A709 Grade 50W steel is a standard specification for structural steel in bridges with weathering capabilities. With a corrosion index of 6.0 or higher, ASTM A709-50W has substantially better atmosphere corrosion resistance than carbon steels even with the addition of copper. A709 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,

ASTM A588 ASTM A588 is a high strength low-alloy structural steel specification with improved atmospheric corrosion resistance for structural steel shapes such as angles, channel and beams, as well as steel plate and bars.
Jul 13, 2009 · Practically, they are a handy mnemonic for the type of steel. "W", as you said, stands for "weathering". A 709 Gr. 50W is equivalent to A 588 (except the A 709 carries some additional Charpy testing requirements). "S" stands for "structural". Keeping tabs on current ASTM specifications ARE YOU is ASTM A709, which is an umbrella standard that assembles ASTM A36, A572, A992, A588 and three high-performance steel (HPS) grades into a convenient single standard for bridge designers and fabricators.
