Influence of the stainless steel 321 (X18Н10) structure on pitting corrosion in low-mineralized water. Inhibiting effect of sulfate and hydrocarbonate ions

This paper describes the pitting corrosion monitoring of ferritic and austenitic stainless steel under a simulated acidic condition of marine appications. The monitoring deals with the corrosion weight loss and metallurgical investigation. The results indicated that the stainless steel with passive film shows the good corroison resistance to the simulated corrosive environment for the all test periods. In contrast, the stainless steel without passive film cannot provide the inhibiting effect for the whole test periods. After the 24 hr. of testing , both of the stainless steel are locally attacked. Pitting corrosion was observed on the surface of both stainless steels. In small pits, the self-accelerating corrosion can occur. Therefore, the longer immersion time attributes to the higher corrosion rate of both stainless steel in a simulated acidic conditions.

Pitting Corrosion Resistance

Abstract Nirosta 4429 is a low-carbon, high-nitrogen version of type 316 stainless steel. The low carbon imparts intergranular corrosion resistance while the nitrogen imparts both higher strength and some increased pitting corrosion resistance. It is recommended for use as welded parts that need not or cannot be annealed after welding. This datasheet provides information on composition, physical properties, elasticity, and tensile properties. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, and joining. Filing Code: SS-787. Producer or source: ThyssenKrupp Nirosta.
