Intsimbi engatyiwayo inomlinganiselo ophantsi wechromium oyi-10.5%, nto leyo eyenza ukuba ixhathise ngakumbi kwiindawo ezinolwelo ezidlekayo kunye ne-oxidation. Iyaxhathisa kwi-corrosion kwaye iyaxhathisa, ibonelela ngobuchule obubalaseleyo, kwaye yaziwa kakhulu ngenkangeleko yobuhle bayo. Utyalo-mali lwensimbi engenastainless "luyakwazi ukumelana nomhlwa" xa lusetyenziswa kwindawo elulwelo kunye nomphunga ongaphantsi kwe-1200°F (650°C) kunye "nokumelana nobushushu" xa lusetyenziswa ngaphezu kobu bushushu.
Austenitic steel stainlessibhekisela kwinsimbi engenasici kunye nesakhiwo se-austenitic kwiqondo lokushisa. I-Austenitic steel stainless steel yenye yeeklasi ezintlanu zensimbi engenasici nge-crystalline structure (kunye ne-ferritic, martensitic, duplex kunye nemvula ekhuni). Kwezinye iindawo, i-austentite steel stainless ikwabizwa ngokuba yi-300 series steel stainless steel. Xa intsimbi iqulethe malunga ne-18% ye-Cr, i-8% -25% ye-Ni, kwaye malunga ne-0.1% C, inesakhiwo esizinzile se-austenite. I-Austenitic chromium-nickel steel stainless steel iquka i-18Cr-8Ni edumileyo yentsimbi kunye ne-Cr-Ni ephezulu ye-steel series ephuhliswe ngokudibanisa i-Cr kunye ne-Nick content kunye nokongeza i-Mo, i-Cu, i-Si, i-Nb, i-Ti kunye nezinye izinto kule siseko. I-Austenitic stainless steel ayinayo imagnetic kwaye inokuqina okuphezulu kunye neplastiki, kodwa amandla ayo aphantsi, kwaye akunakwenzeka ukuwomeleza ngokuguqulwa kwesigaba. Inokuqiniswa kuphela ngokusebenza okubandayo. Ukuba izinto ezifana ne-S, i-Ca, i-Se, i-Te zongezwa, ineempawu ezintle zobuchule.
I-Austenitic steel stainless inokuvelisa i-castings. Ukuze kuphuculwe i-fluidity yensimbi etyhidiweyo kunye nokuphucula ukusebenza kokuphosa, ukubunjwa kwe-alloy yensimbi etyhidiweyo kufuneka kulungiswe ngokunyusa umxholo we-silicon, ukwandisa uluhlu lwe-chromium kunye nomxholo we-nickel, kunye nokwandisa umda ophezulu we-sulfure element yokungcola.
I-Austenitic stainless steel kufuneka ibe sisombululo esiqinileyo phambi kokusetyenziswa, ukuze kwandiswe isisombululo esiqinileyo se-precipitates ezahlukeneyo ezifana ne-carbides kwintsimbi kwi-matrix ye-austenite, ngelixa i-homogenizing isakhiwo kunye nokuphelisa uxinzelelo, ukuze kuqinisekiswe ukuxhathisa okugqwesileyo kwe-Corrosion kunye iimpawu zoomatshini. Inkqubo echanekileyo yonyango lwesisombululo kukupholisa amanzi emva kokufudumeza kwi-1050～1150℃ (iindawo ezibhityileyo zinokupholiswa ngumoya). Iqondo lokushisa lonyango lwesisombululo lixhomekeke kwiqondo le-alloying yentsimbi: I-Molybdenum-free okanye i-low-molybdenum imigangatho yentsimbi kufuneka ibe ngaphantsi (≤1100℃), kunye namabakala aphezulu alloyed afana ne-00Cr20Ni18Mo-6CuN, 00Cr25Ni22Mo2N, njl. 1080～1150) ℃).
I-Austenitic 304 ipleyiti yensimbi engenasici, ekuthiwa izisa i-anti-rust eyomeleleyo kunye nokumelana nomhlwa, kwaye ineplastiki egqwesileyo kunye nokuqina, ekulungele ukunyathela kunye nokwenza. Ngoxinaniso lwe-7.93 g / cm3, i-304 insimbi engenasici yinto eqhelekileyo kakhulu, eyaziwa ngokuba yi-18/8 yensimbi engenasici kwishishini. Iimveliso zayo zetsimbi ziyamelana nobushushu obuphezulu kwaye zineempawu ezintle zokucwangcisa, ngoko ke zisetyenziswa kakhulu kwishishini kunye nefenitshala yokuhombisa amashishini kunye nokutya kunye namashishini onyango.
