He kila mākēneki?

ʻO ke kila kila ke ʻano o ke kila kila i loaʻa ka hao ma ke ʻano he mea nui, me ka chromium, nickel, a me nā mea ʻē aʻe. ʻO ke kila kuhiliʻole ka magnetic a ʻaʻole paha ma muli o kona haku mele ʻana a me ke ʻano o ka hana ʻana. Aia nā kila kila kila a me nā mea kila ʻole, e pili ana i ka haku mele.

He aha kakila kohu ʻole?

ʻO ke kila kila he mea hoʻoheheʻe kūʻokoʻa o ka hao, chromium, a me nā mea ʻē aʻe e like me ka nickel, molybdenum, a i ʻole manganese. Kapaʻiaʻo ia he "stainless" no ka mea e kū'ē ana ia i kaʻeleʻele a me kaʻinoʻino, e lilo ia i mea koho nui no nāʻano likeʻole e pili ana i ka lōʻihi a me ke kū'ēʻana i nā mea pili i ke kaiapuni. silika, kalapona, nitrogen, a me manganese. Pono e haku ʻia me ka liʻiliʻi he 10.5% chromium a ʻoi aku ka nui o 1.2% kalapona e ʻike ʻia he kila kila.

Nā ʻano ʻano kila kila

Hiki mai ke kila kila ma nā ʻano like ʻole a i ʻole nā ​​māka, kēlā me kēia me kona haku mele ponoʻī a me nā waiwai. Hoʻokaʻawale ʻia kēia mau māka i ʻelima mau ʻohana nui:

1.Austenitic Stainless Steel (300 Series):ʻO ke kila kila Austenitic ka mea maʻamau a ʻike ʻia no kāna mau waiwai non-magnetic, kūpaʻa maikaʻi i ka corrosion, a me ka formability maikaʻi.

2.ʻO Ferritic Stainless Steel (400 Series):ʻO ke kila kuhiliʻole Ferritic he mea māke a maikaʻi kona kūʻē ʻana i ka ʻino, ʻoiai ʻaʻole ia e like me ke kila kila austenitic. Aia nā māka maʻamau he 430 a me 446.

3.Ke kila kila ʻole Martensitic (400 Series):ʻO ke kila kuhiliʻole Martensitic he magnetic a maikaʻi ka ikaika a me ka paʻakikī. Hoʻohana ʻia ia i nā noi i mea nui ke kūpaʻa a me ka paʻakikī. ʻO nā māka maʻamau ka 410 a me 420.

4.Duplex Stainless Steel:Hoʻohui ka Duplex stainless steel i nā waiwai o nā austenitic a me ka ferritic stainless steel. Hāʻawi ia i ke kūpaʻa corrosion maikaʻi a me ka ikaika kiʻekiʻe. ʻO nā māka maʻamau ka 2205 a me 2507.

5.ʻO ka ua-hoʻopaʻa hao hao:Hiki ke hoʻomaʻamaʻa ʻia ke kila kila e hoʻopaʻa i ka ua no ka loaʻa ʻana o ka ikaika kiʻekiʻe a me ka paʻakikī. Loaʻa nā māka maʻamau 17-4 PH a me 15-5 PH.

He aha ka mea e hana ai i ke kila kuhiliʻole?

Hiki i ke kila kila ke ʻano magnetic a i ʻole ka magnetic, ma muli o kāna ʻano kikoʻī a me ka microstructure. ʻO ke kila kila kila o ke kila kila ma muli o kona ʻano crystalline, ke alo o nā mea alloying, a me kāna mōʻaukala hana. ʻAʻole maʻamau ke kila kila Austenitic, ʻoiai ʻo ka ferritic a me ka martensitic stainless steel ka mea maʻamau. Eia nō naʻe, he mea nui e hoʻomaopopo he hiki ke hoʻololi i loko o kēlā me kēia ʻāpana e pili ana i nā haku mele a me nā kaʻina hana.
