Inconel625 reduces intergranular corrosion

This post was last edited by 277600633 on 2015-12-30 10:29. How can the intergranular corrosion resistance of Inconel625 be improved? What is the acceptable standard value for intergranular corrosion?
What is the allowable standard value for intergranular corrosion? Are you looking for the standard values for intergranular corrosion test results? The values vary depending on which intergranular corrosion test is being conducted.
Replace circular tubes with twisted heat exchange tubes
ASTM G28 Method A procedure
It seems there are no specific values specified in this standard. The contracts with our manufacturers generally require that, after corrosion occurs in the sensitized parts and the solution-treated parts, the ratio of the corrosion rate of the sensitized parts to that of the solution-treated parts be less than 1.5.
In the last experiment, the rate was 1.14 millimeters per year. I also learned from third parties that there are indeed no standard values; everything is determined based on the requirements specified by the manufacturer and the customer. So how can we reduce his corrosion rate? In terms of composition and heat treatment
I’m sorry, I don’t have a good answer for this either.
