Description:
SS-307 gives full austenite structure containing 4-5% Mn. Weld metal is highly resistant to impact, wearing and hot cracking. It is suitable for forming a buffer layer for hardfacing and joining of armour steel plates that are low hardenable and work-hardening austentic Mn steels. It can also be used for dissmilar joining C-Mn steels with austentic and ferritic stainless stells.
Applications:
Typical applications include stainless steel piping in refineneries and chemical plants.
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.
