NSS-307

Specification

AWS Specification: AWS A5.4 E307-16
JIS Specification: N/A
Other Specification: N/A

Description

NSS-307 is a lime-titania stainless steel electrode that forms the deposited metal of 9%-19% Ni - 5% Mn stainless steel with the perfect austenitic structure
Deposited metal has excellent crack resistibility and shows easy work hardening

Application

Welding of 14% Mn steel, steel armour, hardenable steel, and generally all hard-to-weld steels
Joining of wear plates to each other
Joining of stainless steels to carbon steels
Building up of rails and buttering layers before hardfacing on 14%Mn steel, steels of unknown composition, or on carbon steels
Extensively used in steelmaking public works, mining, carrying, and dredging

Remarks

Remove dirt, such as oil and dust from the groove

Keep the welding current as low as possible

Keep the arc length as short as possible

Re-bake the electrode at 200-250�C for about one hour before use
