E7024

According with GB E5024
Corresponding with AWS E7024

Introduction: E7024 is high efficiency carbon steel electrode with iron powder titania type coating. The deposition efficiency is approximately 150%. AC/DC Suitable for angle/fillet welding in the downhand position, downhand welding and flat fillet welding. It has stable arc, fewer spatters, good slag detachability and neat welding appearance.

Applications: Applicable for welding carbon steel and low-alloy structures, such as A, B and D steel, ships, locomotive vehicles, boilers of 16Mn type, etc.

Instructions:
1.Any stains on the welding surface, such as rust, oil stains, moisture, etc., must be cleared away before welding.
2.The electrodes must be baked under 180~200℃ for an hour before welding due to long time of storage.

Packing details: In carton of 20kgs/net, consisting of 8 boxes x 2.5kgs for 2.5mm, & 4 boxes x 5kgs for other sizes.

With/ without pallets (Fumigation-free pallets) upon customer’s request.
