What is the difference between UNS S32750 and S32760?

S32760 Super Duplex Stainless Steel

While involving extended exposure to temperatures more than 572F use of S32760 is not recommended. The chemical composition of S32750 and S32760 are similar; however, the latter contains slightly more copper and tungsten.

Applications

Duplex stainless steels are extremely corrosion resistant, work hardenable alloys. Their microstructures consist of a mixture of austenite and ferrite phases. As a result, duplex stainless steels display properties characteristic of both austenitic and ferritic stainless steels. This combination of properties can mean some compromise when compared with pure austenitic and pure ferritic grades.

• Duplex stainless steels are typically used in:
• Chemical processing, transport and storage
• Oil and gas exploration and offshore rigs
• Oil and gas refining
• Marine environments
• Pollution control equipment
• Pulp & paper manufacturing
• Chemical process plant
