DETAILS
It gives an austenitic filler metal of the Cr-Ni type that is high (6%) in Mn content.
Features
- Weld beads are highly resistant to oxidation at operating temperatures up to 850°C and also to acids.
- AS P-308Mn can be used for welding hardenable steels (alloyed or unalloyed), Mn steels, armour plates, rail steels, stainless chromium steels, tool steels and steels with poor weldability.
- Building up of parts operating under impact, high pressure and cavitation; surface build up of water turbine vanes; build up of valve seats and joining and building up of rail switches are among its usage areas. AS P- 308 Mn can also be used for forming buffer layer passes before hardfacing applications having a chromium carbide structure.
- The lowest possible welding current should be selected to avoid the overheating of the electrode during welding. For hard Mn steels, weld beads should be forged
