Zitsulo zosapanga dzimbiri nthawi zambiri amatanthawuza zitsulo zosapanga dzimbiri komanso zitsulo zosagwira asidi. Kumayambiriro kwa zaka za m'ma, chitukuko cha mbale zosapanga dzimbiri zitsulo anaika zofunika zakuthupi ndi luso maziko chitukuko cha makampani amakono ndi kupita patsogolo sayansi ndi luso. Pali mitundu yambiri yazitsulo zosapanga dzimbiri zosapanga dzimbiri zokhala ndi katundu wosiyanasiyana, ndipo pang'onopang'ono zapanga magulu angapo akuluakulu pakupanga chitukuko. Malinga ndi kapangidwe ka bungweli, lagawidwa m'magulu anayi: mbale yachitsulo yosapanga dzimbiri ya austenitic, mbale yachitsulo yosapanga dzimbiri ya Martens (kuphatikiza mvula yolimba yachitsulo chosapanga dzimbiri), mbale yachitsulo chosapanga dzimbiri, ndi mbale yachitsulo yosapanga dzimbiri ya austenite kuphatikiza ferrite duplex.

Zomwe zimapangidwira kapena zinthu zina zomwe zili mu mbale yachitsulo zimayikidwa mu mbale ya chrome, nickel nickel zitsulo zosapanga dzimbiri, chrome faifi tambala molybdenum zitsulo zosapanga dzimbiri ndi mbale yotsika ya carbon zosapanga dzimbiri, mbale yachitsulo yosapanga dzimbiri ya molybdenum, mbale yachitsulo yosapanga dzimbiri ya molybdenum, mbale yachitsulo chosapanga dzimbiri. ndi zina zotero. Malinga ndi mawonekedwe a ntchito ndi gulu ntchito mbale zitsulo, iwo anawagawa nitric acid kugonjetsedwa zosapanga dzimbiri mbale, asidi sulfuric kugonjetsedwa zosapanga dzimbiri mbale, pitting kugonjetsedwa zosapanga dzimbiri mbale, nkhawa dzimbiri kugonjetsedwa ndi mbale zitsulo zosapanga dzimbiri, mkulu mphamvu zosapanga dzimbiri mbale, etc. Wosankhidwa molingana ndi magwiridwe antchito a mbale yachitsulo, amagawidwa kukhala mbale yachitsulo chosapanga dzimbiri, yopanda maginito yachitsulo chosapanga dzimbiri, mbale yachitsulo yosapanga dzimbiri yaulere, mbale yapamwamba ya pulasitiki yosapanga dzimbiri ndi zina zotero.

Njira yamagulu yomwe imagwiritsidwa ntchito nthawi zambiri imayikidwa molingana ndi mawonekedwe a chitsulo chachitsulo ndi kapangidwe kake kachitsulo kachitsulo ndi kuphatikiza ziwirizo. Nthawi zambiri, imagawidwa m'magawo a chitsulo chosapanga dzimbiri, mbale yachitsulo yosapanga dzimbiri, mbale yachitsulo yosapanga dzimbiri ya austenitic, mbale yachitsulo yosapanga dzimbiri komanso mvula yowumitsa chitsulo chosapanga dzimbiri, kapena kugawidwa m'magulu awiri: mbale ya chrome yosapanga dzimbiri ndi mbale yachitsulo yosapanga dzimbiri. Zomwe zimagwiritsidwa ntchito kwambiri Zomwe zimagwiritsidwa ntchito: zosinthira kutentha zamakina ndi zida zopangira mapepala, zida zamakina, zida zopaka utoto, zida zopangira mafilimu, mapaipi, zida zakunja zanyumba zam'mphepete mwa nyanja, ndi zina zambiri.

Chitsulo chachitsulo chosapanga dzimbiri chimakhala ndi malo osalala, mapulasitiki apamwamba, kulimba ndi mphamvu zamakina, ndipo sagwirizana ndi dzimbiri ndi asidi, mpweya wa alkaline, zothetsera ndi zina. Ndi chitsulo cha alloy chomwe sichichita dzimbiri mosavuta, koma sichikhala ndi dzimbiri.

Kukana dzimbiri
Chitsulo chosapanga dzimbiri chimatha kupirira dzimbiri wamba mofanana ndi wosakhazikika nichrome 304. Kutentha kwa nthawi yaitali mu kutentha kwa chromium carbide kungakhudze ma aloyi 321 ndi 347 muzinthu zowonongeka zowonongeka. Amagwiritsidwa ntchito kwambiri pakugwiritsa ntchito kutentha kwambiri, ntchito zotentha kwambiri zimafunikira kulimbikitsa kwamphamvu kwa zida kuti zisawonongeke za intergranular pakutentha kocheperako.

Kutentha kwakukulu kwa okosijeni kukana
Zitsulo zosapanga dzimbiri zimakhala ndi kutentha kwambiri kwa okosijeni kukana, koma kuchuluka kwa okosijeni kumakhudzidwa ndi zinthu zachilengedwe monga malo owonekera komanso mawonekedwe azinthu.

Thupi katundu
Chiwerengero chonse cha kutentha kwachitsulo chimadalira zinthu zina, kuphatikizapo kutentha kwazitsulo. Nthawi zambiri, filimuyi kutentha kutaya koyenera, sikelo ndi zitsulo pamwamba chikhalidwe. Chitsulo chosapanga dzimbiri chimapangitsa kuti pamwamba pakhale paukhondo komanso mwaudongo, motero kutentha kwake kumakhala bwino kuposa zitsulo zina zokhala ndi matenthedwe apamwamba kwambiri. Liaocheng Suntory Stainless Steel imapereka miyezo yaukadaulo yama mbale zitsulo zosapanga dzimbiri. Ma mbale achitsulo osapanga dzimbiri amphamvu kwambiri okana dzimbiri, kupindika kopindika komanso kulimba kwa malo owotcherera, komanso kupondaponda kwabwino kwambiri pazigawo zowotcherera. Makamaka, ili ndi C: 0.02% kapena kuchepera, N: 0.02% kapena kuchepera, Cr: 11% kapena kupitilira apo ndi zosakwana 17%, komanso zofunikira za Si, Mn, P, S, Al, Ni, ndipo zimakwaniritsa 12 ≤ Cr Mo 1.5Si ≤ 17, 1 ≤ Ni 30 (CN) 0.5 (Mn Cu) ≤ 4, Cr 0.5 (Ni Cu) 3.3Mo ≥ 16.0, 0.006 ≤ CN ≤ 0.050 chitsulo chosasunthika ~ 50 ≤ 0.030 chitsulo chosasunthika ~ 030 , ndiyeno ikuchitika pa 1 ° C / s The pamwamba kutentha mankhwala kwa kuzirala mlingo kuzirala. Chifukwa chake, ikhoza kukhala kapangidwe kamene kamakhala ndi martensite yokhala ndi gawo la 12% kapena kupitilira apo, mphamvu yayikulu ya 730 MPa kapena kupitilira apo, kukana dzimbiri, kugwedezeka kwamphamvu, ndi chitsulo chosapanga dzimbiri champhamvu champhamvu kwambiri m'malo okhudzidwa ndi kutentha kwa weld. kulimba. Pogwiritsa ntchito Mo, B, ndi zina zotero, makina osindikizira a gawo lowotcherera amatha kusintha modabwitsa.

Lawi la oxygen kuphatikiza gasi silingadule chitsulo chosapanga dzimbiri chifukwa chitsulo chosapanga dzimbiri sichimathiridwa okosijeni mosavuta.
