Dear #EdStainless

Heated to 1175° C, soaked for 2 Hrs, Water Quenched. Stabilizing to 970° C, soaked for 4 Hrs, Forced air cooled.

Results are not achieved. Please provide your valuable input.

As per SA-494 Clause 6 Note-1, heat treatment at higher temperature may be required.

Dear Gautam

It is 2100° F in standard

 

[goutam_freelance]

It is minimum, can be increased.

 

[A M Contractor]

Ok. what do you suggest?

 

[goutam_freelance]

I am not a metallurgist. Please talk to your metallurgist whether the temperature can be increased.

My personal suggestion is;
Homogenize at 2200-2250F for 4-5 hours, cool to RT, then anneal at 2150-2175 and water quench.
Check the micro, and then stabilize, and check micro again.

I am in process. I will update as soon as I get results. Thanks
