Descrizione
Caratteristiche:
The weld metal contains proper quantity of ferrite in austenitic structure. It provides higher strength and creep strength at high temperature due to higher carbon content. The corrosion resistance against acetic acid, sulphuric acid and phosphoric acid and crack resistance at high temperature can be improved by MO in 316H. It is suitable for chemical plants and LNG.
Applicazioni:
It is suitable for welding stainless 316H and service temperatures up to 700ºC.
Note sull'uso:
1.Preheating normally not necessary.
2.Material with a thickness exceeding 25 mm is preferably preheated up to 150ºC.
3.Interpass temperature should not exceed 200ºC. Re-drying at 120 – 200ºC for min. 2 h if necessary.
