Equivalent Materials

This material data has been provided by Sandvik Materials Technology.

"Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.

Technological properties

Property
Welding

The weldability of Sandvik 8RE18 is good. Welding must be carried out without preheating and subsequent heat treatment is normally not required. Suitable methods of fusion welding are manual metal-arc welding (MMA/SMAW) and gas-shielded arc welding, with the TIG/GTAW method as first choice.


For Sandvik 8RE18, heat input of <2.0 kJ/mm and interpass temperature of <150°C (300°F) are recommended.


Recommended filler metals:

  • TIG/GTAW or MIG/GMAW welding
    • ISO 14343 S 22 12 H / AWS A5.9 ER309Si (e.g. Exaton 24.13.Si)
  • MMA/SMAW welding
    • ISO 3581 E 22 12 R / AWS A5.4 E309-17
