OK Autrod 16.51
GMAW

A stainless 24% Cr, 13% Ni (''ER309LSi'') electrode for the GMAW of similar alloys in wrought and cast forms. Also used for ordinary 18Cr8Ni steels where there are severe corrosion conditions. Specially recommended for joining dissimilar steels such as 18Cr8Ni steels to mild steels. OK Autrod 16.51 is usually welded with Ar/(1-3%)O2 as the shielding gas.
