DETAILS
Features/Characteristics
The composition of SME 309L-16 weld metal is the 23.5 Cr, 13 Ni, same as that deposited by E309 Electrodes, Except for the lower carbon content. The 0.04 % maximum carbon content of these weld deposits ensure a higher ferrite content than the E309H, usually greater than 8FN and reduces the possibility of inter granular carbide precipitation. This thereby increase the resistance to of inter granular corrosion without the use of niobium (columbium). E309L deposits are not as strong at elevated temperature as the niobium – stabilized alloy or E309H deposits.
SME 309L-16 Welding Rod Uses/Applications
- Welding of AISI 309L type
- Welding of similar and dissimilar steels, eg. stainless steels to mild steels
- Joining SS to low alloy steels or carbon steels.
- Deposition of buffer layer on carbon steel or low alloy steels before deposition of 18/8 type of weld metal.
Re-drying Conditions
To obtain best results Re-dry the Electrodes at 300°C for lhour (optionally available in vacuum packed Condition, re-drying not required in this packaging)
