FAMC-430LNb
详细说明
Flux cored wire
Performance and application
Weld deposit metal low carbon ferritic stainless steel metal powder cored wire containing 17%Cr and Nb for welding similar ferritic stainless steel .
FAMC-430LNb is a wire developed for exhaust system in automotive industry, the wire is used in parts resistant to corrosion and thermal fatigue.
When FAMC-430LNb is used for multi-layer and multi-pass welding of thick and heavy duty parts, it is required to preheat 150-250℃ and do post-weld treatment of 690℃.
