Forgings are made by forcing materials into customized shapes either by the force of a falling ram upon an anvil or by a die press enclosing a piece of metal and squeeze-forming the part. Forging is a manufacturing process involving the shaping of metal using localized compressive forces.

The corrosion resistance property of the alloy is credited to the addition of both Molybdenum and nickel.
