Medium and High Tensile Steel
SUPRATHERME
AWS: SFA 5.1 E7018
EN ISO CODE: 2560-A E 42 3 B 3 2
Supratherme is an 7018 electrode which is a heavy coated low hydrogen, iron powder type electrode ideally suited for producing tough and ductile welds of radiographic quality in boilers, pressure vessels and heavy structures subjected to dynamic loading. This 7018 electrode has a metal recovery of about 115%. Some typical applications include heavy structures subjected to dynamic loading and impact, highly restrained joints, coaches, wagons, penstocks, boilers, pressure vessels, earthmoving machines, etc.
