304L Wopanga chitoliro mosalekeza
Kufotokozera
Machubu athunthu a Stainless Steel 304/304l / 304H amapangidwa pogwiritsa ntchito mtundu wa alloy womwe umawonjezera mphamvu zabwino kwambiri ndi zinthu zonse zofunika.Zimapangidwanso poganizira za makhalidwe abwino a zinthu monga ASTM, ANSI, ASME, etc. SS 304 ndi chitsulo chosapanga dzimbiri cha austenitic chokhala ndi 20% ya chromium ndi 8% ya nickel.Ndi aloyi yopanda maginito yomwe imatha kupangidwa ndi maginito ikamagwira ntchito yozizira.Aloyiyo imakhala ndi kukana kwa dzimbiri kwabwino kwambiri, kulimba kwamphamvu kwambiri, komanso kukana bwino kwa pitting.
SS 304L ili ndi mpweya wochepa womwe umapereka katundu wabwino ku Machubu.Amakhalanso ndi mphamvu zambiri, katundu wabwino wamfupi, komanso kukana kwa SCC kwabwino kwambiri.Alloy iyi ndi yothandiza pazochitika monga-weld chifukwa imatha kulekerera kutentha kwambiri.
304 ndi mtundu wa chitsulo chosapanga dzimbiri, chomwe chimagwiritsidwa ntchito kwambiri popanga zida ndi magawo omwe amafunikira katundu wabwino wokwanira (kukana kwa dzimbiri ndi mawonekedwe). ku China 0Cr19Ni9 (0Cr18Ni9) zitsulo zosapanga dzimbiri.304 ili ndi 19% chromium ndi 9% nickel.304 ndi zitsulo zosapanga dzimbiri zomwe zimagwiritsidwa ntchito kwambiri ndi zitsulo zosapanga dzimbiri komanso zitsulo zosagwira kutentha.Zogwiritsidwa ntchito popanga chakudya, zida za mankhwala a Xitong, mphamvu za nyukiliya, ndi zina zotero.
Kugwiritsa ntchito
Chitoliro chamadzi cha 304 chosapanga dzimbiri ndi chitoliro chabwino kwambiri chamadzi akumwa chakumwa.304 zinthu zoonda zamakhoma zosapanga dzimbiri zosapanga dzimbiri, zokhala ndi chitoliro chamadzi otsika, zimatha kupulumutsa mawonekedwe amadzi amtengo wapatali. ndi mipope ya madzi ozizira. Zaka zana zapitazi pamene chitoliro cha madzi kutayikira mu 1980 pafupifupi 17 peresenti, pambuyo kusintha kwa 304 zitsulo zosapanga dzimbiri chitoliro madzi chitoliro kutayikira mlingo 7 peresenti. The madzi dongosolo kuonongeka pa chivomezi, pamene 304 zosapanga dzimbiri mipope. Kuphatikiza apo, poyerekeza ndi chitoliro chamadzi amkuwa, 304 chitsulo chosapanga dzimbiri madzi chitoliro permeability ndi chabwino, pankhani ya kuchuluka kwa otaya si corrod. apamwamba.
304 chubu chachitsulo chosapanga dzimbiri chomwe chimagwiritsidwa ntchito kumunda wokongoletsera, chubu chachitsulo chosapanga dzimbiri cha 304 chifukwa champhamvu kwambiri, kutha kwa khoma lamkati, kukana kuvala bwino ndi zabwino zina, chifukwa chake chimagwiritsidwa ntchito kwambiri pantchito zokongoletsa, monga nyumba yathu wamba masitepe achitsulo chosapanga dzimbiri. guardrail, amapangidwa ndi 304 zitsulo zosapanga dzimbiri kukongoletsa ulamuliro.Ambiri 304 zosapanga dzimbiri zitoliro opanga anapanganso zambiri 304 zitsulo zosapanga dzimbiri kukongoletsa chitoliro kamangidwe, chitsanzo, chitsanzo, kwa ogula ambiri kusankha.Izi zikhoza kuoneka kuti 304 zosapanga dzimbiri chubu m'makampani okongoletsera ndi digiri yomwe aliyense amakonda.
