Weldability
1.4034 is not suitable for welding due to its high carbon content. If welding cannot be avoided, preheat to 350 ° C-400 ° C and post heat treatment temperature is about 650 ° C.
Corrosion resistance
DIN EN 1.4034 is not resistant to intergranular corrosion at delivery. Klors u in Z and acid-based medium has good corrosion resistance; the polished surface in the annealed state has good corrosion resistance; It is not recommended to be used in annealed or high temperature conditions to maintain corrosion resistance.
