Oerlikon Inertrod 307 description: INERTROD 307 is a W 18 8 Mn/ER 307 (similar) type solid TlG welding rod depositing a C-18Cr8Ni6Mn weld metal. Suitable for use mainly with Ar shielding gas. INERTROD 307 is suitable for welding dissimilar steels between unalloyed and austenitic stainless steels or heat resisting steels, also used for the welding of hardening and tempering steels, e.g. ballistic steels. The increased silicon content promotes weld pool fluidity resulting in a smoother weld deposit.
Stainless steel rod for welding dissimilar steels, hardening and tempering steels, armored, bullet-proof and 13% Mn steels.
