S611643-084 - Hobart Tube-Alloy A250-S 1/8" Hardfacing Sub Arc Wire 600lb Drum

Industrial-Grade Hardfacing for Steel Mill Applications

The Hobart Tube-Alloy A250-S is a premium hardfacing submerged arc wire designed to meet the rigorous demands of the steel industry. Engineered with a modified 420 stainless steel composition, this wire is specifically formulated to combat the extreme conditions encountered by steel mill rolls and continuous caster rolls. In environments where thermal cycling, corrosion, and metal-to-metal wear are prevalent, the A250-S provides a robust solution for extending the service life of critical machinery components.

One of the standout characteristics of the Tube-Alloy A250-S is its ability to produce high-quality, defect-free deposits. The wire is manufactured to ensure high deposition rates, which is essential for large-scale overlay projects where efficiency and speed are paramount. The resulting weld metal is free from porosity and cracks, a common challenge in hardfacing applications involving martensitic stainless steels. This reliability ensures that rebuilt rolls maintain their structural integrity under heavy load and thermal stress.

This 1/8-inch diameter wire is supplied in a substantial 600 lb Auto Pak, designed for automated and semi-automated submerged arc welding setups. The bulk packaging minimizes downtime associated with spool changes, maximizing arc-on time for high-volume maintenance and repair operations. The alloy's composition offers excellent resistance to the specific types of cracking and corrosion found in steel processing, making it the preferred choice for maintenance, repair, and operations (MRO) professionals focused on heavy industrial equipment.

Whether used for single-layer restoration or multiple-layer buildup, the Tube-Alloy A250-S delivers consistent metallurgical properties. It is an indispensable consumable for workshops dedicated to the refurbishment of mining equipment, heavy construction machinery, and primary steel manufacturing assets. By choosing Hobart's specialized formulation, operators can ensure their equipment withstands the harshest operational environments with reduced frequency of repair.
