Thermanit JE-308L Si TIG rod
Classifications high-alloyed
EN ISO 14343-A: AWS A5.9:
W 19 9 L Si ER308LSi
Characteristics and field of use
Stainless resistant to intercrystalline corrosion and wet corrosion up to 350 °C (662 °F). Corrosion-
resistant similar to matching low-carbon and stabilized austenitic 18/8 CrNi(N) steels/cast steel
grades. Cold toughness at subzero temperatures as low as –196 °C (–321 °F). For joining and
surfacing applications with matching and similar – stabilized and non-stabilized – austenitic CrNi(N)
and CrNiMo(N) steels/cast steel joining and surfacing work0n cryogenic matching/similar
austenitic CrNi(N) steels/cast steel grades.
