CLASSIFICATION
AWS/SFA5.1: E 7016-1 IS814: EB5626H3 X
DIN: 8529 ESY4276 MnB, EN ISO 2560-A: E38 3 B 12 H10
DESCRIPTION
A heavy coated basic type, hydrogen - controlled, electrode suitable for welding root passes and for bridging wide gaps. The electrode deposits weld metal which is of radiographic quality and meets impact requirements at minus 46°C. The weld deposit is tough, ductile and is highly resistant to hot or cold cracking even when subjected to high stresses, dynamic loading, passes CTOD test at sub-zero temperature when conducted as per relevant specification.
