Description:
Superduplex stainless steel S32750 has a very high resistance to localized corrosion in chloride media, combined with a high mechanical strength. It is also with a pitting resistance equivalent number, PREN, above 40, and a minimum guaranteed yield strength of 550 MPa, allowing for leaner design in load bearing applications. The alloy composition, including molybdenum and nitrogen additions, has been optimized to obtain a 50/50 austenoferritic microstructure with outstanding corrosion resistance. The material provides cost - efficient alternatives for a wide range of applications, including offshore, phosphoric and sulfuric acid production as well as flue gas cleaning.
