Thermanit 25/14 E-309L TIG rod
Classifications high-alloyed
EN ISO 14343-A: AWS A5.9:
W 23 12 L ER309L
Characteristics and field of use
Stainless wet corrosion up to 350 °C (662 °F). Well suited for depositing intermediate layers when
welding cladded materials. Favourably high Cr- and Ni-contents， low C content. For joining unalloyed/
low-alloy steels/cast steel grades or stainless heat resistant Cr-steels/cast steel grades to austenitic
steels/cast steel grades. For depositing intermediate layers when welding the side of plates clad with
low-carbon – non-stabilized and stabilized – austenitic CrNi(MoN) austenitic metals.
