Electrodes BOHLER UTP 690 2.5x350mm/4kg/142pcs (37637)

UTP 690 is used for the repair and manufacture of cutting tools, especially for the completion of cutting edges and working surfaces. The coating is highly resistant to friction, compression and impact, even at elevated temperatures up to 550°C. It is also possible to produce new tools by welding on unalloyed and low-alloy base metals (cutting edge plating). UTP 690 has excellent welding properties, a smooth, gently undulating bead appearance and very easy slag removal due to the rutile coating. The flux is equivalent to high-speed steel with increased Mo content. Minimum mechanical properties of weld metal Hardness of pure weld metal approx. 62 HRC Soft annealed 800 – 840°C approx. 25 HRC hardened 1180 – 1240°C and tempered 2 x 550°C approx. 64 - 66 HRC
