chitsulo chosapanga dzimbiri cha ferritic
Chromium 15% mpaka 30%. Kukaniza kwake kwa dzimbiri, kulimba kwake komanso kuwotcherera kumawonjezeka ndi kuchuluka kwa chromium, ndipo kukana kwake kupsinjika kwa chloride kumakhala bwino kuposa mitundu ina yazitsulo zosapanga dzimbiri, monga Crl7, Cr17Mo2Ti, Cr25, Cr25Mo3Ti, Cr28, ndi zina zotere. katundu wake makina ndi ntchito ndondomeko ndi osauka. Amagwiritsidwa ntchito kwambiri m'mapangidwe osamva asidi okhala ndi kupsinjika pang'ono komanso ngati chitsulo chotsutsa-oxidation. Chitsulo chamtunduwu chimatha kukana dzimbiri mumlengalenga, asidi wa nitric ndi mchere wamchere, ndipo ali ndi mawonekedwe abwino okana makutidwe ndi okosijeni komanso kukana kwamafuta pang'ono. Amagwiritsidwa ntchito mu nitric acid ndi zida za fakitale ya chakudya, ndipo angagwiritsidwenso ntchito kupanga zigawo zomwe zimagwira ntchito pa kutentha kwakukulu, monga zigawo za turbine za gasi, ndi zina zotero.

Chitsulo chosapanga dzimbiri cha Austenitic
Lili ndi chromium yoposa 18%, komanso lili ndi 8% nickel ndi molybdenum pang'ono, titaniyamu, nayitrogeni ndi zinthu zina. Kuchita bwino kwathunthu, kugonjetsedwa ndi dzimbiri ndi ma TV osiyanasiyana. Makalasi wamba a austenitic zitsulo zosapanga dzimbiri ndi 1Cr18Ni9, 0Cr19Ni9 ndi zina zotero. Wc ya 0Cr19Ni9 zitsulo ndi zosakwana 0.08%, ndipo nambala yachitsulo imalembedwa kuti "0". Mtundu uwu wachitsulo uli ndi kuchuluka kwa Ni ndi Cr, zomwe zimapangitsa kuti chitsulo chizizizira kutentha.Chitsulo chamtunduwu chimakhala ndi pulasitiki wabwino, kulimba, weldability, kukana kwa dzimbiri ndi zopanda maginito kapena kufooka kwa maginito. kupanga zida zosagwira asidi, monga zotengera zosagwira dzimbiri, mapaipi, zida zosagwira asidi za nitric, ndi zina zambiri, ndipo zitha kugwiritsidwanso ntchito ngati zida zazikulu zazitsulo zosapanga dzimbiri za Austenitic zomwe zimatengera chithandizo chamankhwala, ndiye kuti, chitsulocho chimatenthedwa mpaka 1050-1150 ° C kapena chitsulo chamadzi. austenite kapangidwe.

Austenitic-ferritic duplex chitsulo chosapanga dzimbiri
Ili ndi ubwino wazitsulo zosapanga dzimbiri za austenitic ndi ferritic, ndipo ili ndi superplasticity. Austenite ndi ferrite nkhani iliyonse pafupifupi theka la zitsulo zosapanga dzimbiri. Pankhani ya mpweya wochepa, zomwe zili mu chromium (Cr) ndi 18% ~ 28%, ndipo nickel (Ni) ndi 3% ~ 10%. Zitsulo zina zimakhalanso ndi zinthu za alloying monga Mo, Cu, Si, Nb, Ti, ndi N. Chitsulo chamtunduwu chimakhala ndi zitsulo zosapanga dzimbiri za austenitic ndi ferritic. Poyerekeza ndi ferrite, imakhala ndi pulasitiki yapamwamba komanso yolimba, palibe kutentha kwa chipinda, kumapangitsa kuti ma intergranular corrosion resistance ndi ntchito yowotcherera ikhale yabwino, pokhalabe ndi chitsulo. Poyerekeza ndi zitsulo zosapanga dzimbiri za austenitic, zimakhala ndi mphamvu zambiri komanso zimasintha kwambiri kukana kwa intergranular corrosion ndi chloride stress corrosion. Chitsulo chosapanga dzimbiri cha Duplex chimakhala ndi chitsulo chosapanga dzimbiri komanso chitsulo chosapanga dzimbiri.

Mpweya Woumitsa Chitsulo Chosapanga dzimbiri
Masanjidwewo ndi austenite kapena martensite, ndipo magiredi omwe amagwiritsidwa ntchito kwambiri amvula owumitsa zitsulo zosapanga dzimbiri ndi 04Cr13Ni8Mo2Al ndi zina zotero. Ndizitsulo zosapanga dzimbiri zomwe zimatha kuumitsidwa (kulimbitsa) ndi mvula yamvula (yomwe imadziwikanso kuti kuuma kwa zaka).

Martensitic chitsulo chosapanga dzimbiri
Mkulu mphamvu, koma pulasitiki osauka ndi weldability. Mitundu yomwe imagwiritsidwa ntchito kwambiri yachitsulo chosapanga dzimbiri cha martensitic ndi 1Cr13, 3Cr13, etc., chifukwa cha kuchuluka kwa kaboni, imakhala ndi mphamvu zambiri, kulimba komanso kukana kuvala, koma kukana kwa dzimbiri ndikochepa pang'ono, ndipo kumagwiritsidwa ntchito pamakina apamwamba komanso kukana dzimbiri. Zigawo zina zambiri zimafunikira, monga akasupe, masamba a turbine, ma hydraulic press valves, etc. Mtundu uwu wazitsulo umagwiritsidwa ntchito pambuyo pozimitsa ndi kutentha. Annealing imafunika pambuyo panga ndi sitampu.
