Oerlikon Carborod CrMo2 description: CARBOROD CrMo2 is a copper coated WCrMo2Si/ER90S-G type solid TIG welding rod depositing a 2 1/4Cr 1Mo weld metal for the welding of creep resistant steels. Suitable for use with Ar shielding gas. CARBOROD CrMo2 is used for welding of similar composition and 1/2Mo 1/4V and 1%Cr 1Mo steels. Used in the construction of steam generating plant operating at temperatures <600C. Also suitable for the welding of 1¼Cr 1Mo steels where improved resistance to hydrogen attack or corrosion by sulphur is required. Main applications include the welding of boilers, plates and tubes as well as in oil refineries e.g. in crack plants produced from mainly 10CrMo9-10 (ASTM A335 Gr. P/T22).
