S4 MoSi SAW Arc Submerged




S4 MoSi

 
CATEGORY 
TYPE 
Solid wire for submerged arc welding with high Manganese content and 0,5% Mo.
APPLICATIONS 
Fine grain steels for yield strength aplications exceeding 500 MPa. Often used for pipe welding (X70-X80) when Mn. and Si. content is low..
PROPERTIES 

High Manganese and Silicon content for improved de-oxidation and strength, excellent wetting for increased welding speed with corresponding flux.  Suitable fluxes are depending on the weld metal requirements, in most cases Ceweld FL 155 gives excellent results.
