Bayani: AF2209-15 wani lantarki ne mai ƙarancin sinadarin carbon nitrogen mai ɗauke da duplex na bakin ƙarfe mai ƙarancin sinadarin hydrogen. Yi amfani da DCEP (mai kyau ga lantarki kai tsaye). Aikin aiki yana da kyau. Domin yana ɗauke da molybdenum da nitrogen, kuma sinadarin carbon yana da ƙarancin sinadarin, ƙarfen da aka ajiye yana da kyakkyawan juriya ga tsagewa da kuma juriya ga tsagewa, musamman juriya ga tsagewa.
Aikace-aikace: Ana amfani da shi galibi don walda irin wannan nau'in kayan ƙarfe marasa ƙarancin carbon a masana'antar mai da na hydraulic. Kamar walda na ƙarfe mai duplex na 022Cr22Ni5Mo3N.
