CHARACTERSTICS
RASI 307R-16 is a versatile austenitic Stainless Steel electrode with
19Cr-9Ni-6Mn. It has a high deposition efficency. The weld Metal is
characterised by exceptional crack resistance and high deformability. The
stable austenitic microstructure does not suffer any sigma phase formation.
Weld metal tends to work Harden through deformation by impact and there by
gains considerable abrasion resistance. |

SUGGESTED WELDING PROCEDURE
Re-dry the Electrode at125oC for 1Hr, use short arc during welding, keep the
electrode in dry conditions, do not keep excesive current and remove the
slag with SS wire brush. |
