Outlaw i should have added 4100 series cromoly to the list since that's what most roll cages are built with. Even with the cromoly mat'l that we use in racing, we don't use the very best cromoly. There's about 10 different mIL specs for cromoly for the aircraft industry, and the automotive industry uses the cheapest grade, except some crankshaft makers like Wienburg, who's cranks cost around $4,000.00 VS the ones that we buy for $400.00 to $600.00.
Zip.
