Cromatig 316LSi is a TIG welding wire intended for welding low-carbon 18% Cr / 8% Ni/Mo type acid-resistant steels (AISI 316L, Polarit 750, Polarit 752, SS 2343 and similar). It is also suitable for welding niobium- and titanium-stabilized grades 321 and 347, for applications below 350 ⁰C. Thanks to the increased silicon content, the welding properties are particularly good.
