Submerged Arc Welding (SAW)

AWS A5.17 : EH12K
EN ISO 14171-A : S3Si

Low carbon, high manganese, low silicon general purpose submerged arc wire.


OE-SD3 is a coppered SAW wire for welding unalloyed steel grades. The wire is especially designed to be used in multi-run applications with OP 121TT to obtain high charpy toughness values even down to -60°C. When OE-SD3 is combined with OP 41TTW the weld metal will keep its strength properties even after a very long PWHT (e.g. 16 hrs at 620 °C). 


  • A low carbon, high manganese, medium silicon wire primarily designed to be used in multirun conditions
  • Capable of producing weld deposits with impact properties exceeding 47 J at -62°C when used with OP121TT in As Welded or after post weld heat treatment conditions
  • Actual (Type 3.1) certificates for each lot of wire showing chemical composition are available
  • Industry standard grade covering a very wide range of requirements
