StarBlaze HF 400 LH
DIN 8555: E1-UM-350P
30–35 HRc Hardness | All-Position Build-Up | Machinable & Durable
An all-position, basic-coated hardfacing electrode engineered for depositing wear-resistant chromium-manganese alloy weld metal. Designed for parts subject to sliding friction, mild impact, and dynamic surface wear. Delivers a clean, low-spatter arc and forms a tough yet machinable weld deposit, making it ideal for rebuilding worn components in construction, mining, and material handling.
