ASME SFA A 5.9: ER316LSi
EN ISO 14343-A: 19 12 3 L Si
Werkstoff Nr.: 1.4430
Description and applications*
Austenitic stainless steel filler metal with a low carbon content, which reduces the possibilities of intergranular carbide precipitation, while increasing the resistance to intergranular corrosion without the use of stabilizers such as niobium or titanium. The higher silicon content improves the usability of the filler metal in the gas metal arc welding process.
The presence of molybdenum provides creep resistance in a halide atmosphere. It is slightly magnetic. Good general corrosion resistance.
This grade may be used for:
• welding low-carbon molybdenum-bearing austenitic alloys;
• joining and surfacing of stainless steels type 316, 316L and 316Ti;
• applications as capweld for the clad side of plates having equivalent coating;
• applications for food processing and chemical industry;
applications for household (e.g. hot water tanks), building (e.g. architectural and roofing) and ship building;
• applications where a very good corrosion resistance is required, such as in acid media a/o in chlorinated solutions.

Marking
Each filler rod for GTAW welding is durably marked with an identification traceable to the unique product type. Welding filler materials wound on spools or in coils are durably marked on the coil or spool with an identification traceable to the unique product type.
The outside of each unit package is suitably labelled with at minimum the following data: grade, diameter, heat, lot no., classifications.
CE marking type-testing performed and available.
Customized labels are available upon request.
