I think it's something to do with the microstructure of high strength steels. 753 is the same alloy as 531, but the heat treatment regime is different, leading to a different microstructure which gives it the high strength but also makes it more vulnerable to hydrogen embrittlement. I think typical 531 guages are actually run at a higher proportion of UTS in service, so the thinner walls of 753 don't seem to make it more likely to fail.

Interesting stuff :)
