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.
