711.08 Arc-Welding Electrodes and Fluxes. The following applies to all steel, except for exposed bare ASTM A 242/A 242M and ASTM A709 Grade 50W (A 588/A 588M) steels. For exposed bare ASTM A 242/A 242M and A709 Grade 50W (A 588/A 588M) applications, see Table 711.08-1. A. Manual shielded metal-arc welding. 1.

A709 Gr.50 vs A588 - American Welding Society

The A709 Gr 50 is equivalent to A572 Gr 50. 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 has errors and omissions. A709 Grade 50,A709Gr50,A709Gr50 PLATE - XinsteelASTM A709GR.50 steel plate is a kind of low alloy structural steel which is for building bridges in normal constructions.For a better weathering resistance,generally steel plate A709 Grade 50W is better used for outside situiations.When rolling these steel materials A709 Grade 50,for each reduction of 0.01% below the specified carbon maximum,an increase of 0.06 manganese above the specified

ASTM A588 Grade A/B A709 Grade 50 W Ranger Steel

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. This grade will provide a longer life in applications when exposed to extreme temperatures. ASTM A709 Steel Plate - Grade 36, 50, 50W , HPS 50W , HPS Heavy thicknesses (3-inches or thicker) available at most Leeco Steel distribution centers. Available in standard grades:36, 50 and 50W. Available in high-performance grades:HPS 50W and HPS 70W. Dual ASTM and AASHTO spec certifications are available. Customers can specify A709 grades to meet Charpy test requirement for specific zones and climate.

ASTM Weathering Steel Specifications Central Steel Service

When properly designed and exposed to the atmosphere, A709-50W is suitable for many applications in the bare (unpainted) condition. ASTM A871-65 This specification provides for a 65ksi minimum yield strength and an 80ksi minimum tensile strength plus the atmospheric corrosion resistance of this steel in most environments is substantially better than that of carbon steels with or without copper addition. ASTM-A709 Standard Specification for Structural Steel 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.

Are Quenched and Tempered (Q A709Grade 50W lesotho weldingamp;T) Steels Readily Weldable?

Also denoted by QT or Q/T, these steels are weldable, but care must be taken to adhere to established procedures at all times, as they often have high carbon contents, and thus high hardenability, leading to a hard heat-affected-zone (HAZ) and susceptibility to cracking. The BS EN 10277-5:2008 (old BS 970 Part 3) steels are good examples of these types of steel.

During the welding process, the filler metal type and the manner in which it is applied determines whether the resulting weld will match corrosion resistance or have the same reddish appearance, more commonly known as color match.
