He aha ke kila?
ʻO ke kila he huila o ka hao a ʻo ka mea hoʻohui kumu (nui) ʻo Carbon. Eia nō naʻe, aia kekahi mau ʻokoʻa i kēia wehewehe e like me nā kila interstitial-free (IF) a me ke ʻano 409 ferritic stainless steels, kahi i manaʻo ʻia ai ke kalapona he haumia.
He aha ka Alloy?
Ke hui pū ʻia nā mea ʻokoʻa i nā mea liʻiliʻi i loko o ka mea kumu, ua kapa ʻia ka huahana i loaʻa he alloy o ka mea kumu. No laila, ʻo ke kila he huila hao no ka mea ʻo ka hao ke kumu kumu (mea nui) i ke kila a ʻo ka mea hoʻohui nui ʻo Carbon. Hoʻohui pū ʻia kekahi mau mea e like me Manganese, Silicon, Nickel, Chromium, Molybdenum, Vanadium, Titanium, Niobium, Aluminum, etc.
ʻO Jindalai (Shandong) Steel Group Co., Ltd. he loea a alakaʻi i ka mea hoʻolako kila a me ke kila kila / paipu / coils / papa. E hoʻouna i kāu nīnau a e hauʻoli mākou e nīnau iā ʻoe me ka ʻoihana.
He aha nā ʻano kila like ʻole?
Ma muli o nā haku mele, hiki ke hoʻokaʻawale ʻia ke kila i ʻehā (04) ʻano kumu:
● hao kalapona
● Ke kila kila
● Ke kila kila
● Mea kila kila
1. hao kalapona:
ʻO ke kila kila ka mea i hoʻohana nui ʻia i nā ʻoihana a ʻoi aku ka nui ma mua o 90% o ka nui o ka hana kila. Ma muli o ka ʻike kalapona, ua hoʻokaʻawale ʻia nā kila Carbon i ʻekolu pūʻulu.
● Haʻahaʻa Carbon Steel / Mild Steel
● Medium Carbon Steel
● kila Carbon kiʻekiʻe
Hāʻawi ʻia ka ʻike kalapona ma ka papa ma lalo:
| ʻAʻole. | ʻAno kila kalapona | Pākēneka o Carbon |
| 1 | Haʻahaʻa Carbon Steel/Mid steel | A hiki i ka 0.25% |
| 2 | ʻO ke kila kalapona waena | 0.25% a 0.60% |
| 3 | Ke kila Carbon kiʻekiʻe | 0.60% a 1.5% |
2. Ke kila kila:
ʻO ke kila kila he kila kila i loaʻa ka 10.5% Chromium (Ka liʻiliʻi). Hōʻike ke kila kila i nā waiwai kū i ka corrosion, ma muli o ka hoʻokumu ʻia ʻana o kahi ʻāpana lahilahi o Cr2O3 ma luna o kona ʻili. Ua kapa ʻia kēia ʻāpana ʻo ka papa passive. ʻO ka hoʻonui ʻana i ka nui o Chromium e hoʻonui hou i ka pale ʻana i ka corrosion o ka mea. Hoʻohui pū ʻia me Chromium, Nickel a me Molybdenum e hāʻawi i nā waiwai i makemake ʻia (a i hoʻomaikaʻi ʻia). Loaʻa i ke kila kila ka nui o ka Carbon, Silicon, a me Manganese.
Hoʻohui houʻia nā kila kila;
1. Na kila kila Ferritic
2. Na kila kila Martensitic
3. Austenitic Stainless Steels
4. Duplex Kuhiliʻole
5. Na kila kuhiliʻole (PH).
● ʻO ke kila kila Ferritic: ʻO nā kila Ferritic me nā mea hao-Chromium me nā mea hoʻoheheʻe cubic crystal e pili ana i ke kino (BCC). ʻO kēia mau mea maʻamau a ʻaʻole hiki ke paʻakikī e ka mālama wela akā hiki ke hoʻoikaika ʻia e ka hana anu.
● Austenitic Stainless Steel: Austenitic steels 'oi loa ka corrosion. He non-magnetic a me ka wela-treatable. ʻO ka maʻamau, hiki ke weldable nā kila austenitic.
● ʻO ke kila kila ʻole Martensitic: ʻO nā kila kuhili ʻole Martensitic he ikaika loa a paʻakikī akā ʻaʻole like me ka corrosion e like me nā papa ʻelua ʻē aʻe. ʻO kēia mau kila he mea machinable loa, magnetic, a me ka wela.
● Duplex Stainless Steels: Duplex kuhiliʻole kila i loko o ka lua-phase microstructure i loko o ka palaoa o ka ferritic a me austenitic kuhiliʻole kila (ie Ferrite + Austenite). ʻO nā kila Duplex ma kahi o ʻelua ʻoi aku ka ikaika ma mua o nā kila stainless austenitic a i ʻole ferritic.
● ʻO nā mea hao-hoʻopaʻa i ka ua (PH) ʻO nā kila kila: ʻO ka ua-paʻakiki (PH) Loaʻa i nā kila kila ka ikaika Ultra ma muli o ka paʻakikī o ka ua.
3. Ke kila kila
Ma ke kila kila, hoʻohana ʻia nā ʻāpana like ʻole o nā mea hoʻohuihui, e hoʻokō i nā waiwai i makemake ʻia e like me ka weldability, ductility, machinability, ikaika, hardenability a me ka corrosion resistance, etc.
● Manganese - Hoʻonui i ka ikaika a me ka paʻakikī, hoʻemi i ka ductility a me ka weldability.
● Silicon - Hoʻohana ʻia e like me nā deoxidizer i hoʻohana ʻia i ke kaʻina hana kila.
● Phosphorus - Hoʻonui i ka ikaika a me ka paʻakikī a hoʻemi i ka ductility a me ka notch i ka paʻakikī o ke kila.
● Sulfur –Hoemi i ka ductility, notch impact toughness, a me ka weldability. Loaʻa ma ke ʻano o ka sulfide inclusions.
● Copper - hoʻomaikaʻi i ka pale ʻana i ka corrosion.
● Nickel - Hoʻonui i ka paʻakikī a me ka ikaika o ka hopena o nā kila.
● Molybdenum - Hoʻonui i ka paʻakikī a hoʻonui i ka pale ʻana o nā mea kolo haʻahaʻa.
4. Mea hao hao
Loaʻa i nā kila kila ke kiʻekiʻe o ke kalapona (0.5% a 1.5%). Hāʻawi ka ʻike kalapona kiʻekiʻe i ka paʻakikī a me ka ikaika. Hoʻohana nui ʻia kēia mau kila no ka hana ʻana i nā mea hana a make. Loaʻa i ke kila kila nā ʻano like ʻole o ka tungsten, cobalt, molybdenum, a me vanadium e hoʻonui ai i ka wela a me ke kūpaʻa ʻana, a me ka lōʻihi o ka metala. ʻO kēia ka mea i kūpono loa i nā kila mea hana no ka hoʻohana ʻana i nā mea hana ʻoki a wili.
Hoʻopiha piha ʻia ʻo Jindalai Steel Group me ka waihona waiwai maikaʻi loa o nā huahana kila ma ka ʻoihana. Hiki iā Jindalai ke kōkua iā ʻoe e koho i nā mea kila kūpono e hōʻoiaʻiʻo e loaʻa koke kāu mea e pono ai ke hiki ke kūʻai. Inā kūʻai nā mea kila i kou wā e hiki mai ana, e noi i kahi ʻōlelo. Hāʻawi mākou i kahi mea e loaʻa pololei iā ʻoe nā huahana āu e makemake ai me ka wikiwiki.
