Is this tempered martensite?

Dear all,
can anyone advise me is the microstructure in the picture that I had attached tempered martensite? Thanks!

There is not enough information to provide a recommendation on the microstructure. Appearances can be deceiving.
What is the material?
What was the heat treatment?
PS; I have noticed you are posting with increased frequency questions that a materials engineer/consultant should be able to answer on their own. My only advice is to be careful with your questions because we are not here to provide free consulting advice. Also, as with any free advice, it is worth what you paid for it!

TemperedMartensite, I had etched with 2% nital. This material was made to be a pipe and was bent by heating it to 1050 Deg C and water quenched. No normalizing was done afterwards. I was quite surprised not to see fully tempered martensite structure as the wall thickness was 20mm only.
CoryPad, actually I concluded that the microstructure was a mix of tempered martensite with scattered ferrite. Do correct me if I am wrong. Thanks!
