Postalloy® 2996-SA

Postalloy® 2996-SA is a non-cracking medium chrome welding wire for submerged-arc welding. Deposit polishes in service to reduce friction and minimize wear of mating part. Provides a medium hard martensitic steel deposit with good corrosion resistance, as well as metal-to-metal wear and abrasion resistance. Multiple layers can be applied crack-free. For use on carbon and alloy steels.
