SA 309LNb strip ESAW Electroslag




SA 309LNb strip

 
CATEGORY 
TYPE 
Chromium-Nickel-Niobium based welding strip.
APPLICATIONS 
Boilers, vessels, tube cladding, valves etc.
PROPERTIES 

Latest generation clean melting quality guarantees optimum metallurgical quality and attractive welder appeal. Combined with our high basic electro slag flux FL 830 ESHC excellent results are obtained in both deposition rate as minimum delution rate due to the higher slag temperature compare to other electro slag fluxes.
