Hardfacing Welding Electrode TWD 65GRZ (Standards: DIN 8555: E 10-UM-65-GRZ/ EN14700:E Fe16) is a high-performance stick welding rod specially designed to withstand extreme sliding mineral wear. Even under harsh conditions of up to 500°C, its weld coating can still maintain unparalleled wear resistance, providing long-lasting and reliable protection for critical components that endure the harshest tests in the cement, steel, brick and tile, and earthmoving machinery industries.
Product core positioning: Born for “extreme wear”
When ordinary wear-resistant materials fail rapidly under the combined effects of high-speed mineral sliding and high temperature, UTP LEDURIT 65, with its extremely high content of special carbides (Mo, V, W, Nb), builds an extremely strong and stable microscopic protective matrix. This makes it the preferred strengthening solution for equipment components handling high-erosive materials such as sintered ore, clinker, and slag, significantly resisting size failure and production efficiency decline caused by wear.

Core advantages and features
Unparalleled extreme wear resistance
By optimizing the high-hardness special carbide (molybdenum, vanadium, tungsten, niobium) system, the weld layer’s ability to resist mineral sliding wear reaches an outstanding level, which can extend the service life of the equipment in extreme abrasive conditions by several times, significantly reducing the cost per ton of material processed.
Outstanding high-temperature working performance
Designed specifically for environments with a maximum working temperature of up to 500°C. The hardfacing layer can maintain high red hardness at high temperatures, with stable structure and minimal wear performance degradation. It is perfectly suitable for high-temperature and high-wear areas such as kiln furnaces, rotary kiln outlets, and clinker cooling zones.
Outstanding welding techniques and construction efficiency
Using spray arc transition, the droplet transition is uniform and smooth, and the welding process is stable and smooth. The weld seam is flat and smooth without slag coverage. In most application scenarios, after welding, there is no need for grinding treatment and it can be directly put into use, which greatly saves construction time and subsequent processing costs.
Extensively applicable to core heavy-duty equipment
Designed specifically to protect core equipment operating in extremely worn-out environments, it is a key consumable material for extending its service life and enhancing operational economic benefits.
Typical application fields
Cement and brick industry: crusher hammers, liners, grate cooler hammers, mixer blades, brick extrusion machine screw blades, etc.
Steel and metallurgical industry: Circulating cooler plates of the sintering plant, revolving-bar screens, crusher rollers, silo lining plates, blast furnace distribution troughs, etc.
Earthwork and mining equipment: The bucket teeth of excavators, the blade plates of scrapers, the chute of conveyors, etc., are the parts that are subjected to severe mineral wear.
