DETAILS
Features/Characteristics
The nominal composition (wt %) of SME 347-16 weld metal is 19.5 Cr, 10 Ni with Nb or Nb Plus Ta added as a stabilizer. Either of these additions reduce the possibility of inter granular chromium carbide precipitation and thus increases resistance to inter granular corrosion. Tantalum and niobium are almost equally effective in stabilizing carbon and in providing high temperature strength. The electrode is rutile type and intended for high temperature service or applications. For welding of Ti-stabilized steels such as ASTM 321 and 347 that exposed to service temperature exceeding 400 °C. Also.
SME 347-16 Welding Rod Uses/Applications
- SME 347-16 welding Electrodes is suitable for joining of stainless steels of similar composition.
- Especially those involving high- temperature service, are adversely affected if the ferrite content to high.
- It is ideal for welding of AISI 304, 304L, 321, 347 and their equivalents.
- Used for the second layer (first layer 309L type) when cladding mild steel.
Re-drying Conditions
To obtain best results Re-dry the Electrodes at 300°C for 1 hour (optionally available in vacuum packed Condition, re-drying not required in this packaging)
