Sandvik 19.9.LR (Covered electrodes) Sandvik 19.9.LR is a covered chromium­nickel electrode with rutile­acid coating for welding of steels of ASTM 304 types as well as overlays giving 308 type composition.

The electrode has excellent arc stability and fast burn off rate with minimal stub loss. It is also characterized by improved moisture resistance, self peeling slag, easy post weld finishing. Sandvik 19.9.LR gives smooth uniform beads and works in any standard weld position.

Applications

Sandvik 19.9.LR is used for welding steels of the following types: UNS

S30400, S30403, S30409 and S30453

ASTM

301, 304L, 304LN, 304 and 302

In cases where creep strength is of secondary importance Sandvik 19.9.LR is suitable for welding stabilized austenitic steels, e.g. ASTM 321 and 347. When a weld metal similar to the parent metal is not required Sandvik 19.9.LR can be used for welding ferritic and martensitic steels.

Sandvik 19.12.3.LR (Covered electrodes) Sandvik 19.12.3.LR is a covered chromium­nickel­molybdenum electrode with rutile­ acid coating welding of steels of 316 types as well as overlays giving 316 type composition.

The electrode has excellent arc stability and fast burn off rate with minimal stub loss. It is also characterized by improved moisture resistance, self peeling slag, easy post weld finishing. Sandvik 19.12.3.LR gives smooth uniform beads and works in any standard weld position.

Applications

Sandvik 19.12.3.LR is used for welding steels of the following types: UNS

S31600, S31603, S31653, S31609 and S31635

ASTM

316, 316L, 316LN, 316H and 316Ti

In cases where creep strength is of secondary importance, Sandvik 19.12.3.LR is suitable for welding of corresponding stabilized austenitic steels. When a weld metal similar to the parent metal is not required, Sandvik 19.12.3.LR can be used for welding ferritic and martensitic steels.

Sanicro 69 (Covered electrodes) Sanicro 69 is a covered electrode with basic coating for corrosion­resistant overlays on most low­alloy and stainless steels. It is also used for welding of alloys of Alloy 690 type (e.g. Sanicro 69) and dissimilar joints.

The electrode has good welding properties and is well suited to joint welding, as well as overlay welding.

Sanicro 71 (Covered electrodes) Sanicro 71 is a covered electrode with basic coating and normal metal recovery for welding of NiCrFe alloys, 9% Ni steels as well as nickel­alloyed steels for low temperature use. It is also used for dissimilar joints, such as stainless steel and NiCu alloys to carbon steel and nickel alloys. Sanicro 71 is characterized by little spatter and very good slag removal.
