Wamba chitsulo chosapanga dzimbirizitsanzo
Ambiri ntchito zosapanga dzimbiri zitsanzo zambiri ntchito manambala zizindikiro, pali 200 mndandanda, 300 mndandanda, 400 mndandanda, iwo ndi United States of America woimira, monga 201, 202, 302, 303, 304, 316, 410, 420, 430, etc., mitundu yachitsulo chosapanga dzimbiri yaku China imagwiritsidwa ntchito muzizindikiro zazinthu kuphatikiza manambala, monga 1Cr18Ni9, 0Cr18Ni9, 0Cr17, 3Cr13, 1Cr17Mn6Ni5N, ndi zina zambiri, ndipo manambala amawonetsa zomwe zili. 00Cr18Ni9, 1Cr17, 3Cr13, 1Cr17Mn6Ni5N ndi zina zotero, nambala imasonyeza zomwe zili zogwirizana.
200 mndandanda: chromium-nickel-manganese austenitic chitsulo chosapanga dzimbiri
300 mndandanda: chromium-nickel austenitic chitsulo chosapanga dzimbiri
301: Ductility yabwino, yogwiritsidwa ntchito pazinthu zopangidwa. Ikhozanso kuumitsidwa ndi liwiro la makina. Weldability wabwino. Kuvala kukana ndi kutopa mphamvu kuli bwino kuposa 304 zitsulo zosapanga dzimbiri.
302: kukana dzimbiri ndi 304, chifukwa chokhala ndi mpweya wambiri komanso mphamvu yabwinoko.
302B: Ndi mtundu wachitsulo chosapanga dzimbiri chokhala ndi silicon wochuluka, womwe umalimbana kwambiri ndi makutidwe ndi okosijeni otentha kwambiri.
Paphata pa Chichewa 303: Powonjezera sulfure ndi phosphorous pang’ono kuti zitheke kutheka.
303Se: Amagwiritsidwanso ntchito popanga zida zamakina zomwe zimafuna mutu wotentha, chifukwa chitsulo chosapanga dzimbirichi chimakhala ndi ntchito yabwino yotentha pansi pazimenezi.
304: 18/8 chitsulo chosapanga dzimbiri. Mtengo wa 0Cr18Ni9. 309: kukana kutentha kwabwino kuposa 304.
304L: Chosiyana cha 304 chitsulo chosapanga dzimbiri chokhala ndi mpweya wocheperako, wogwiritsidwa ntchito pomwe kuwotcherera kumafunika. Mpweya wochepa wa carbon umachepetsa mvula ya carbides m'madera omwe amakhudzidwa ndi kutentha pafupi ndi weld, zomwe zingayambitse intergranular corrosion (kukokoloka kwa weld) kwa chitsulo chosapanga dzimbiri m'madera ena.
304N: Chitsulo chosapanga dzimbiri chokhala ndi nayitrogeni, chomwe chimawonjezeredwa kuti chiwonjezere mphamvu yachitsulo.
305 ndi 384: Zokhala ndi nickel wambiri, zimakhala ndi ntchito yochepa yochepetsera ntchito ndipo ndizoyenera kugwiritsa ntchito mitundu yosiyanasiyana yomwe imafuna kuzizira kwambiri.
308: Amagwiritsidwa ntchito popanga ndodo zowotcherera.
309, 310, 314 ndi 330: za nickel ndi chromium ndizokwera kwambiri, kuti zipititse patsogolo kukana kwa okosijeni kwachitsulo pakutentha kwambiri komanso kulimba kwamphamvu. Ngakhale 30S5 ndi 310S ndi mitundu ya 309 ndi 310 zitsulo zosapanga dzimbiri, kusiyana kwake ndikuti mpweya wa carbon ndi wotsika, kotero kuti ma carbides omwe amawotchedwa pafupi ndi weld amachepetsedwa. 330 chitsulo chosapanga dzimbiri chimakhala ndi kukana kwakukulu kwa carburization komanso kukana kugwedezeka kwa kutentha.
316 ndi 317: ali ndi aluminiyamu, motero amakhala ndi kukana kwabwinoko pakuyika dzimbiri m'malo am'madzi ndi mafakitale am'madzi kuposa 304 zitsulo zosapanga dzimbiri. Pakati pawo, lembani 316 chitsulo chosapanga dzimbirindi mitundu yosiyanasiyana monga chitsulo chosapanga dzimbiri chochepa cha carbon 316L, nayitrogeni wokhala ndi chitsulo chosapanga dzimbiri cha 316N, komanso sulfure yapamwamba yachitsulo chosapanga dzimbiri cha 316F.
321, 347 ndi 348: ndi titaniyamu, niobium kuphatikiza tantalum, niobium okhazikika zitsulo zosapanga dzimbiri, zoyenera kugwiritsidwa ntchito pa kutentha kwambiri mu zigawo welded. 348 ndi mtundu wa chitsulo chosapanga dzimbiri choyenera makampani opanga mphamvu za nyukiliya, tantalum ndi kuchuluka kwa kubowola pamodzi ndi kuletsa kwina.
400 mndandanda: ferritic ndi martensitic zitsulo zosapanga dzimbiri
408: Kukana kutentha kwabwino, kukana kwa dzimbiri, 11% Cr, 8% Ni.
409: mtundu wotsika mtengo kwambiri (wa Britain ndi America), womwe nthawi zambiri umagwiritsidwa ntchito ngati mapaipi otulutsa magalimoto, ndi chitsulo chosapanga dzimbiri cha ferritic (chromium steel)
410: martensitic (chitsulo champhamvu kwambiri cha chromium), kukana bwino kuvala, kukana kwa dzimbiri. 416: sulfure yowonjezera imapangitsa kuti zinthu zitheke.
420: "Chida chodula" chitsulo cha martensitic, chofanana ndi Brinell high-chromium steel, chitsulo choyambirira chosapanga dzimbiri. Amagwiritsidwanso ntchito ngati mipeni yopangira opaleshoni ndipo imatha kukhala yowala kwambiri.
430: Ferritic chitsulo chosapanga dzimbiri, zokongoletsera, mwachitsanzo pazowonjezera zamagalimoto. Mawonekedwe abwino, koma kukana kutentha ndi kukana kwa dzimbiri ndizotsika.
440: chitsulo cham'mphepete champhamvu kwambiri, chokhala ndi mpweya wokwera pang'ono, pambuyo pa chithandizo choyenera cha kutentha chikhoza kupeza mphamvu zokolola zambiri, kuuma kumatha kufika ku 58HRC, kumakhala chitsulo chosapanga dzimbiri cholimba kwambiri. Chitsanzo chodziwika bwino cha ntchito ndi "lumo". Pali mitundu itatu yomwe imagwiritsidwa ntchito: 440A, 440B, 440C, ndi 440F (mtundu wosavuta ku makina).
500 Series: Chitsulo chachitsulo cha chromium chosagwira kutentha
600 Series: Martensitic mpweya-umitsa zitsulo zosapanga dzimbiri
630: Chitsulo chosapanga dzimbiri chomwe chimagwiritsidwa ntchito kwambiri ndi mvula, chomwe chimatchedwa 17-4; 17% Kr, 4% Ni.
