If a building was built in the 60's is it probable that the quality of steel is a higher grade than the steel that's available today? Do qualities of steele fluctuate? Why?

Your subject line mentions p-trap and that would be cast iron (or brass?) not steel, unless you're talking about an under sink p-trap which more than likely would still be brass or chrome-plated brass. What exactly is your situation?

The quality of the brass does change through time. Brass is mixture of metals. One being lead. Almost all building materials were better in the sixties. At the present, and in the sixties, we have two thicknesses of brass traps. The thiner walled p-trap is 20 gauge and the thicker is 17 gauge.
17 gauge last for many many years. Thats why all commercial jobs require 17 gauge.- Vote on answer

What exactly does the "gauge" refer to? The thickness of the brass itself or the thickness of the wall?

It's the overall wall thickness.

Very little lead in plumbing brass. Why not mention the major constituents like copper and zinc?
