Effect of urea ammonium nitrogen fertilizer on corrosion of different metals
Author(s): Prem K Sundaram, Indra Mani and Roaf A Parray
Abstract: Corrosion rate helps in understanding the vulnerability of metals to corrosion. An experiment was conducted to investigate the effect of liquid fertilizer (Urea Ammonium Nitrate) with different dissolution ratio with water on the corrosion rate of different metals. Three dissolution ratios of UAN and water viz. 1:0, 1: 5 and 1:10 were used for corrosion treatment. Metal coupons of three metallurgies-stainless steel (SS), mild steel (C1010 grade) and mild steel (commercial) were used for the study. The corrosion coupons were fully suspended in the fertilizer solutions inside the airtight glass jars. Metal corrosion coupons started corroding within 24 hours. The metal coupons were weighed after 281, 681 and 1025 h. The average corrosion rates were 0.55 mm per year and 0.311 mmy-1 for MS (Commercial) and MS C1010, respectively.
