DIN 8555: E1-UM-350
For Impact & Moderate Abrasion | Machinable Weld Deposit | No Redrying Required
A rutile-coated air-hardening MMA electrode formulated for buildup and wear-facing applications subject to impact and moderate abrasion. Produces a machinable weld metal with 37–40 HRc hardness, making it suitable for shafts, rollers, wheels, sprockets, and general rebuild jobs. Weld metal contains chromium-manganese alloy for durability under shock loading.
