Performance of Early 20th Century High Strength Steels on American Bridges

The early 20th Century witnessed the first wave of high-performance steel alloys used in bridge construction. The primary benefit of two of these alloys, nickel steel and silicon steel, was increased tensile strength compared to standard mild carbon steel. A supplemental benefit of these alloys was the corrosion resistance that each exhibited, which is quite significant now as bridges containing these steel alloys approach 70 to 100 years of service. Production of these alloys ceased decades ago, and since then, little has been written regarding these alloys except for anecdotal and somewhat misleading passages. This paper will discuss the application of these high strength steels and recent case studies of their corrosion-resistant and fracture-resistant properties.
