What is the Difference Between Open Die and Close Die Forging of Super Duplex Steel F53 Flanges?
Open Die Forging
- shapes metal in open space
- can create large parts
- produce parts with custom shapes
Close Die Forging
- uses molds under high pressures
- best for small parts
- limited to the mold’s dimensions
