All rights reserved.AISI 316L is a type of stainless steel that is frequently used in various industries such as chemical industry, refining industry, marine industry, etc. AISI 316L known for its resistance to localized corrosion. But in the reality, pitting corrosion was found on AISI 316L in some applications. Several factors can cause pitting corrosion, such as temperature and chloride concentration. Therefore its conducted a study on the effect of temperature and chloride concentration on pitting corrosion behavior of AISI 316L. Based on this reason, the immersion method was done by varying the temperature 15oC, 27oC, 40oC and 60oC and varying chloride concentration of 1.85 M, 2.39 M and 2.87 M. Immersion method used solution which is contain of ferric chloride (FeCl3.6H2O), HCl, and aqua dm. Immersion method conducted for 1 day (24 hours) with stirring speed 250 rpm. From this experiment, it was found cross section of pit is wide and shallow. Then it was found temperature and chloride concentration factors influence on the corrosion behavior of AISI 316L. The increase in temperature will increase the damage of AISI 316L, which is increasing number, diameter, and the maximum depth of the pit. Increased chloride concentrations also increase the damage of AISI 316L, which is increase in number and maximum pit depth. In addition a range of values of critical pitting temperature is decreased with increasing concentrations of chloride. The conclusion of this research is the parameters of temperature and chloride concentration will increase the damage of pitting corrosion of AISI 316L. Moreover, it can be proved that the increase in chloride ion concentration will decrease the value of the critical pitting temperature of AISI 316L.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Aisi 316l,Chloride concentrations,Chloride ion concentration,Corrosion behavior,Critical pitting temperatures,Effect of temperature,Immersion method,Refining industry[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]AISI 316L,Chloride concentration,Immersion method,Pitting corrosion,Temperature[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
