The 18-8 alloys are not recommended for exposure to marine environments which have much higher levels of chloride. The resistance of the stabilized Alloys 321 to pitting and crevice corrosion in the presence of chloride ion is similar to that of Alloy 304 or 304L stainless steels because of similar chromium content.
For this reason, stainless steels are being used in increasingly corrosive brine environments. The risk for corrosion in brines is associated with the chloride content, temperature, pH and oxygen level. This paper aims to explore the corrosion resistance of some stainless steels in highly concentrated sodium chloride solutions. Effect of sodium chloride on corrosion of mild steel in CO Mar 30, 2011 · Chloride is well known to play a crucial role in steel corrosion, but its effect depends on whether the aqueous system is deaerated (oxygen-free), oxygen-aerated, or deaerated but CO 2-bearing. In deaerated acidic solutions, chloride accelerates the anodic kinetics of iron dissolution via a catalytic mechanism . In deaerated neutral and alkaline solutions, a corrosion scale is usually formed. Resistance to Corrosion - Stainless Steel Tube Stainless Alloy 304 stainless steel is considered to resist pitting and crevice corrosion in waters containing up to about 100 ppm chloride. The Mo-bearing Alloy 316 and Alloy 317L on the other hand will handle waters with up to about 2000 and 5000 ppm chloride, respectively.
ASTM B895 comprises two methods for evaluating the ability of sintered PM stainless steel parts/specimens to resist corrosion when immersed in an aqueous solution of sodium chloride (5% NaCl). In Method 1, the test pieces are examined periodically and the time to the first appearance of rust is used to indicate the end point.

Abstract:Austenitic stainless steel 316L has been widely used in marine environment which containing sodium chloride solution (NaCl). In order to provide matching properties with parent metal, filler metal SMA 316L is commonly produced with slightly over alloyed composition. This work investigated the corrosion behavior of base metal 316L and SMA 316L weld metal by using Electrochemical Impedance Spectroscopy (EIS) to evaluate the mechanism of corrosion Corrosion of Stainless Steel in Sodium Chloride Brine Mar 09, 2014 · The resistance to localized corrosion of stainless steels in 20,000,100,000 and 200,000 ppm Cl - sodium chloride solutions was investigated at 90°C. The effects of chloride content, oxygen content and solution pH were studied on test coupons with and without welds and on U-bend specimens.
