DIN 8529          E -Y-6975 Mn 2NiCrMo B H5

AWS/ASME SFA-5.5                 E 10018-G-H4

 

Application / Properties: Electrode for producing crack-free and tough welded joints. Weld metal is extremely metallurgical purity having a very low hydrogen content. Owing to its double covering (up to 3.25 mm SǾ), the electrode gas a stable and concentrated arc, thus being well suited or positional welding. Welds are of X-ray quality. If normalizing is required after welding 1292N shall be used.

Materials:

Heat-treated fine grain structural steels e.g. EStE 620, EStE 690 and others. With high heat input and/Or stress

relieving (thicker sections) 1432N maybe required.

 

 

Rebaking : required at 300°C to 350°C for 2hrs.
