A709 ASTM A709 A709 Steel Plate Kloeckner Metals

Kloeckner Metals offers A709 steel plate in grade 50W. This steel plate is often stocked in the flat-rolled, as-in condition. It is excellent for building bridges and similar applications. Advantages/Disadvantages Industries Applications Machining Welding Heat Treatment AASHT M270-50 Material, anyone familier w/ it??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.


ASTM A709 Carbon and High Strength Low Alloy Structural Steel Plates, Shapes & Bars, and Quenched and Tempered Steel Plates for use in Bridges. Available in Grades 36, 50, 50W, HPS70W, HPS100, and HPS100W. Certain grades require special welding techniques. ASTM A709 / A709M - 18 Standard Specification for

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 A709 Steel Plate - ASTM A709 Steel WarehouseASTM A709 Specifications. A709 is the standard specification for structural steel bridges. Covers carbon, HSLA, Q&T, and stainless steel plates, bars, and shapes for structural use in bridges. Includes grades 36, 50, 70, and 100, with designations for enhanced atmospheric corrosion resistance (W).

    ASTM A242. ASTM A242 is a high strength low-alloy structural steel specification with improved atmospheric corrosion resistance. This specification is normally applicable to steel plates through one-half inch in thickness. The atmospheric corrosion resistance of A242 is substantially better than that of carbon steels such as A36 and A572-50 with or without copper addition. ASTM Welding Procedures A36 to A930 - weldrealityFor MIG welding use an argon 10 to 20% CO2 mix. For gas shielded flux cored use a gas mix with 20 to 25% CO2. Ensure mill scale in weld area is removed and the plate is always at a temperature >60F. Keep single pass fillet welds < 1/4 - < 6mm. Use stringer, do not weave unless necessary. For multi-pass welds. use inter-pass temp control. Different Grades of A 709 - American Welding SocietyJul 13, 2009 · "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". (I thought it oughta stand for "seismic", but no one asked me.) 50S is the equivalent (plus some Charpy testing requirements) of A 992, structural shapes.

    HPS 50W:Steels for Bridges

    ASTM A709-01 first added grade HPS 50W. This high performance bridge steel has the identical chemistry as HPS 70W. It will most often be produced by as-rolled or control-rolled practices. ASTM A709 also allows it to be Thermo-Mechanical Controlled Processed (TMCP), with or without accelerated cooling, normalized, quenched Keeping tabs on current ASTM specifications ARE YOU Gr. 50 50 65-100 Gr. 55 55 70-100 A709 36 36 58-80b A1043d 36 36-52 58 50 50-65 65 High-Strength Low-Alloy A572 Gr. 42 42 60 Gr. 50 50 65 Gr. 55 55 70 Gr. 60e 60 75 Gr. 65e 65 80 A618f Gr.
