S125732-035 - Hobart Hoballoy 10018-D2 3/32" Stick Electrodes (50lb Can)

High-Tensile Performance for Critical Alloys

The Hobart Hoballoy 10018-D2 is a premium shielded metal arc welding (SMAW) electrode designed specifically for the joining of high-tensile steels and manganese-molybdenum alloys. Meeting the AWS A5.5 classification of E10018-D2, this electrode is engineered to provide weld deposits with a minimum tensile strength of 100,000 psi, making it an essential consumable for industries requiring superior structural integrity and load-bearing capacity. The 'D2' suffix indicates a specific chemical composition enriched with manganese and molybdenum, which enhances the mechanical properties of the weld metal, ensuring it matches or exceeds the base material's strength in critical applications.

One of the standout features of the Hoballoy 10018-D2 is its specially formulated coating. In industrial environments, particularly those involving high heat and humidity, standard low-hydrogen electrodes can be susceptible to moisture pick-up. Absorbed moisture can introduce hydrogen into the weld pool, leading to hydrogen-induced cracking or "cold cracking," which is a catastrophic failure mode in high-strength steels. Hobart has addressed this challenge with a moisture-resistant coating that significantly reduces the rate of moisture absorption, thereby maintaining the low-hydrogen status of the electrode for longer periods during exposure. This feature is particularly valuable in field applications such as offshore rig construction, pipeline repair, and on-site pressure vessel fabrication where climate control is difficult.

The electrode is versatile in its operation, capable of running on both Direct Current Electrode Positive (DCEP) and Alternating Current (AC). This flexibility allows welding operators to utilize the electrode across a variety of power sources and field setups. The 3/32-inch diameter is particularly useful for root passes, positional welding, or thinner sections of heavy-wall pipe and plate. Whether used for single-pass or multiple-pass welds, the Hoballoy 10018-D2 delivers consistent mechanical properties and X-ray quality welds, ensuring compliance with rigorous code requirements in petrochemical, power generation, and heavy construction sectors.
