Re: [MW:28368] evaluating of micro structure

Dear Ali,

Can you be more specific about the Material grade you are looking for? If we consider a case of P4 material like WP11, the heat treatment required is Normalised and Tempered condition. Hence the MTC shall mention this requirement and no further evaluation is required for micro structure examination.

Hope it answered your question.

Thanks and Regards,

Vino Varghese

Dear All.

Does anybody know how it is possible to evaluate the bainite or martensite of the base metal is tempered or not?

I want to know the method , frequency of testing, acceptance( such as figures) and any other issues that can say with confidently we have tempered micro structure or not?

as you know this is more crucial in sour service and is a requirement in our specification but doesn't mention detail of it.

Regards.
