304/304L (UNS S30400/S30403) ndi chitsulo chosapanga dzimbiri chomwe chimagwiritsidwa ntchito kwambiri "18-8" chromium-nickel austenitic.Ndi aloyi yachuma komanso yosunthika yomwe imagwira ntchito zosiyanasiyana.

Kufotokozera Kwachidule:

Ndizofala kuti 304L ikhale yovomerezeka ngati 304 ndi 304L.Kutsika kwa carbon chemistry ya 304L pamodzi ndi kuwonjezera kwa nayitrogeni kumathandizira 304L kukumana ndi makina a 304.

304/304L imalimbana ndi dzimbiri mumlengalenga, komanso, oxidizing ndi kuchepetsa chilengedwe.The aloyi ali kwambiri kukana dzimbiri intergranular mu chikhalidwe monga welded.304/304L ili ndi mphamvu zabwino komanso zolimba pa kutentha kwa cryogenic.

304/304L si maginito mu annealed chikhalidwe, koma amatha kukhala maginito pang'ono chifukwa cha kuzizira ntchito kapena kuwotcherera.Itha kuwotcherera mosavuta ndikukonzedwa ndi njira zopangira masitolo.

Kukaniza kwa Corrosion

304/304L imalimbana bwino ndi dzimbiri mumlengalenga, zakudya ndi zakumwa komanso mankhwala ambiri okhala ndi organic ndi ma inorganic okhala ndi oxidizing pang'ono mpaka kuchepetsa pang'ono.Kuchuluka kwa chromium mu aloyi kumapereka kukana kwa oxidizing njira monga nitric acid mpaka 55% kulemera ndi mpaka 176 ° F (80 ° C).
304/304L imakanizanso ma organic acids amphamvu kwambiri monga acetic.Nickel yomwe ilipo mu aloyiyi imapereka kukana kumachepetsa pang'onopang'ono mayankho monga phosphoric acid yoyera, mosasamala kanthu za kuchuluka kwake, muzitsulo zoziziritsa kukhosi komanso mpaka 10% yothira madzi otentha.Aloyiyo imatha kugwiranso ntchito bwino munjira zopanda ma chloride kapena Aloyi 304/304L sichita bwino m'malo ochepetsa kwambiri monga omwe ali ndi ma chlorides ndi sulfuric acid.
304/304L imagwira ntchito bwino m'madzi abwino okhala ndi ma chloride otsika (osakwana 100ppm).Pamilingo ya kloridi yokwera kwambiri, kalasiyo imatha kuwononga dzimbiri komanso kuphulika.Kuti mugwire bwino ntchito pamikhalidwe yovuta kwambiri iyi, zomwe zili ndi molybdenum zimafunika 316/316L.304/304L siyovomerezedwa kuti igwiritsidwe ntchito m'malo am'madzi.
Nthawi zambiri, kukana kwa dzimbiri kwa 304, 304L ndi 304H kudzakhala kofanana m'malo ambiri owononga.Komabe, m'malo omwe ali ndi dzimbiri mokwanira kuti awononge ma welds ndi madera omwe amakhudzidwa ndi kutentha kwa 304L ayenera kugwiritsidwa ntchito chifukwa chokhala ndi mpweya wochepa.

Kugwiritsa ntchito

304L Stainless Steel imagwiritsidwa ntchito pazinthu zosiyanasiyana zapakhomo ndi zamalonda, kuphatikiza:
▪ Zida zopangira chakudya, makamaka popangira moŵa, popanga mkaka, ndi kupanga vinyo
▪ Mabenchi akukhichini, masinki, mbiya, zida, ndi zida
▪ Zomangamanga ndi kuumba
▪ Kugwiritsa ntchito magalimoto ndi ndege
▪ Zida zomangira m’nyumba zazikulu
▪ Mitsuko ya mankhwala, kuphatikizapo zonyamulira
▪ Zida zotenthetsera
▪ Mtedza, mabawuti, zomangira, ndi zomangira zina za m’nyanja
▪ Makampani opanga utoto
▪ Zotchingira zoluka kapena zowotcherera zopangira migodi, kukumba miyala ndi kusefera madzi
