Deskripsi
Karakteristik:
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.
Aplikasi:
It is suitable for welding stainless 304H and service temperatures up to 700ºC.
Catatan tentang Penggunaan:
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.
