    Bridges - Steel Construction

    Weathering steel is a high strength low alloy steel that in suitable environments forms an adherent protective rust patina, to inhibit further corrosion. The corrosion rate is so low that bridges fabricated from unpainted weathering steel can achieve a 120 year design life with only nominal maintenance. High Strength Copper Steel for Rail Tank Cars to Bridges

    • AbstractIntroductionResultsSummaryBridge ApplicationAuthorsDevelopment of higher strength-higher toughness steels for tank car applications has been a target for many years to improve the overall performance of railroad tank cars. Over the past ten years, three grades of low carbon copper-precipitation-hardened steels have been developed (NUCu-60, NUCu-70 and NUCu-100) in collaborative research between Northwestern University and Ispat-Inland Inc. The two lower-strength grades are produced by air-cooling after hot rolling. The NUCu-60 Grade (Supertough ATMOSPHERIC CORROSION DATA OF WEATHERING Once this capacity of copper steel became known, further research led to the development of WS and thus to High Strength Low Alloy (HSLA) steels [7]. In the 1920's US Steel produced a new family of HSLA steels intended primarily for the railway industry. Finally, in 1933 US Steel

Request A Quote Hot-Dip Galvanizing Weathering Steel American Aug 05, 2003 · The high content of silicon, such as is in ASTM A588 Grade A, is known to promote the growth of iron-zinc alloy layers during hot-dip galvanizing (Grade A has approximately 0.40 Si whereas carbon steel normally has less than 0.02 Si), which ultimately increases the overall coating thickness.

        SSAB high strength weathering steel is optimized for low

        SSAB is now introducing high-strength weathering steel grades 420 ML and 460 ML. When you specify these high-strength grades in bridge construction or to build rolling stock or other structures, you can use less steel yet maintain high strength. Upgrading to these higher-strength steels gives you superior weldability, lower life cycle costs and Standard Specification for Structural Steel for Bridges

        • SpecificationsPurposeAvailabilityExamplesQualificationInternational1.1 This specification covers carbon and high-strength low-alloy steel structural shapes, plates, and bars, quenched and tempered alloy steel, and stainless steel for structural plates intended for use in bridges. Twelve grades are available in five yield strength levels as follows:1.2 Grade HPS 70W [HPS 485W] or HPS 100W [HPS 690W] shall not be substituted for Grades 36 [250], 50 [345], 50S [345S], 50W [345W], or HPS 50W [HPS 345W].

Weathering steels are generally specified to BS EN 10025-5:2004, and have similar mechanical properties to conventional grade

          Steel Alloys and Their Classification - Aerospace Engineering

          Low Alloy Steel - Usually iron base alloys, which can be hardened to high strength. A common steel alloy for use in the 180 to 200 ksi (1 ksi = 1000 psi) strength range is AISI 4130. Another type is AISI 4340, with a strength range from 200 ksi to 280 ksi, which is used in the 260 to 280 ksi range. A very high strength alloy in this family is 300M, which can be used up to 290 ksi. Steel Bridges - an overview ScienceDirect TopicsLightweight and high-strength materials are more suitable for girders. Modern and advanced materials include:1. High-strength concrete. 2. High-strength rebar. 3. High-performance weathering steel:Concrete bridges are more commonly used for the smaller spans, since rust in steel members increases corrosion and maintenance costs.
