A 709 Gr.50W Weathering Steel Description. ASTM A709 Grade 50W equal grade are EN10155 :S355K2G1W,NFA 35-502E 36 WB 4 .A709 Grade 50W is the specification used for steel plate used in the manufacture of bridges. A 709 Gr50W Weathering Steel Delivery Conditions ASTM A709 / A709M - 18 Standard Specification for This specification covers carbon and high-strength low alloy steel structural shapes, plates and bars, and quenched and tempered alloy steel for structural plates intended for use in bridges. Heat analysis shall be used to determine the percentage of carbon, manganese, phosphorus, sulfur, silicon, and copper for the required chemical composition. A tension test shall be used to determine the required tensile

Way:Hot Rolled, Quenched ( Q), Tempered ( T) Techanical Details:Heat Treatment:Normalized, Quenched, Tempered, HIC, Impact Test,.. ( Optional if not provided in rules) Structural Steel Grades:EN 10210 S355J2H. ASTM A709 Grade 50W/A709 Gr.50W high tensile plates ASTM A709 Grade 50W/A709 Gr.50W high tensile plates are also named as ASTM A709 Grade 50W/A709 Gr.50W weathering steel plates, which is famous for its property in atmosphere corrosion resistance. A709 Grade 50W steel plates are widely used in construction machinery, mining machinery, truck, bridges, pressure vessels, etc., structures building. ASTM A709 Steel Plate - Grade 36, 50, 50W , HPS 50W , HPS Heavy thicknesses (3-inches or thicker) available at most Leeco Steel distribution centers. Available in standard grades:36, 50 and 50W. Available in high-performance grades:HPS 50W and HPS 70W. Dual ASTM and AASHTO spec certifications are available. Customers can specify A709 grades to meet Charpy test requirement for specific zones and climate.
Grade 50W [345W], or HPS 50W [HPS 345W] shall not be substituted for Grades 36 , 50  or 50S [345S] without agreement between the purchaser and the supplier. 1.3 When the steel is to be welded, it is presupposed that a welding procedure suitable for the grade of steel and intended use or service will be utilized. ASTM Weathering Steel Specifications Central Steel ServiceASTM A709-50W is a standard specification for structural steel in bridges. ASTM A709-50W covers high strength, low allow steel structural shapes, plates and bars. The atmospheric corrosion resistance of this steel in most environments is substantially better than carbon steel with or without copper addition.

fying ASTM A847 or A1065 Grade 50W. These and other material specifications applicable to rectangular HSS are shown in Table 2-4. Note that A1085 Grade A is hoped to supersede A500 relatively soon. Round HSS. The preferred material specification for round HSS is ASTM A500 Grade C (F y = 46 ksi, F u = 62 ksi). Note that A1085 Grade AA709 Structural, Carbon & HSLA Steel Plate - Chapel SteelA high-strength, low-alloy structural steel plate utilized primarily in the manufacture of bridges. Chapel 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,
