Welding Electrode HF-600 KOBE STEEL is a robust solution for abrasive and wear-resistant applications based on martensite. Ideal for heavy industries such as construction, mining, and heavy equipment.
JIS Z3251 DF2B-600-B
HF-600 welding electrode from Kobe Steel is a special hardfacing electrode designed to provide maximum protection against heavy wear due to abrasion and impact.
With its high alloy content and special formulation, HF-600 is capable of producing a high-hardness weld layer of around 55–60 HRC, ideal for extending the service life of components operating in extreme environments.
These electrodes provide excellent arc stability, minimal spatter, and clean, strong welds.
Suitable for maintenance and re-coating of various industrial equipment such as excavator buckets, bulldozer blades, crusher plates, and other heavy machinery components.
The HF-600 is a reliable solution for the mining, construction, and manufacturing industries that require superior welding performance with exceptional wear resistance.
