JD: Do you know of any resource which has comparative %'s of the elements in different steel wire from different manufacturers? Or is this information just too difficult to come by?

Comments? I have no direct experience of it but am interested in others' experience of it, which I pick up from various quarters, including on this list, and I have so far had no reason on that basis to be convinced of its qualities, which are very vaguely advertised. I keep an open mind on it, but am more interested in cast steel wire of various tensile strengths from other sources. For strings in the low bass of short pianos, where the tension is normally a low percentage of the yield point, I think almost certainly a core wire of wire with lower tensile strength can give improved tone and I am about to take my experiments a little further, since the little work I have done so far is quite promising. For much of my work, however, at least as regards bass string making, I need wire that has a _higher_ tensile strength, such as the old Poehlmann wire, since many old scales from good makers such as Schiedmayer,Blüthner, Rittmüller etc. were designed for higher tensions than the R wire will withstand. I have a suspicion that what is lacking in modern wires is (certainly) not chromium but more likely nickel. We shall see.
