ʻO ka ʻokoʻa nui ma waenaaustenitic stainless steela me ke kila kuhiliʻole ferritic aia i ko lākou mau hale a me nā waiwai.
ʻO Austenitic stainless steel kahi hui e paʻa mau ana ma nā mahana ʻoi aʻe ma mua o 727°C.Hōʻike ia i ka plasticity maikaʻi a ʻo ia ka mea i makemake ʻia no ka hapa nui o nā kila e hana ana i ke kaomi ʻana i nā wela kiʻekiʻe.Eia kekahi, ʻaʻole magnetik ke kila austenitic.
ʻO Ferrite kahi hopena paʻa o ke kalapona i hoʻoheheʻe ʻia i loko o ka α-hao, hōʻailona pinepine ʻia ʻo F. Inkila kohu ʻole, "ferrite" e pili ana i ka hopena paʻa o ke kalapona i loko o ka α-hao, i hōʻike ʻia e kona hikiwawe kalapona.Ma ka lumi wela, hiki iā ia ke hoʻoheheʻe wale i ka 0.0008% kalapona, hiki i ka nui o ka carbon solubility o 0.02% ma 727 ° C, ʻoiai e mālama ana i kahi lattice cubic i hoʻokumu ʻia i ke kino.Hōʻike pinepine ʻia e ka hōʻailona F.
Ma kekahi ʻaoʻao, ferritickila kohu ʻolee pili ana i ke kila kuhiliʻole i haku nui ʻia me ka hale ferritic i ka wā e hoʻohana ai.Loaʻa iā ia ka chromium ma ka laulā o 11% a 30%, e hōʻike ana i kahi ʻano aniani cubic i hoʻokumu ʻia i ke kino.ʻAʻole pili ka ʻike hao o ke kila kuhiliʻole inā ua hoʻokaʻawale ʻia ʻo ia e like me ke kila kila ferritic.
Ma muli o kona ʻano kalapona haʻahaʻa, hōʻike ʻia ke kila kulika ferritic i nā waiwai e like me ka hao maʻemaʻe, me ka plasticity maikaʻi loa a me ka paʻakikī me ka helu elongation (δ) o 45% a 50%.Eia naʻe, haʻahaʻa loa kona ikaika a me ka paʻakikī, me ka ikaika tensile (σb) ma kahi o 250 MPa a me kahi paʻakikī Brinell (HBS) o 80.
