SOLID CORROSION-RESISTANCE CHROMIUM-NICKEL-MANGANESE WIRE FOR SAW OF AUSTENITIC 18% Cr, 8% Ni, 6% Mn TYPE STEELS AND THERMO HARDENED STEELS. HORDA 307Si has general corrosion resistance similar to that of the corresponding parent metal. The high silicon content improves the welding properties such as wetting and weld formation. It can be used in combination with fluxes AB, AF, FB types (EN ISO 14174) class 2
