Sida daawaha 316, kiimiko ee birta kaarboon-yar ee kaarboon-yar ayaa ka kooban chromium, nikkel, iyo molybdenum.Daawaha austenitic ee ka tirsan taxanaha 300, 317L Tubooyinka aan birta lahayn ee aan birta lahayn ayaa loo arkaa inay wax ka beddeleen fasalka 316. Waxa ku jira molybdenum ee kimistarigan alloy-ga ayaa ka sarreeya 3%.Daawaynta darajada molybdenum ee wax laga beddelay waxay leedahay sifooyin dhowr ah oo muhiim ah.Tusaale ahaan, WERKSTOFF NR.1.4438 Tube Heat Exchanger Tube waxay muujinaysaa iska caabin weyn oo ku wajahan godadka iyo daxalka dillaaca marka loo eego alloy 316.
