<p>Agree. Anecdotally--I've only worked a bit with SS--I believe it
to be harder and more brittle than mild steel. A couple of cases:</p>
<p>- when trying to get a gas-tight and permanent seal at the
exhaust manifold to downpipe flange, I tried some SS studs from
Doug Reid. They seemed to snap off with less torque than the mild
steel ones, which I ended up using</p>
<p>- I was experimenting with safety wiring the set pins in my
gearbox, and tried mild steel wire instead of SS and the SS wire
broke more easily than the mild steel. I used the SS anyway, as,
well, it's good enough for the FAA (see photo)</p>

you decide to use stainless steel be prepared for it. The
flaring tools are different! Single flares, you can succeed
most of the time but quality control is difficult. Double
flares, maybe once or twice if you are lucky until the tool
breaks. The best advice it don’t use SS unless you have the
right tools or have a shop flare the lines. You should also
install copper cone washers between the SS flare and the
brake line seat. It prevents galling of the seat. Oh… the
washers are hard to find and hard to install; but you can
make them.)</span><span
