Zinthu zamtundu wastructural chubu

Zinthu zambiri zosinthika zimayimira mawonekedwe akukokoloka kwapakatikati, zomwe ndi mankhwala opangira mankhwala ndi ndende yawo, mlengalenga, kutentha, nthawi, ngati simukumvetsetsa bwino za sing'angayo, kugwiritsa ntchito zida, kusankha kwazinthu kumakhala kovuta.Komabe, malangizo otsatirawa angagwiritsidwe ntchito posankha:

304 pakugwiritsa ntchito zinthu zonse.Mu nyumba akhoza kupirira dzimbiri ambiri, akhoza kupirira processing chakudya etching sing'anga (wokhala asidi moyikirapo koma kutentha ndi kolorayidi okhutira zingaoneke kukokoloka), mankhwala organic, utoto, ndi kudutsa zosiyanasiyana inorganic mankhwala akhoza kukana.

304L (otsika mpweya) ndi kukana zabwino asidi nitric, ndi cholimba sing'anga kutentha ndi ndende ya asidi sulfuric, ntchito ngati madzi mu thanki mpweya, ntchito zipangizo cryogenic (304N), ena onse ogula chipangizo chamagetsi, zipangizo khitchini, zida zachipatala, zida zoyendera, zida zogwiritsira ntchito madzi.

316 ili ndi nickel yoposa 304, ndipo ili ndi 2%─3% molybdenum, kukana dzimbiri kuposa mtundu wa 304, amakondera potengera kukokoloka kwapadera komwe kumachitika chifukwa cha chloride media.316 yakhala ikugwiritsidwa ntchito ngati makina opangira sulphite zamkati, chifukwa ndi olimba sulphate pawiri.Kuphatikiza apo, kugwiritsidwa ntchito kwake kwakulitsidwa kuti agwiritse ntchito mankhwala ambiri mumakampani opanga zinthu.

317 munali 3% -4% molybdenum (mkulu mlingo mu mndandanda nawonso analandira), ndipo lili oposa 316 mitundu ya chromium, ali ndi kukana apamwamba pitting dzimbiri ndi mng'anjo dzimbiri ntchito.

430 yotsika kuposa 304 alloy content, imagwiritsidwa ntchito m'malo otentha okongoletsedwa ndi ntchito zopukutidwa kwambiri, itha kugwiritsidwanso ntchito nitric acid ndi zida zopangira chakudya.

410 imagwiritsa ntchito zitsulo zosapanga dzimbiri katatu pazitsulo zotsika kwambiri, mumafunika mphamvu ndi kukana dzimbiri ndi zigawo zazikulu zonyamula katundu zomwe zimagwiritsidwa ntchito, monga zidutswa zolimba.410 m'malo ofunda, madzi, gasi ndi zinthu zamakina pawailesi yakanema ambiri kukana dzimbiri zolimbitsa thupi.

2205 kuposa 304 ndi 316 apamwamba, chifukwa kapangidwe ka chitoliro chake cha chloride stress corrosion corrosion cracking ali ndi mphamvu yayikulu yokana.
