Weathering steel is ideal for bridges and other structures where access is difficult or dangerous, and where future disruption needs to be minimized. Initial cost benefits : Cost savings from the elimination of any protective paint system may outweigh the additional material costs.
ASTM 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.
The applicable equivalent ASTM specifications for weathering steel are ASTM A588, ASTM A242, ASTM A606-4, ASTM A847 and ASTM A709-50W, other standards JIS G3125, JIS G3114, EN10025 and GB/T4171
ASTM 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.

Technical Advisory Uncoated Weathering Steel in Structures. October 3, 1989. Technical Advisory 5140.22. PURPOSE. To provide engineers with suggested guidelines for proper application of uncoated (unpainted) weathering grade steels in highway structures and recommendations for maintenance to ensure continued successful performance of the steel.
The ASTM International has designated this steel as a "Grade." The most recent comparable grade weathering steel is ASTM A588 and A709-50W. Weathering steel reacts and oxidizes/rusts like standard carbon steel but is different, different due to the added corrosion resistant elements.
Weathering steel, often referred to by the genericized trademark COR-TEN steel and sometimes written without the hyphen as corten steel, is a group of steel alloys which were developed to eliminate the need for painting, and form a stable rust-like appearance after several years' exposure to weather.

chemical composition of former ASTM A709, Grade 70W steel, ASTM A709-9701 and ASTM A709-01 Grade HPS 70W steel. Note the more controlled ranges of allowable alloy elements and lower sulfur, phosphorus and carbon levels for HPS 70W steel, and development of HPS 70W chemistry to the most current specification. HPS 70W steel must be made using a low-
ASTM A588 Grade A/B A709 Grade 50 W. Also known as weathering steel, this grade will be used for products that are exposed to all weather elements. Used in Bridge Steel, freight cars, telecommunication towers, and gusset plates. This has atmospheric corrosion resistance that develops over time to external elements.
A572-50 & A709-50 High Strength Steel Angles When you are looking to purchase Corten angle it will be referred to as ASTM A588 Angle. ASTM A588 covers high-strength low-alloy structural steel shapes, plates, and bars for welded, riveted, or bolted construction but intended primarily for use in welded bridges and buildings where savings in , a709 weathering steel
weathering steel. 3.1.4 High Performance Steels (HPS) ASTM A709 HPS50W, HPS70W and HPS100W steels are products that have F y of 50, 70 and 100 ksi (respectively). In addition, these classes of steels have superior toughness properties compared to non-HPS materials. The production of HPS steel at the mill imposes certain market realities that , a709 weathering steel
Improved weathering properties per ASTM G101 This steel is an improved version of an older and discontinued grade A709 Grade 70W. Advantages The combination of the higher yield strength, weathering properties and reduced preheat requirements can result in significant cost savings both short and long term for bridge owners.
entirely of weathering steel. Specification Specifics ASTM A588 covers the majority of rolled structural shapes produced in weathering steel and can be con-sidered the base specification for weathering steel for building applications. ASTM A709 is used primarily in bridge applications. Among its various grades, Grades
that HPS 70W steel will have superior corrosion resistance than 50W and former 70W, although this is unsubstantiated by tests at this time. Like other weathering steels, there is a potential for atmospheric corrosion rates to increase in applications that subject high performance steel to continuously wet environments 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.
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.
Common weathering steel specifications used in structural fabrication include ASTM A242, A588, A606 and A847. Specifications common to bridge fabrication include ASTM A709 and AASHTO M270. Several manufacturers also use trade names to indicate their unique patented formulations of weathering steel, such as U.S. Steels COR-TEN.
The chemistry for HPS 50W grade steel is the same as HPS 70W shown in the table above. ASTM A709 Grade HPS 50W is contained in A709-01 and is produced using conventional hot-rolling or controlled rolling up to 4" thick in lengths similar to Grade 50W steel. 2.2 Mechanical Property Requirements (ASTM A709-01)
being built with some form of weathering steel. Weathering steel is typically a high-strength, low-alloy steel that, in suit-able environments, forms a tightly adherent protective rust pa-tina that acts as a skin to prevent further corrosion to the steel beneath. Since its development in the 1930s, many U.S. steel
