lower carbon content, and tighter controls on phosphorus and sulfur, which
are detrimental alloy elements. The lower carbon content improves the
weldability of the steel.
The industry has recognized the advantages of designing with the high
performance steels. The first HPS bridge went into service in 1997. As of
