Never seen a SS line or SS fittings blow, but I've seen brass fittings fail at 1k+ psi but not the line itself. Seen plenty of micro and macro lines blow out, also seen plenty of their fittings fail as well.
Your mag valve will take 3k input and survive, it'll vent all the over pressure out the tail end. The braided SS I use and the steel fittings are all rated to 3k+ in the event that my reg dumps and the full volume in the tank hits the mag's valve. I've had that happen to me personally once and seen it happen to a good friend of mine twice. All part of the dangers of working with compressed air.
Also had a friend of mine shred his fingers when his line sprung a leak at 1k psi, he put his hand over the leak in game and the air pressure sliced right into his hand like a scalpel, cut right to the bone. Definitely scary stuff, so I plan for the worst case scenario as best as I can by going with line and fittings that can take the pressure.
