MitunduChithunzi cha 310SndiChithunzi cha 314SSndi zitsulo zosapanga dzimbiri za austenitic zopangidwira kuti zizigwira ntchito pa kutentha kokwera.Zomwe zili m'kati mwa Cr ndi Ni zimathandizira kuti alloy iyi isakane makutidwe ndi okosijeni muutumiki wopitilira kutentha mpaka 2200 ° F pokhapokha ngati mpweya wochepetsera wa sulfure palibe.Muutumiki wapakatikati, 310S SS ingagwiritsidwe ntchito pa kutentha mpaka 1900 ° F chifukwa imakana kukweza ndipo imakhala ndi coefficient yocheperako yakukulitsa.Kuchulukitsa kwa silicon mu 314 SS kumapangitsanso kukana kwa okosijeni pa kutentha kwakukulu.Carburizing mpweya ukhoza kuchepetsa moyo wonse kutengera momwe zinthu zilili.Komabe, magiredi awa ali ndi kukana kwakukulu poyerekeza ndi magiredi otsika a chromium-nickel.
Magirediwa amagwiritsidwa ntchito pakukana kwawo kutentha kwambiri kwa okosijeni pazogwiritsa ntchito monga mbali za ng'anjo, malamba otumizira ng'anjo, zotsekera zosungira, ndi zina zambiri.
ZOCHITIKA ZILIPO
Onani tsamba lazogulitsa kuti muwone kukula, kulolerana, zomaliza zomwe zilipo ndi zina zambiri.
