A234 WP11 Class 2 microstructure
A234 WP11 Class 2 microstructure
(OP)
Good morning to all,
We are manufacturing a red tee, the dimensions are OD 508x20.62WT and OD 457.2x19.05 WT.
The material is ASTM A234 WP11 Class 2
The heat treatment is normalize and temper, with air cooling, as per Code.
The heat treatment parameters are:
-normalization, soaking temperature 920 °C, soaking time 2 minutes/mm, rapid air cooling
-tempering, soaking temperature 650 °C, soaking time 2 minutes/mm, still air cooling
The microstructure obtained is the following:

Can anyone tell me if the microstructure is conforming, please?
Thank you,
