 Characteristics and field of use 

  UTP LEDURIT 65 is suited for highly abrasion resistant claddings on parts subject to extreme 
 sliding mineral abrasion, also at elevated temperatures up to 500° C. The extremely high abrasion 
 resistance is reached by the very high content of special carbides (Mo, V, W, Nb). Main application 
 fields are surfacings on earth moving equipment, working parts in the cement and brick industry as 
 well as in steel mills for radial breakers und revolving-bar screens of sintering plants. 
  
  UTP LEDURIT 65 has an even droplet transfer in the spray arc. The smooth welding bead is 
 without slag covering. In general there is no need for any finishing by grinding. 
  
  Recovery approx. 265 %. 
  
  Hardness of the pure weld deposit                                                                                                approx. 65 HRC 
  1 layer on steel with C = 0,15 %                                                                                                 approx. 58 HRC 
  1 layer on high Mn-steel                                                                                                         approx. 55 HRC

 Welding instruction  

  Hold stick electrode as vertically as possible, keep a short arc. For multipass applications a cushion 
 layer with UTP 630 is recommended. Redry stick electrodes that have got damp for 2h/300° C.
