Oerlikon Inertrod 308L description: INERTROD 308L is a W 19 9 L/ER 308L type solid TIG welding rod depositing a low C-19Cr 9 Ni weld metal. Suitable for use mainly with Ar shielding gas. INERTROD 308L is used for the welding of 304 and 304L grade stainless steel. The weld metal has good corrosion resistance properties, including intergranular attack from a range of liquid media at service temperatures <300C. It is used for a wide range of applications including pipework and plate fabrication, vessel production etc. Batch with controlled low ferrite number is available for cryogenic applications. Low carbon reduces the propensity to intergranular carbide precipitation, which increases the resistance to intergranular corrosion without the use of stabilizers. TIG rod for welding type AISI 304 and 308 austenitic stainless steels. Excellent mechanical strength and corrosion resistance.
