AWS A5.9
AWS Class ER316/316LSi
ASME SFA 5.9
UNS S31688
Description:
ER316LSi is a filler metal that is mainly used for welding low carbon molybdenum-bearing austenitic alloys. This alloy contains a low carbon content of a maximum 0.03%, which allows for a reduced likelihood of intergranular carbide precipitation without the use of stabilizers. ER316LSi is similar to ER316/316L except for its higher silicon content. The higher silicon content allows for ease in welding and a smooth bead appearance. ER316LSi is good for applications in chemical industries, shipbuilding, and industries where a very high resistance to corrosion is needed.
