Can a 14mm thick plate be used as a substitute for one that is 13mm thick?
Thread Content
Our company has a batch of nuclear power equipment; for the web plates beneath the tanks, we are unable to find 13mm thick 304 stainless steel sheets, so we are using 14mm thick 304 stainless steel sheets as a substitute. Is it necessary to go through any additional procedures? Please advise. Thank you!
Using a larger size in place of a smaller one should work as a substitute, but it requires approval from the design team and the relevant departments at the client’s side. It’s best to consult with the design firm and explain the situation clearly to the client.:)
Since it is a web under the tank, as long as it does not affect assembly, it can be used as a substitute directly. If your company’s rules regarding material substitution require procedures to be followed for any type of substitution, then follow the established procedures.

The material remains the same, so substitution is generally not a problem, but the usual procedures must still be followed, as it is necessary to consider whether it will affect the dimensions of other parts
It’s pretty strange; it’s the first time I’ve seen anyone design one that’s 13 layers thick.
Stainless steel is expensive; try to save where you can. Even 1mm thick still costs money
If it is not a primary stressed component, it can be resolved on its own; otherwise, a substitute can be used, but the procedures for obtaining such a substitute material must be followed
Using a thicker one in place of a thinner one should work, but formal substitution procedures must be followed.
The corresponding procedures must be followed as required, but I don’t understand why the design specifies a web thickness of 13 mm under the tank, instead of rounding it up to 14 mm Does the nuclear power industry often use such unusual materials without considering market conditions? :o
13mm is quite standard for stainless steel. Judging from the problem, it is a structural component; using 14mm should be fine.
