Dear All
We have a new designed 16" valve made in Gr 6A. During the heat treatment it was crecked. Do anyone have a typical chart for Superduplex heat treatment?
I assume we have to hold around 300-400 deg C for first step and haet up to 1100-1200 and holding there for sufficient time than water quechend.
Our chart is goes up 1150 deg C straitaway raffle 80 deg C / hours.
Thank you
Regards
