Hardfacing Electrodes

D&H 630H

D&H 630-H is a medium coated rutile type hardfacing electrode depositing an air hardening weld metal resistant to severe abrasion and moderate impact. Ideal for hardfacing applications to combat severe abrasion combined with moderate impact. Typical applications include dredger bucket lips, plough shares, excavator teeth, conveyer buckets, etc.

Precaution

1. Ensure the electrodes are dry. Re-dry the electrodes at 150°C for one hour.
