Diferans prensipal la antAISI 316 (1.4401) asye purak AISI 316L (1.4404) asye pur se kontni an kabòn. "L" la vle di pou kontni "ba kabòn". Akòz kontni an pi ba kabòn, AISI 316L (1.4404) Nerjaveèi asye gen yon risk redwi nan sansibilizasyon (grenn limit limit carbure presipitasyon), men an menm tan an pèdi kèk fòs. AISI 316LN (1.4406) se asye pur alye ak nitwojèn pou konpanse pou pèt la fòs.
