Purpose
- Fast-freezing rutile flux-cored wire, same CrNiMn 307 family — work-hardening austenitic deposit, for dissimilar-metal joining and buffer layers on 14% Mn steel.
Why it works
Same principle as the INX 307 electrode family, in gas-shielded flux-cored form — higher deposition rate, useful for joints of unknown steel type, armor plate and buffer layers over 14% Mn austenitic steel.
Fields of application
- Joining of dissimilar metals, welding of unknown steel types, armor steels.
- Buffer layer over 14% Mn austenitic steel before hardfacing.

Advantages
- Service range -120°C to +300°C.
Limitations
- The deposit work-hardens due to its manganese content (6%) — machine before it hardens.
