SOLID WIRE ALLOYED WITH MOLYBDENUM FOR IMPROVED PROPERTIES
IDENTIFICATION
GM 70SA1, ER 70S-A1
CLASSIFICATION
AWS A-5.28: ER 70S-A1
DESCRIPTION
• GM 70SA1 copper coated filler wire for welding 0.5% Mo steels used for creep resisting service at temperatures up to about 500ºC.
• This wire is copper coated to suppress corrosion but possible deterioration is minimised by storage at <60% RH and >18ºC.
