In the harsh environments of the power generation world, even everyday jobs aren’t simple. Fortunately, your choice of a welding and cutting manufacturer is. As the global authority on welding and cutting, ESAB offers the broadest selection of world-class products that meet the tough demands of the industry. From turbine plants to nuclear containment vessels, choose ESAB for powerful solutions.

Creep resistant steels were originally developed to provide improved strength at elevated temperatures. These creep resistant steels were metallurgically designed with additions of chromium, molybdenum and other similar alloys to produce the needed strength and creep resistance required in most steam generating facilities. Applications include heat exchangers, header systems, and associated piping within a power generation facility. Some of the most common grades of creep resistant steels include P11, P22, P5 and P91. Each of these grades has a varying amount of Cr-Mo and other assorted alloys added. Creep resistant steels require the use of comparable filler metals that perform at the same level as that of the steel. It is essential that the choice of filler metals complement the steels while optimizing the creep resistance. In addition, the mechanical properties of the filler materials should adequately produce the toughness needed during the start-up phase of the plant equipment.

Because of the wide variety of creep resistant steel types, the selection of filler materials is also varied. Historically products such as 1.25% Cr, .5% Mo or 2.25% Cr, 1% Mo would have been used. Today however, due to the increased demand for energy, utilities are operating their facilities under peak load conditions causing them to choose another grade such as P91 over one of the other creep resistant steels. The designation most often associated for the applicable filler metals for welding P91 grade steels is a “B9”. ESAB offers a complete line of “B9” filler metals for the SMAW, GTAW, FCAW and SAW processes. Each of these products is tested in accordance to the respective AWS specification and can be certified to the respective ASME specification, if need be. Each lot of material is lot tested and certified prior to the sale. If additional testing is required, ESAB can accommodate such testing. Throughout the years, the Atom Arc®, Arcaloy® and Dual Shield® brand names have been synonymous with both fossil fuel facilities and nuclear power plants. The engineering design built into these products has provided fabricators with the highest level of reliability possible. The technical information contained within this catalog provides the supporting data to substantiate our vast knowledge and experience in the development of products to support the power generation industry. Since all such product is produced in accordance with the ASME Quality Assurance System, customers can take comfort in the fact that these products meet or exceed their most stringent specifications. Feel free to contact us for further information or to discuss a specific application.

Dual Shield 7000-A1 is an all-position flux cored electrode recommended for 0.5% Mo steels. It is used in the fabrication and erection of boilers, pressure piping and tubing, and other pressure vessel applications. Shielding gas of 100% CO2 and 75% Ar, remainder CO2 may be used. A 75% Ar/25% CO2 shielding gas mixture is recommended to improve arc characteristics, increase wetting action, decrease penetration, and provide easier arc control for outof-position welding. The weld metal analysis is similar to an E7018-A1 low hydrogen electrode. AWS/ASME SFA 5.29: E81T1-A1C/A1M
