S32750

Characteristics

S32750 is a super duplex stainless steel designed for use in corrosive environments that require high strength. Because of its high content of molybdenum (Mo), chromium (Cr), and nitrogen (N), the material is highly resistant to pitting and crevice corrosion. It is also resistant to chloride-induced stress-corrosion cracking, erosion corrosion, corrosion fatigue, and general corrosions in acids.
