D502 Hardfacing Electrode
GB/T 984 EDCr-A1-03
Suitable for hardfacing carbon steel or alloy steel shafts and valves operating at temperatures below 450°C.
A titanium-calcium coated 1Cr13 type valve hardfacing electrode. The deposited metal is 1Cr13 semi-ferritic high chromium steel. The hardfacing layer has air-hardening properties, generally requiring no heat treatment, with uniform hardness. It can also be annealed and softened at 750–800°C. When heated to 900–1000°C and air-cooled or oil-quenched, it can be rehardened.

1. Drying Requirement: Electrodes must be baked at 150°C for 1 hour before use and used immediately after baking.
2. Preheat hardfacing parts to above 300°C. Post-weld heat treatment can achieve corresponding hardness levels.
