Oerlikon Carborod CrMo5 description: CARBOROD CrMo5 is a copper coated WCrMo5Si/ER 80S-B6 type solid TIG welding rod depositing a nominal C-0.3Mn5.6Cr0.6Mo low alloy steel weld metal. Suitable for use with Ar shielding gas. CARBOROD CrMo5 is used for welding elevated temperature creep resisting steels of similar composition (P/T5) as used in the power generation and petrochemical industries where corrosion resistance to steam, hot hydrogen gas and high sulphur crude oils is a requirement. TIG rod for welding 5% Cr and 0.5% Mo steels that resist hot creep. Used in the chemical industry and in ammonia synthesis processes.
