What Are Super Duplex Steel UNS S32750 Sheets?

Super Duplex Steel UNS S32750 Sheets are corrosion-resistant sheets manufactured with an advanced alloyed stainless steel. Boasting exceptional strength and durability, these corrosion resistant sheets make ideal use in harsh environments such as offshore oil rig platforms, chemical processing facilities, marine applications and offshore oil and gas platforms. With both austenitic and ferritic microstructures present on each sheet ensure optimal mechanical properties and resistance against chloride-induced corrosion as compared to standard stainless steels.

Manufacturing Process Of Super Duplex S32750 Sheets

Reheating Furnace

Reheating furnaces are used in hot rolling mills to heat the steel stock to the rolling temperatures.

Scale Breaker

Slab moves first through a scale breaker, which is a two-high rolling mill with vertical rolls that loosens the furnace scale and removes it with high-pressure water jets.

Finish Rolling

The last stage of the rolling process is cold rolling,


Cooling or Quenching is a process of cooling a metal at a rapid rate.

Skin Pass Mill

This produces high-gloss surfaces and achieves the desired mechanical strip properties such as deep-drawing strength.

Marking & Packing

Proper packaging and labeling not only makes the final product look attractive but also save a huge amount of money by saving the product from wrong handling.
