A709 Structural, Carbon & HSLA Steel Plate - Chapel SteelChapel Steel stocks A709 Grade 36, A709 Grade 50 and A709 Grade 50W. These grades are often specified with Charpy tests referencing the specific zone or lowest anticipated service temperature. The Charpy tests are specified as non-fracture critical, which is a per-heat test (frequency "H"), or fracture critical, which is a per-plate test

Gangsteel Grade :A709 Grade HPS 70W. Specification:Thickness 8mm-300mm, Width:1500-4020mm, Length:3000-27000mm:Standard:ASTM A709:Standard Specification for Structural Steel for Bridges Carbon and Low-alloy High-strength Steel - Bebon steelsCarbon and Low-alloy High-strength Steel provide greater environmental corrosion resistance and are stronger than convention carbon steel,also very ductile, highly formable and easy to weld.Carbon and Low-alloy High-strength Steel steels are not typically made to meet a certain chemical composition, instead they are known to meet specific mechanical properties.
2.3.1 Topic 2.3 Steel 2.3.1 Introduction Steel is a widely used construction material for bridges due to its strength, relative ductility, and reliability. It is found in a variety of members on a large number of bridges. Therefore, the bridge inspector should be familiar with the various High tensile steel plates JFE Steel Corporation (Japan)ASTM A588 steel plate is a corrosion-resistant steel high-strength low-alloy (HSLA) structural steel plate that is excellent for welding, riveting or bolting in construction applications, primarily welded bridges and buildings where savings in weight or added durability are important.When properly exposed to the atmosphere, A588 is suitable for many applications in the bare or unpainted condition.
