Super Duplex Steel S32750 Bolts are made up of about 25% chromium, 7% nickel, and 3.6% molybdenum, along with some nitrogen and manganese. This high-alloy duplex stainless steel features a blend of ferritic and austenitic phases, providing remarkable strength and corrosion resistance. Typically, these bolts boast a tensile strength of 800 MPa and a yield strength of 550 MPa, along with impressive impact toughness even in low temperatures. The alloy’s PREN (Pitting Resistance Equivalent Number) surpasses 40, which means it’s highly resistant to pitting and crevice corrosion in harsh environments like seawater and acidic solutions.
