Solid drawn copper coated wire for the SAW process
Applications
Pipe work; offshore, pressure vessels, bridge, crane building, apparatus, and steam turbine construction.
Properties
Excellent mechanical strength and welding properties due to a increased manganese and silicon content. S3Si is best to be used with FL 155 high basic agglomerated flux to obtain neutral action on metallurgical chemistry and excellent subzero impact properties down to -60°C.
