Apollo B – High-Impact, Dissimilar and Hard-to-Weld Steels

Apollo B Arc Welding Rods – High-Impact Electrodes for Dissimilar and Hard-to-Weld Steels (SMAW) - 2lb Tube

Product Description

Tough, machinable welds for extreme conditions.
Apollo B rods are engineered to join dissimilar steels, build up high-wear parts, and overlay hard-to-weld materials like manganese and stainless. With 105,000 psi tensile strength and 37% elongation, Apollo B offers exceptional impact resistance, ductility, and hot hardness up to 1000°F (538°C).

Ideal for industrial maintenance and equipment repairs, Apollo B deposits can be machined and will work harden to 45 RC, making them suitable as a base layer or final repair on crusher rolls, wedge bars, and valve seats.

Key Features

• 105,000 psi tensile strength
• Work-hardens up to 45 RC
• 37% elongation for superior ductility
• Excellent for joining dissimilar or alloyed steels
• No preheat required on most steels
• Machinable and impact-resistant
• Effective under high heat and wear (up to 1000°F)
• AC or DCEP operation

Packaging & Sizes

• Electrode length: 14"
• Sold in 2 lb, 5 lb, or 11 lb plastic tubes
• Available diameters:
• 1/8"

Welding Instructions

• Clean the work surface and remove all cracks
• Use higher current on first pass when welding over work-hardened areas
• No preheat needed on most steels
• Apply stringer beads rather than weaving
• Use a heavy root pass when joining materials

Applications

• Dissimilar metal joining (e.g. stainless to carbon steel)
• Overlay and buildup on manganese and carbon steels
• Valve seats, crusher rolls, and wedge bars
• Base layers prior to hardfacing (Olympia, Omega, or Zeta recommended)
