Oct 13, 2020 · The addition of hardening elements helps prevent steel from denting or wearing out when exposed to strong forces or elements. Corrosion Resistance. To increase the corrosion resistance of M270 and A709 steel materials, elements such as phosphorus, chromium and nickel are added to weathering and HPS grades. Preferred Practices for Steel Bridge Design, Fabrication If it is acceptable for the location, use weathering steel (A 709 Grades 50W and HPS 70W) left unpainted. FHWA Technical Advisory T 5140.22 and Section . 126.96.36.199. of this document provide guidelines on acceptable locations. Some TxDOT districts object to the use of weathering steel, so obtain district approval before using weathering steel in a
Weathering steel, is atmospheric corrosion resistance steel, also known by corten steel. It is the material that between normal carbon steel and stainless steel and with low alloy content. So corten steel is the carbon steel that added with copper (low Cu), Chrome (low Cr) elements, these elements exist to bring anti-corrosion performances. Weathering Steels IspatGuruApr 27, 2013 · Fig 2 Change of colour of weathering steel with time. During the design of the structures with weathering steels the important issues are (i) the actual corrosion loss varies with the environment and hence for long-life, corrosion allowance is to be considered, (ii) crevices and water/dirt traps are to be avoided, (iii) rust stains run to adjacent surfaces and cause staining,
