Duplex Steel UNS s33750 is the most highly used grade in the steel industry. This grade has some extraordinary properties, which are one of the main reasons for its application in high as well as low temperatures. Duplex Steel UNS s33750 has high thermal conductivity with low carbon content, and low carbon content avoids carbide precipitation which commonly occurs because of welding and forging. 

The grade is highly efficient and effective for high-temperature applications. 


Duplex Steel UNS s32750 provides high protection from various chemical and physical procedures. Duplex Steel UNS s32750 also protects from erosion, reduction, and rusting; it resists corrosion, crevice corrosion, and stress cracking. 

The grade also provides excellent protection from oxidation and chloride mixed environments. Duplex Steel UNS s32750 has a mixed microstructure of austenitic and ferrite.

We at Calico Metal Alloys manufacture these grades into various pieces of equipment. These pieces of equipment are manufactured for multiple industrial and commercial uses. These strong duplex steel grades combine high strength and moldability, which is one of the essential features of the application. 

Chemical composition:

The chemical composition of Duplex steel UNS s32750 includes elements like chromium, molybdenum, nickel, silicon, nitrogen, copper, sulphur, iron, and phosphorus. These elements are known for providing excellent stability, strength, and durability to the grade. These pipes are highly welded and it also support pitting and forging. 

Duplex steel UNS s32750 provides excellent resistance from corrosion, crevice corrosion and stress cracking.
