Diametr: 16,5х4,2 mm

Protection: selfshielding

Type - metal cored
Design: tubular, overlapping


General characteristics

The strip is designed for depositiong by the automated open arc welding process a high alloyed wear-resistant weld metal on steel parts and plates exposed to severe mineral abrasion combined with moderate impact. The strip is used for hardfacing protective sheets of mining equipment and quarry machinery of various purposes. (450 °С)
