CEWELD


SA 890 SAW Arc Submerged




SA 890

 
CATEGORY 
TYPE 
Solid drawn wire for high tensile steels with yield strength >890 N/mm2.
APPLICATIONS 
Crane, steel, vessel and apparatus construction.
PROPERTIES 

Extreme crack resistant weld deposit due to extra low hydrogen content when combined with Ceweld  FL 155. Developed for welding cold tough, high tensile fine grain steel exceeding a yield strength of 890N/mm2. To obtain the requested mechanical properties the heat input should be kept around 10 KJ/cm. Cooling time (T8/5) must be adjusted by travel speed and preheat temperature.

CLASSIFICATION
AWS 
A 5.28: ER 120 S-G
EN ISO 
14295: SZ4Ni2CrMo
SUITABLE FOR 

S890 TM-pipe steels to StE 890 to S890QL1, A 517, X 120 high-strength fine grain structural steels (low temp) to StE 960 (StE 1100 to 12 mm) to S960QL1 (S1100 to 12 mm)
