At standard annealing heats, ASME SA240 Super Duplex 32750 Coil has a PRE number over 40. This PRE value shows the composition’s corrosion protection across different pH and chloride settings. A higher PRE number means better protection in varied conditions.

When machining Super Duplex, rigid setups and steady feed rates are advised to prevent work hardening. The material is tougher to cut than 300 series stainless, so suitable tooling should be chosen. But with the right settings, Super Duplex can be milled, turned, drilled, and tapped.

With its unmatched strength and corrosion resistance, Super Duplex 32750 works well for demanding uses across many industries:

Oil and Gas – Wellhead parts, Christmas trees, manifolds, valves
Desalination – Reverse osmosis pressure vessels, heat exchangers, piping
Marine – Propeller shafts, pumps, valves, fasteners
Chemical Processing – Tanks, pressure vessels, scrubbers, heat exchangers
Pulp and Paper – Digesters, evaporators, storage tanks

The better performance does cost more than 300 series stainless steel. But for critical parts where strength and corrosion protection are essential, the extra cost is justified by the longer service life and reliability. The corrosion protection reduces maintenance needs and lowers overall lifetime cost.
