Cymwysiadau a manteision 321 o bibell ddur di-staen
Mae 321 o bibellau dur di-staen, oherwydd eu triniaeth sefydlogi titaniwm, yn atal cronni carbid ac felly mae ganddynt wrthwynebiad rhagorol i gyrydiad rhyng-gronynnog. Felly, maent yn cael eu ffafrio'n fawr mewn amgylcheddau tymheredd uchel a chyrydol ac maent yn ddelfrydol ar gyfer offer gwacáu awyrofod, prosesu cemegol ac offer bwyd. Maent hefyd yn cynnal weldadwyedd, cryfder a pherfformiad rhagorol ar dymheredd hyd at 900 gradd (1650 gradd F).
Beth yw'r defnydd o 321 o ddur di-staen?
Mae'n ddelfrydol ar gyfer gweithgynhyrchu cyfnewidwyr gwres, llestri pwysau a thanciau storio. Offer thermol: Mae boeleri, cyfnewidwyr gwres, a chydrannau ffwrnais yn aml yn cael eu gwneud o 321 o ddur di-staen oherwydd ei wrthwynebiad gwres rhagorol a'i wrthwynebiad ocsideiddio. Fe'i darganfyddir yn gyffredin hefyd mewn offer trin gwres diwydiannol.
