I had a flame pad like this:

but for domestic use; those round you can find in general stores, made from stainless steel for kitchen stove.
I was very disappointed because it corroded and broke into pieces, eaten by stove's flame.
Conclusion -not all stainless steels resist high temperature oxidation, they are not refractory and even at normal temp their resistance is average, limited to normal dishware conditions; it is what also metal casting enthusiast say about ad-hoc stainless steel crucibles, although the corrosion agents here are multiple.
In what concerns brazing, Google for Oxigen concentrator /welding. It is an interesting mean to increase temperature and power density (welding-source of oxygen- or brazing); sometimes a bit too much - I have tried it, to inject a stream of oxygen in burner's admission... The speed of flame is much faster/ commercial burners are already built to work to their limit/ a.s.o.
For welding, power is limited by oxygen flow available but the method is much more tested and you can find tutorials. Works for small jobs.
