DESCRIPTION
A heavy coated basic type, hydrogen - controlled, iron powder electrode with high deposition efficiency. The electrode deposits weld metal, which is of radiographic quality and meets impact requirements at minus 50ºC.The weld deposit is tough, ductile and is highly resistant to hot or cold cracking even when subjected to high stresses, dynamic loading etc. The deposited weld metal has resistance to ageing hence it is used for critical application in steel plants.
