Oerlikon Inertrod 310 description: INERTROD 310 is a W 25 20/ER 310 solid TIG welding rod depositing a C-25Cr 20Ni weld metal. Suitable for use mainly with Ar shielding gas. INERTROD 310 weld metal has high temperature ductility and excellent resistance to oxidation at working temperatures <1000C. It is used for the welding of 310 austenitic stainless steel pipe, plate and fittings used in the fabrication of furnaces and similar applications working at elevated temperatures. It is used mainly for heat exchangers and hot water boilers. INERTROD 310 weld deposit is fully austenitic. TIG rod for welding type AISI 310 or the like totally austenitic stainless steels. The totally austenitic deposit guarantees excellent high temperature corrosion resistance.
