10 rows · May 17, 2019 · All structural steel will be AASHTO M270/ASTM A709 Grade 36 (F y = 36 A709 Structural, Carbon & HSLA Steel Plate - Chapel SteelASTM A709 A 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.

AASHTO M 270M/M 270-20 - Techstreet

AASHTO M 270M/M 270-20 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. Nine grades are available in four yield strength levels. ASTM A709 / A709M - 18 Standard Specification for Grade 50W [345W], or HPS 50W [HPS 345W] shall not be substituted for Grades 36 [250], 50 [345] 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. Disc Bearings CosmecOur designs are based on using ASTM A709 Grade 50 (AASHTO M270 Grade 50) steel, and ASTM A709 Grade 50W (AASHTO M270 Grade 50W) weathering steel. ASTM A709 Grade 36 (M270 Grade 36) will be considered on demand. The urethane discs are made from polyether urethane compound formulations that meet present AASHTO requirements or requirements

HPS 50W:Steels for Bridges - ArcelorMittal

The ASTM specification A709-01 and later versions allow HPS 50W. The AASHTO Specification M270-02 and later versions allow HPS 50W. Additional Technical Information For further technical information about HPS 50W steel plates, please contact Dylan Alexander at ArcelorMittal USA at +1 610 383 2571 or [email protected] HSS Showdown:ASTM A1085 vs ASTM A500 Atlas TubeMay 15, 2015 · This is the CVN required by the AASHTO M270 (ASTM A709) for all Fracture Critical elements in service temperature Zone 2. Having this minimum CVN required makes HSS produced to this spec suitable for use in structures subject to fatigue, such as pedestrian and vehicular bridges. ASTM A500-13 Grade B does not have a minimum CVN requirement.

High Performance Steel For Highway Bridges

for HPS 70W and conventional AASHTO M270 Grade 50W steel. The brittle-ductile transition of HPS occurs at a much lower temperature than conventional Grade 50W steel. This means that HPS 70W(485W) remains fully ductile at lower temperatures where conventional Grade 50W steel begins to show brittle behavior. High Strength Low Alloy Steel (HSLA) Owen IndustriesThese grades are often specified with charpy tests referencing the specific zone (or climatic region) in which the bridge will be in use. Bridge steels can also be ordered to the ASSHTO M270 Spec referenced as AASHTO M270 Grade 36, AASHTO M270 Grade 50, AASHTO M270 Grade 50W. High Strength Steel Plate - A871 Grade 65 Plate Wholesale The charpys are specified as non-fracture critical which is a per heat test (frequency "H"), or fracture critical which is a per plate test (Frequency "P"). Bridge steels can also be ordered to the ASSHTO M270 Spec referenced as AASHTO M270 Grade 36, AASHTO M270 Grade 50, AASHTO M270 Grade 50W. A709 grade 50 plate Grade and Specification
