ASME SFA A 5.9: ER316LMn
EN ISO 14343-A: 20 16 3 Mn N L
Werkstoff Nr.: 1.4455
Description and applications*
Fully austenitic stainless steel filler metal with typical ferrite content of 0.5 FN maximum. One of the primary uses of this filler metal is for the joining of similar and dissimilar cryogenic steels for applications down to -269°C. This filler metal also exhibits good corrosion resistance in acids and seawater, and it is particularly suited for corrosion conditions found in urea synthesis plants. It is also non magnetic. The high Mn-content of the alloy helps to stabilize the austenitic microstructure and aids in hot cracking resistance.
This grade may be used for:
• welding, repairing and overlaying of grades of stainless steel like type 316L when weld metal ferrite is needed to be low.;
• applications in cryogenic industry to obtain low impact toughness and high strength.
