Avesta 318/SKNB description: AVESTA 318/SKNb is used for welding titanium and niobium stabilised steel type 17 Cr 11 Ni 2.5 Ti or similar. A stabilised weld metal possesses improved high temperature properties, e.g. creep resistance, compared to low-carbon nonstabilised materials. 318/SKNb shows somewhat better properties than 316L/SKR at elevated temperatures and is therefore recommended for applications where service temperatures exceed 400°C.
