Specifications:
- AWS: A5.28: ER 90 SB-9
DESCRIPTION AND APPLICATION
- TIG 90S-B9 is a 9Cr-1Mo solid wire modified with niobium (columbium) and vanadium designed to provide strength, toughness, fatigue life, oxidation resistance and corrosion resistance at elevated temperatures.
- Due to the higher elevated temperature properties of ER90S-B9, components that are now fabricated from stainless and ferritic steels may be fabricated from a single alloy, eliminating the problems associated with dissimilar welds.
