Intsimbi ye-Super austenitic ASME SA213 · Umbhobho we-S31254.SMO254

Inkcazo emfutshane:

I-254 SMO (UNS S31254) yintsimbi engagqwali ye-austenitic ehambelana nezinye iintsimbi ezingagqwali ze-austenitic kwaye yenzelwe amanqanaba aphezulu e-chromium, i-molybdenum, kunye ne-nitrogen ukuze ikwazi ukumelana nokugqwala okuphezulu kunye nokuqhekeka kwemingxuma. Le ngxubevange ikakhulu yi-chromium–molydenum–nickel alloy ene-nitrogen ehlala iyinto eyongezelelweyo; ulwakhiwo oluqikelelweyo yi: Cr 20%–22%, Mo 6%–7%, Ni 18%–20%, kunye ne-nitrogen ekhulisa amandla ayo kunye nokuxhathisa ukugqwala, ngakumbi kwiindawo ezine-chloride ezifana namanzi olwandle, ezisebenza kumashishini ephepha, epulp, nakwiikhemikhali.
