How to detect the solution treatment effect of S31603 stainless steel fittings?

Comparison of hardness before and after metallographic inspection and solution treatment for the fittings. The latter is simpler while the former is a bit more complex. There is also the simplest and most practical method that anyone can use without any training.

The simplest way is to use magnetic testing; if the S31603 meets the requirements for solution treatment, try it with a magnet – it will have almost no magnetism

It can be used as a reference. It’s just a lack of data to support it.

Do we still need data? The purpose of solution treatment is to restore austenite; if a magnet cannot attract it, it means there is almost no ferrite left. I would say this method is more accurate than the metallographic method
