ESAB OK 55.00 E7018-1H4R AWS A5.1/ASME SFA 5.1 - 3/32" (2.4 mm) x 14" (355 mm) SMAW Electrodes (9 lb Container)
OK 55.00 is an exceptional, all-position, low hydrogen basic electrode, particularly suitable for critical applications requiring exceptional impacts at low temperatures. This electrode provides a smooth, stable arc with very low spatter. Excellent arc starting is enhanced by a special graphite tip on the electrode.
The complete slag coverage provides easy removal and minimal post weld cleanup. OK 55.00 is intended for a wide variety of carbon, low alloy and hardenable steels. The weld metal is also very resistant to hot cracking. OK 55.00 meets the requirements of 4 mL diffusible hydrogen content in 100 g of deposited weld metal. In addition to standard packaging, OK 55.00 is available in VacPac™ packaging to ensure the lowest possible moisture content and eliminates the need for costly rebaking procedures.
