It should technically be cast steel not iron for a turbo manifold so it will have better results but in general. Preheat high nickel fill rod reheat and cool slowly. If the manifold has run for a significant time it can have more carbon in it leading to more brittleness also something to be careful about.

looks like the style HKS used on their early garrett single turbo kits like the T04E and S kits...it's a system of compression rings that seal ...probably common on diesel truck vehicles...seen pictures of the kits and not the most inspiring looking downpipe to turbine connections at a glance.

I thought turbo hotsides/turbine housings were made of cast iron?

Most production turbo housings and manifolds of recent manufacture are D5-S Ni-resist.

look up truck parts supply stores in your area....take the turbine to them and they should be able to get you the male flange and ring assembly...I did that with a garrett turbine housing off a truck application with a wider v band casting on it then the norm... they ordered the matching tube flange to weld on the downpipe and v-band for me...dirt cheap also

Maybe try and PM user "markus1981". I may be wrong but im pretty sure he recently installed an older HKS turbo with a similar looking flange, and asked the same question re "what flange is it"
He posted a pic in his build thread, link below, and at a glance, that looks to be the same flange as in your image;

I dont think he ever came back and updated what the flange was, but I do believe he got it sorted and installed in the end (with that flange) so it mite pay to flick him a message and see what he knows.
If you do figure out what flange that is, please do post it back here. Its obviously stumped quite a few knowledgeable people as you don't yet have a solid answer.
