Relationship between chloride ion concentration and corrosion rate of 304 stainless steel
Thread Content
My friends, what is the linear relationship between chloride ion concentration and the corrosion rate of 304 stainless steel? What is the corrosion rate of 304 in a solution containing 30 ppm chloride ions?
The corrosion of stainless steel caused by chloride ions is generally not assessed in terms of rate; it mainly involves localized forms of corrosion such as stress corrosion. This diagram can serve as a reference for you
What I want to know is, under chloride conditions, how long does it take for the S30408 material to develop stress corrosion or other types of corrosion?
Just a quick question: which book does this picture come from?
For austenitic stainless steels, chloride stress corrosion cracking is the main concern; one can refer to the relevant provisions in API 581
Come and learn*. Understanding the corrosion rate does not solve the corrosion problem; isn’t it better to think about ways to address it?
