8600.5655S - Josef H60 Hardfacing Stick Rod 5.0mm - High Abrasion Resistance

High-Performance Abrasion Resistance

The Josef H60 5.0mm Hardfacing Electrode is a premium consumable engineered specifically for industrial applications requiring superior resistance to severe abrasion and moderate impact. Manufactured to meet the rigorous demands of the mining, quarrying, and earthmoving sectors, this electrode deposits a weld metal with a martensitic structure containing hard carbides. With a nominal hardness of approximately 57-60 HRC (Rockwell C), the H60 is the ideal solution for extending the service life of wear parts that interact with abrasive media such as sand, rock, gravel, and coal.

This 5.0mm variant is designed for high deposition rates, making it suitable for resurfacing large components where efficiency and speed are critical. The coating is formulated to provide a stable arc on both AC and DC+ currents, ensuring consistent bead formation and minimal spatter. While the deposit is extremely hard, it maintains sufficient toughness to withstand moderate shock loading without spalling, provided proper welding procedures are followed. It is particularly effective for overlaying carbon steels, low alloy steels, and austenitic manganese steels.

Technical Specifications and Usage

The Josef H60 requires specific handling to maximize performance. Due to its high hardness, the weld deposit is not machinable by conventional cutting tools and must be finished by grinding if a specific profile is required. For base metals with high carbon content or thick sections, preheating is recommended to prevent underbead cracking. The electrode is best utilized in the flat and horizontal positions to control the weld pool effectively.

• Hardness: 57-60 HRC (depending on dilution and layers)
• Diameter: 5.0mm (approx. 3/16")
• Current: AC / DC+ (Reverse Polarity)
• Microstructure: Martensitic with Carbides

Operators should limit buildup to two or three layers to avoid stress cracking in the deposit. If more buildup is required, a buffer layer using a softer, more ductile electrode (such as a specialized buffer rod or low-hydrogen 7018) should be applied first. This strategic approach ensures the hardfacing layer remains intact under operational stress.
