ASTM A709 - SSABThe 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
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].

FHWA Bridge Inspector's Manual Section 2.3 and 2.4 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
HPS 50W:Steels for Bridges - ArcelorMittalwith HPS 70W; most often use of 50W is sufficient. Size Availability 1/2 to 4 in. (13 102 mm) thick; up to 1500 in. (38.1 m) long (if heat treated, length restrictions of 50 ft. (15.2 m) max. may apply); widths to over 150 in. (3.81 m) depending on overall weight; refer to ArcelorMittal USA Plate offices. Welding
A709 Grade HPS 70W (HPS 485W), known simply as HPS 70W. HPS 70W is defined as steel plate that has: A minimum yield strength of 70 ksi (485 MPa) High levels of fracture toughness (zone 3 minimum) Reduced preheat requirements for welding
Processing Alternatives for Optimized Strength and welding. ASTM A709 HPS 70W steel is a high performance steel with a minimum yield strength of 70 ksi (485 MPa) and it is produced in either quenched and tempered or thermo-mechanical control processed condition for bridge construction.
