One solution is to normalize your own sheet - apparently it IS
possible to get tempered 4130.

Even the annealed stuff is in short supply. Last time I checked with
Dllsburg (about 10 days ago) he sad - maybe - in a month.

But I've been wondering if the solution isn't High Strength Low Alloy
(HSLA) steels. I know nothing about their weldability compared to
4130, but I do know that tons and tons of the stuff are used in cars
and industrial equipment.

This is where my wanderings have lead me. Welding could be different.

I know most auto manufactures prohibit gas welding the stuff. MIG or
TIG is OK and brass should not be a problem as long as the temp stays
low enough. Some of the HSLA's apparantly are highly corrosion
resistant as well.

Brazing high strength alloy steel components of automotive bodies is
STRICTLY FORBIDDEN. Mig and tig are acceptable if done to
specifications - spot welding is most common.

ASTM A606, A1011, A1008 and ASTM A715 are specs of some steel that
might work. Supply should not be a problem in thicknes between .020"
and .125"
