Apollo A – High-Strength, Manganese and Wear-Resistant Steel

Apollo A Arc Welding Rods – High-Strength Electrodes for Manganese and Wear-Resistant Steel (SMAW) - 2lb Tube

Product Description

Maximum strength and impact resistance for heavy equipment repairs.
Apollo A rods are engineered to deliver crack-resistant, work-hardening welds on low alloy, manganese, and carbon steels. Built for the most demanding applications, Apollo A provides a 135,000 psi tensile strength weld with 30% elongation and the ability to harden under stress—making it ideal for shock, impact, and abrasion-prone repairs.

Use Apollo A for high-wear applications like crusher hammers, rail frogs, dragline chains, and manganese wear plates. For even greater wear resistance, overlay with hardface alloys like Olympia, Omega, or Zeta.
