Giredi 316 ndiye giredi yokhazikika yokhala ndi molybdenum, yachiwiri kufunikira mpaka 304 pakati pazitsulo zosapanga dzimbiri za austenitic.Molybdenum imapatsa mphamvu 316 yabwinoko yolimbana ndi dzimbiri kuposa Giredi 304, makamaka kukana kutsekereza ndi kuwonongeka kwa ming'alu m'malo a chloride.
Chitsulo chosapanga dzimbiri - Gulu 316L - Katundu, Kupanga ndi Kugwiritsa Ntchito (UNS S31603)
Giredi 316L, mtundu wa 316 wochepa wa kaboni ndipo sukhudzidwa ndi kukhudzidwa (grain boundary carbide precipitation).Chifukwa chake, amagwiritsidwa ntchito kwambiri pazinthu zowotcherera zolemera (zopitilira 6mm).Nthawi zambiri palibe kusiyana kwamitengo pakati pa 316 ndi 316L chitsulo chosapanga dzimbiri.
Mapangidwe a austenitic amapatsanso magirediwa kulimba kwambiri, ngakhale mpaka kutentha kwa cryogenic.
Poyerekeza ndi zitsulo zosapanga dzimbiri za chromium-nickel austenitic, 316L chitsulo chosapanga dzimbiri chimapereka chiwopsezo chambiri, kupsinjika mpaka kuphulika ndi kulimba kwamphamvu pakutentha kokwera.
Zofunika Kwambiri
Chitsulo chosapanga dzimbiri - Gulu 316L - Katundu, Kupanga ndi Kugwiritsa Ntchito (UNS S31603)
Zinthu izi zimatchulidwa pazinthu zopindika (mbale, pepala, ndi koyilo) mu ASTM A240/A240M.Zofanana koma osati zofananira zimatchulidwa pazinthu zina monga chitoliro ndi bar muzofunikira zawo.
