Mild Steels Electrodes
ES 7024 A5.1: E 7024 / EN 499: E 42 0 RR 53
Description
ES 7024 is a heavy coated, high efficiency rutile iron powder electrode. It gives a metal recovery of about 165 % due to high iron powder content in its coating. It is particularly suitable for fillet welding of thick plates. It gives smooth weld bead appearance with a soft arc. The slag is easy to remove, resistant to high current, economical for flat fillet and gouging welding. Recovery 165.
