A709 Grade 50S steel plate A709 Grade 50S steel grade is a high strength low alloy structural carbon steel used in building bridge projects. Compare A709 Gr.100, and A709 Gr.50w grade, A709 Gr.50S has a lowest yield strength in 345Mpa in usual. A 709 Gr.50S requests killed or semi-killed in manufacture.
ASTM A709 - SSABASTM A709. The ASTM A709 is the Standard Specification for Structural Steel for Bridges and encompasses carbon, high-strength low-alloy, and quenched and tempered alloy steels used as structural plates in the construction of bridges. SSAB offers the following five grades of A709; 36, 50, 50W, HPS 50W and HPS 70W.

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 , 50 , 50S [345S], 50W [345W], or HPS 50W [HPS 345W]. Grade 50W [345W], or HPS 50W [HPS 345W] shall not be substituted for GrM270 vs. A709:Grade Comparison Leeco Steel, LLCOct 13, 2020 · Both M270 and A709 have weathering grades represented by a W, as with A709 Grade 50W which contain additional alloys that help them better endure extreme weather conditions. A709 also has high-performance standard (HPS) grades, which offer a balance of strength, weldability, corrosion resistance and ductility.
These properties make ASTM A709 Grade 50W I Beam ideal for applications such as bridges, and is a standard material employed by the American Association of State Highway and Transportation. The ASTM A709 Grade 50W I Beam maintains a tensile yield strength of 50,000 psi and an ultimate tensile strength of 65,300 psi.
