DETAILS
Features/Characteristics
The Nominal Composition of SME E309-16 weld is 23.5Cr, 13Ni with carbon levels allowed up to 0.15 % and typical ferrite levels from 3 to 20 FN. Electrodes of this composition are used for welding similar composition in wrought or cast form. They are also used for welding similar steels, such as joining Type 304 to carbon or low alloy steel, welding the clad side of type 304-clad steels, making the first layer of a 308 weld cladding and applying stainless steel linings to carbon steel shells. Embrittlement or cracking can occur if these dissimilar steel welds are subjected to a post weld heat treatment or to service above 370 °C. occasionally, they are used to weld type 304 and similar base metals where sever corrosion conditions exist requiring higher alloy weld metal.0
SME 309-16 Welding Rod Uses/Applications
- SME309-16 electrodes suitable for joining dissimilar metals such as 18Cr-8Ni stainless steel to mild steel and welding clad surfaces of steel.
- SME309-16 is primarily intended for welding heat resistant austenitic Chromium-Nickel steels of similar analysis such as AISI 309 or 309S.
- SME309-16 is such as joining Type 304 to carbon or low alloy steel, welding the clad side of type 304-clad steels.
- Used for welding similar composition in wrought or cast form.
Re-drying Conditions
To obtain best results Re-dry the Electrodes at 300°C for 1hour (optionally available in vacuum packed Condition, re-drying not required in this packaging)
