Greg...
You'll have a quicker time reaming out the holes and re-tapping them to suit.
I am puzzled. If the bodies are common steel -- how can SS provide advantage?

American engineers use 'threads per inch' as a metric.
European engineers adopted 'millimeters per thread' as a metric.
This is why Hotline's math was necessary.
It's also why the ordinary Joe is stumped when looking at metric fasteners.
At first blush, it's not obvious which thread is coarse or fine.
M5x0.8mm is going to be 'finer' than M5x1.0mm.
Most of the metric threads on sale in America are destined for the automobile -- hence FINE threads.
In our trade, most of the threads are coarse:
10 x 24 versus 10 x 32
1/4 x 20 versus 1/4 x 28
5/16 x 18 versus 5/16 x 24
3/8 x 16 versus 3/8 x 24
So I'm not surprised that M5x1.0mm is scarce.
