ʻO ke kila kila Austenitic e pili ana i ke kila kila me ka hale austenitic ma ka lumi wela. ʻO Austenitic stainless steel kekahi o nā papa ʻelima o ke kila kila ma ke ʻano crystalline (me ka ferritic, martensitic, duplex a me ka ua paʻakikī). Ke loaʻa i ke kila ma kahi o 18% Cr, 8% -25% Ni, a ma kahi o 0.1% C, he hale austenite paʻa. ʻO Austenitic chromium-nickel stainless steel ka mea kaulana 18Cr-8Ni kila a me ke kila Cr-Ni kiʻekiʻe i hoʻomohala ʻia ma ka hoʻohui ʻana i ka ʻike Cr a me Ni a me ka hoʻohui ʻana iā Mo, Cu, Si, Nb, Ti a me nā mea ʻē aʻe ma kēia kumu. Austenitic kuhiliʻole kila he non-magnetic a he kiʻekiʻe toughness a me ka plasticity, akā, kona ikaika haʻahaʻa, a me ka mea hiki ole ke hooikaika ia ma ka māhele hoʻololi. Hiki ke hooikaika wale ia e ka hana anu. Inā hoʻohui ʻia nā mea e like me S, Ca, Se, Te, loaʻa iā ia nā waiwai maikaʻi o ka machinability.

Nā ʻāpana kaʻa i hoʻolei ʻia e ka hoʻolei kālā ʻana o ke kila kila ʻole o Autenitic
Hiki nō hoʻi ke hoʻoheheʻe ʻia ke kila kila Austenitic, maʻamau ekaʻina hoʻolei kālā. I mea e hoʻomaikaʻi ai i ka wai o ke kila hoʻoheheʻe a hoʻomaikaʻi i ka hana hoʻoheheʻe ʻana, pono e hoʻoponopono ʻia ka hui ʻana o ke kila kila ma ka hoʻonui ʻana i ka ʻike silika, hoʻonui i ka nui o ka chromium a me ka nickel content, a me ka hoʻonui ʻana i ka palena kiʻekiʻe o ka sulfur element haumia.
Pono ke kila kila Austenitic e hoʻopaʻa ʻia ma mua o ka hoʻohana ʻana, i mea e hoʻonui ai i ka hopena paʻa o nā ʻano precipitates e like me ka carbide i ke kila i loko o ka austenite matrix, ʻoiai hoʻi i ka homogenizing i ke ʻano a me ka hoʻopau ʻana i ke kaumaha, i mea e hōʻoia ai i ke kūpaʻa maikaʻi loa a ʻano mekini. ʻO ka ʻōnaehana hoʻoponopono hoʻonā kūpono ʻo ka hoʻoluʻu wai ma hope o ka hoʻomehana ʻana ma 1050～1150 ℃ (hiki i nā ʻāpana lahilahi ke hoʻoluʻu i ka ea). ʻO ka mahana o ka hoʻonā ʻana e pili ana i ke kiʻekiʻe o ka hoʻohui ʻana o ke kila: ʻoi aku ka haʻahaʻa o ka molybdenum-free a i ʻole ka haʻahaʻa haʻahaʻa haʻahaʻa (≤1100 ℃), a ʻoi aku ka kiʻekiʻe o nā māka alloyed e like me 00Cr20Ni18Mo-6CuN, 00Cr25Ni22Mo2N, etc. 1080～1150) ℃).
ʻO Austenitic 304 ke kila kila kila, ka mea i ʻōlelo ʻia e lawe mai i ka anti-rust a me ka pale ʻana i ka corrosion, a he plasticity maikaʻi loa a me ka paʻakikī, kahi kūpono no ka hoʻopaʻa ʻana a me ka hana ʻana. Me ka mānoanoa o 7.93g/cm3, 304 stainless steel he kila kila maʻamau, ʻike ʻia ʻo 18/8 stainless steel i ka ʻoihana.
