D507 is specifically designed for cladding shafts and valves made of carbon steel or alloy steel. It is highly effective for components where the surfacing temperature remains below 450 °C.

• Electrode Type: Surfacing electrode with low hydrogen sodium coating.
• Metal Composition: Surfacing metal consists of 1Cr13 semi-ferrite high chromium steel.
• Hardfacing Properties: Features air quenching characteristics; generally does not require post-weld heat treatment.
• Hardness Uniformity: Provides consistent hardness across the surfacing layer.
• Heat Treatment: Can be annealed/softened within the 750°C - 800°C range.
• Versatility: Dual-purpose functionality with an excellent welding process.
• Re-hardening: Can be re-hardened after air cooling or oil quenching when heated to 900-1000°C.
• Polarity: DC reverse connection is available for optimal results.
