What is the hardness of Q345D steel pipes?

Thread Content

I purchased a batch of Q345D steel pipes. The warranty certificate does not specify the hardness value, and it’s not convenient to conduct tests. Do any experts know what the hardness value is? Thank you

Q345D steel pipes are suitable for low-temperature environments, and no specific requirements are generally imposed on their hardness. If required, consult the design institute for specific specifications.

You can ask a qualified testing agency to conduct the testing; Brinell hardness is easy to measure.
