Selectarc HBMAX

The Selectarc HBMAX electrode is a rutile-basic coated hardfacing electrode designed to provide exceptional wear resistance against metal-to-metal contact, corrosion, and high temperatures. It’s ideal for overlaying and rebuilding machinery parts and tools subjected to impact, compression, and extensive wear, particularly at operating temperatures up to 650°C. The weld deposit boasts thermal shock resistance and can be machined using tungsten carbide-tipped tools. This electrode offers a stable arc, regular drop transfer, and a smooth, consistent deposit.

This electrode is commonly used for rebuilding dies, hot-working tools, molds, continuous driving rolls, mandrels, and forming tools. It’s suitable for a wide range of applications requiring robust wear resistance and high-temperature performance. Typical welding parameters are provided for various electrode diameters and currents. Post-weld heat treatment (redrying at 300°C for 2 hours) and proper preheating of the base metal (150-400°C) are recommended for optimal results.
