Description
Characteristics:
The weld metal of LKE-309H is a rutile electrode for high temperature service. It is suitable for the welding of AISI Types 309H in all positions.
Applications:
It is suitable for welding stainless 309H and service temperatures up to 700ºC.
Notes on Usage:
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.
