Mac Trode E6818-G
AWS E8018-G
Descriptions & Applications:
A low hydrogen, basic flux coated, low alloy electrode. Using a silicon free, low nitrogen core wire. Suitable for welding all grades of structural steels with a specified minimum yield strength of 460 N/mm². However, it is of special value when the steel/weld metal also needs guaranteed toughness properties at -50°C. Those steels include BS4360 all grades at 50F. All grades ‘plates' to BS1501-225 and all grades ‘forgings' to BS1501-224.
