Flux type: Aluminate-Basic
Classification:
(EN 760: SA AB 1 66 AC H5)
Characteristics
SJ301 flux for joint welding of high quality steel pipes for pipeline transportation systems in the oil and gas industries. Especially recommended for single and multi-wire (up to 5 wires) submerged arc processes in the two- run technique. Very good weld appearance and slag release providing flat welds with low reinforcement and flat weld interfaces free from undercuts. High grain hardness and resistance to abrasion and a low consumption rate with good flux feeding properties in the transport and recovery system.
As a result of low hydrogen levels (less than 5 ml/100 g in the weld deposits) and oxygen levels of about 350 ppm as well as uniform metallurgical behaviour with low silicon and manganese pick-up, constant mechanical properties are obtained even when welding thick-walled tubes in the two-run technique.
Application
Production of longitudinal and spiral welded steel pipe grades L360 or X52 to L555 or X80 according to ISO 3183 / API Spec. 5L.
