説明
特徴
Rutile-basic coated electrode for welding of creep resistant CrNi-alloyed austenitic stainless steels such as 304H. Controlled ferrite content of 3 – 8 FN. The deposit is resistant to embrittlement and scaling. Service temperatures up to 700ºC. Excellent weldability in all positions except vertical down.
アプリケーション
It is suitable for welding stainless 304H and service temperatures up to 700ºC.
使用上の注意
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.
