The material of the high-pressure steam pipeline is substandard

Thread Content

After welding the high-pressure steam pipes made of 12Cr1Mnv heat-resistant steel in our factory, it was found that one of the pipes had not undergone heat treatment upon arrival; however, it is impossible to determine which one it is. What is a simple method to identify it? Measure hardness? Is the difference big? Looking forward to your advice!

Metallographic testing requires sampling; the pipes have all been installed. No, we can only take samples.

It should be able to measure hardness, and it’s simple and practical.
