GETIG 90SB9

SOLID WIRE FOR CREEP RESISTING STEELS
IDENTIFICATION :ER 90S-B9
CLASSIFICATION : AWS/SFA 5.28: ER 90S-B9

DESCRIPTION :

A non-coppered filler wire of high purity to match creep resisting steels of type 9CrMo modified with controlled additions of niobium, vanadium & nitrogen. Deposited weld metal meets X-ray quality.

TYPICAL USES

These materials are used in components such as, headers, main steam piping and turbine rotors in power generating plant. Applications are also anticipated in oil refinery & petrochemical plant. Service temperature is normally 500-600°C, higher temperatures upto 650°C may be limited by parent HAZ properties.
