KOVET H-350R is a general purpose rutile coated hard surfacing electrode deposition a tough chromium manganese alloy weld metal sufficiently hard to resist serious deformation under fairly heavy impact and rolling loads, yet with good resistance to medium abrasive ware.  Recommended for hard surfacing applications where maximum hardness consistent which reasonable machine ability is required.  It is also suitable as-buffer layer and for building up multi-layer deposits on badly worn components.  

KOVET H-400R is a rutile coated hardfacing electrode depositing alloyed weld metal with a hardness of approximately 45HR which for many applications can be applied directly on hardenable steels. Particularly this KOVET H-400R is suitable for the reclamation and fabrication of new metal cutting or forming equipment.  

KOVET H-600R is rutile coated hardfacing electrode for surfacing worn parts of civil engineering construction and mining, machinery tube used with out machining. Deposited metal of approximately 55HRc provides high toughness in spite of high hardness and excellent abrasion resistance to medium impact.
