Description :
SS-307HM gives a full nonmagnetic austenite structure containing 6% Mn. Weld metalis highly resistant to impact , wearing. and hot cracking. It is especially suitable for military usage , such as mine sweepers. Preheating or postweld heat treatment is not required.
Applications :
It can be use for 18% Cr-8%Ni stainless steel, 14% Mn steel, the steels with poor weldability and buffer layer welding.
Note On Usage :
1. Rebake the electrodes at 200°C for 1 hour and keep it at 100°C prior to use.
2. Use stainless steel wire brush for cleaning of slags.
3. Follow the recommended welding parameters to achieve good sound welds.
