**Super Duplex Steel S32750 bolts** are distinguished by their unique dual-phase microstructure of ferrite and austenite, which grants them **high tensile and yield strength**—up to twice that of standard stainless steels. They feature around **25% chromium, 7% nickel, and 4% molybdenum**, providing outstanding resistance to **pitting, crevice corrosion**, and **chloride stress corrosion cracking**, even in harshly saline or chemically aggressive environments. These attributes make S32750 bolts perfect for applications that demand both strength and corrosion resistance under pressure.
