The answer is yes you can, unless you are working with a contract requiring otherwise. I normally run D1.5 PQRs with A588/A709-50W so that the test will qualify the lesser grades as well. I would carefully review the A588 MTR to be sure that the material fully meets ALL requirements of A709, because sometimes the documentation A709 Grade 50W steel, A709 Grade 50W price - Steel a709grade 50s the gambia welding WeldingBridge 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 Structural, Carbon & HSLA Steel Plate - Chapel Steel
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. The Charpy tests are specified as non-fracture critical, which is a per-heat test (frequency "H"), or fracture critical, AASHT M270-50 Material, anyone familier w/ it??Jun 26, 2008 · Jul 04, 2008 · ASTM A 709 Gr. 50 is basically A 572 Gr. 50 plus Charpy requirements. A 709 and M 270 explicitly state that particular grades meet or exceed the requirements of A 36, A 572, A 588, A 992, etc. D1.5 discusses the AASHTO & ASTM specs. D1.1 doesn't mention AASHTO specs at all; I guess they figured only the bridge people would ever be messing around with AASHTO specs.AASHTO M 270M/M 270 - Standard Specification for a709grade 50s the gambia welding WeldingJan 01, 2020 · Grade 345W [50W], 345CR [50CR], or HPS 345W [HPS 50W] shall not be substituted for Grade 250 , 345 , or 345S [50S] without agreement between the purchaser and supplier. 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.
