SECHERON 310H Nb

AWS: SFA

EN ISO CODE:

Austenitic Heat resistant cast steel electrode depositing 0.4%C-25%Cr-25%Ni and Nb in weld metal. Excellent operating characteristics. Fully austenitic stainless steel weld metal. Weld metal possesses excellent mechanical properties and resists scaling at high temperatures up to 1200°C. Ideal for welding similar stainless steels in cast form like DIN EN GX40CrNiSiNb24-24, GX30CrNiSiNb24-24. Also used for repair of similar grade casting.
