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. The three weather grades of 50W, HPS 50W, and HPS 70W have an ASTM G101 enhanced
ASTM A709 Grade 50W Pipe ASME SA709 Corten ASME SA709 Corten Weathering Steel Tube supplier. Carbon and high-strength low alloy steels meant for structural purposes in various forms, plates and bars are covered by specification ASTM A709. These components are first quenched, following which the alloy steel is tempered. The use of these structural plates or ASTM A709-50W Corten Steel Welded Pipe is specifically designed for use in bridges.
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. ASTM A709-50W shall have an atmospheric corrosion index of 6.00 or higher.

Carbon steel filler metals may be used if the weathering steel has a minimum yield strength requirement of 50 ksi and groove welds are single-pass or one pass on each side of the weldment. For fillet welds, this type of filler metal can be used if the welds leg sizes will be less than or equal to 5/16 inch when using solid wire, metal-cored wire or flux cored wires, or 1/4 inch when using stick electrodes.A709 Grade 50W steel grade,A 709 Grade 50W Weathering 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.
