila, ua māhele ʻia lākou i ka nitric acid resistant stainless steel plate, sulfuric acid resistant stainless steel plate, pitting corrosion resistant stainless steel plate, stress corrosion resistant stainless steel plate, high-strengt stainless steel plate, etc.
Wahi a nā hiʻohiʻona hana o ka pā kila, ua māhele ʻia i loko o ka pā haʻahaʻa haʻahaʻa kuhili ʻole, non-magnetic stainless steel plate, free cutting stainless steel plate, superplastic stainless steel plate, etc. e hoʻokaʻawale i ka pā kila e like me nā hiʻohiʻona o ka pā kila, nā ʻano hana kemika o ka pā kila a me ka hui pū ʻana o nā mea ʻelua.Hoʻokaʻawale ʻia ʻo ia i loko o ka pā kila kuhiliʻole martensitic, ka pā kila kuhiliʻole ferritic, ka pā kila austenitic, ka pā kila kila duplex a me ka pā paʻakikī paʻakikī o ka ua, a i ʻole i loko o ka chromium kuhiliʻole pā a me ka nickel stainless steel plate.

Hoʻohana maʻamau

ʻO ka pulupulu a me ka pepa pepa, ka mea hoʻololi wela, nā mea mīkini, nā mea pena, nā mea hana kiʻiʻoniʻoni, pipeline, nā mea waho o nā hale ma nā kahakai, etc.

ʻO ke kūpaʻa ʻino

ʻO ke kūpaʻa ʻino o ke kila kila ma muli o kāna haku mele (chromium, nickel, titanium, silicon, aluminika, manganese, etc.) a me ka hale o loko.

Hoʻomākaukau

E like me ke ʻano o ka hoʻomākaukau ʻana, hiki ke hoʻokaʻawale ʻia i ka ʻōwili wela a me ka ʻōwili anuanu.E like me nā hiʻohiʻona o ke kila kila, hiki ke hoʻokaʻawale ʻia i 5 mau ʻano: Austenitic type, AUSTENITIC FERRITIC type, ferritic type, martensitic type a me precipitation hardening type.
ʻO ka pā kila kila ka ʻili maʻemaʻe, ka plasticity kiʻekiʻe, ka paʻakikī a me ka ikaika mechanical, a kūʻē i ka corrosion o ka waika, alkaline gas, solution a me nā media ʻē aʻe.He ʻano kila kila ʻaʻole maʻalahi i ka ʻōpala, akā ʻaʻole ia he ʻeleʻele loa.Hiki i ka pā kila kila ke kū'ē i ka corrosion maʻamau e like me ka nickel chromium alloy 304. ʻO ka hoʻomehana lōʻihi i ka pae wela o ka chromium carbide hiki ke hoʻopili i ke kūpaʻa corrosion o nā alloys 321 a me 347 i nā media corrosive paʻakikī.

Palapala noi

Hoʻohana nui ia no nā noi wela kiʻekiʻe.Pono nā noi wela kiʻekiʻe i ke kūpaʻa sensitization ikaika e pale i ka corrosion intergranular ma nā haʻahaʻa haʻahaʻa.

Kaʻina hana o ka pā kila kuhiliʻole

No ke kila stainless annealed, e wehe mua i ka ʻili ʻeleʻele me ka kemika ng-9-1, a no ka poʻe me ka ʻaila hinu, e wehe mua i ka ʻaila me ka nz-b degreasing king → holoi wai → electrolytic fine polishing (hoʻohana pololei ʻia kēia hopena ma ke ʻano he hana. wai, ʻo ka mahana he 60 ~ 80 ℃, kau ʻia ka mea hana me ka anode, ʻo ka Da o kēia manawa he 20 ~ 15A / DM2, a ʻo ka cathode ke alakaʻi antimony alloy (me ka antimony 8%) manawa: 1 ~ 10 mau minuke, Polishing → holoi wai → wehe kiʻiʻoniʻoni me 5 ~ 8% hydrochloric acid (ke ana wela lumi: 1 ~ 3 kekona) → holoi wai → puhi maloʻo.
