For demanding industrial applications requiring exceptional surface protection, Surfacing Electrodes meeting DIN 8555 (E1-UM-350) deliver critical wear and crack resistance. The TY-C DUR 350 model features a basic coated SMAW electrode design, engineered specifically for hardfacing operations. Its alloy composition generates a robust, work-hardening deposit under impact, significantly extending component service life in abrasive environments. This electrode ensures reliable performance across mining, heavy machinery, and rail sectors where surface degradation dictates maintenance cycles and operational costs.
Manufactured to stringent DIN 8555 (E1-UM-350) standards, these electrodes produce deposits with an austenitic microstructure rich in manganese, chromium, and vanadium. This metallurgical design achieves optimal balance between hardness (≈350 HB) and ductility, preventing crack propagation while resisting intense mechanical wear. The result is a dense, homogeneous overlay capable of withstanding crushing, gouging, and high-stress abrasion，ideal for protecting high-value equipment subjected to extreme operational forces.
The versatility of these Surfacing Electrodes shines in their application range. They excel in rebuilding manganese chromium vanadium alloy components like railway frogs, conveyor rollers, chain support rollers, sprockets, and guide rollers. Their deposit chemistry minimizes dilution concerns when applied to similar base metals, ensuring consistent hardness and bonding integrity. The electrodes perform reliably in both single，layer builds for moderate wear zones and multi layer stacks for severe impact-abrasion scenarios.
Operational efficiency is enhanced by the electrode’s user-friendly characteristics. Its basic coating facilitates smooth, stable arcs with minimal spatter and easy slag removal. Critically, it supports all-position welding (flat, horizontal, vertical, overhead), enabling on site repairs without disassembling machinery. The TY-C DUR 350 also tolerates moderate preheat variations (typically 150–250°C depending on base mass), simplifying field procedures while preventing hydrogen-induced cracking.
DIN 8555-compliant Surfacing Electrodes like the TY-C DUR 350 represent a cost-effective defense against wear-induced downtime. Combining certified wear resistance, crack mitigation, and versatile all-position weldability, they restore critical dimensions and prolong component lifecycles. For industries reliant on manganese alloy parts, this electrode delivers predictable performance, reduced relining frequency, and lower total ownership costs，securing operational continuity in the harshest environments.
