LT·E5003 Conform to Standard
GB/T 5117 E5003
ISO 2560-B-E 49 03 A
Specification:J502 is calcium-titanium coated carbon steel electrode. It has very good welding usability that enables it to operate on AC/DC, performs all-position welding, has stable arc, removal of slag is easy and has good bead appearance. Its good mechanical properties give it very good low temperature toughness. During the application, its characteristic of easy maneuverability offers easy striking, easy re-striking and good control of welding speed, which enables the welders to have desired weld path and penetration of the arc.
Purpose:Used for welding all kinds of 490MPa low-alloy structures
