ES 68  / EN 14700: E Fe 5 B


ES 68 It is a basic coated electrode. Molibdenum high - speed steel type designed for building up on items that are subject to EN 14700 severe abrasion and more than average impact; Preheating temperature 200°C - 300°C. Resistant to service temperatures of up to 500°C. Metal recovery % 135. Re-drying is 300°C min. 2 h.

It is designed for shear blades, extrusion rams, tampers, ripper, teeth and coal planes. It is used for the repair ana production of cutting tools, particularly for building - up cutting edges and working surfaces. The deposit is highly resistant to friction corrosion and impact. The production of new tools by using non-alloy and low-alloy base metals is also possible. The weld metal deposit is equivalent to a high speed steel with increased Mo-content.
