well, a poor temper (too low temperature) on older steel formulations would often have an unpredictable plastic yield or even become brittle through work hardening and take a "set" which permanently deforms the spring at an inappropriate elastic point. pre-stressed steel going through annealing and tempering takes a large bite out of the ultimate strength of a spring beyond this yield point and as long as the spring isn't compressed or expanded beyond the limit, it should never reach a point of losing strength or taking a set. you can look up young's modulus if you want the math end of things.I wonder where these things come from.
chrome silicate spring steel is virtually immune to this sort of thing, assuming the spring is properly made and used in an appropriate way. even very cheap mags can use this alloy since it's like $0.30-0.80 per foot depending on gauge and if it's enameled, et c, and the typical 1911 magazine spring is around 18 inches long.
