The Mumbai, India-based Fasteners Mart is a prominent distributor of a wide variety of high-quality industrial fasteners for many industries, including oil and gas, marine, chemical, and construction. Among its popular products is the Super Duplex Steel Nuts S32750. Manufactured from high-strength Super Duplex Steel, its nuts are available in grade 2507, which are highly resistant to corrosion and possess enhanced mechanical properties. They come in different shapes, such as hexagonal and heavy-duty flange, so they are well-suited for application in harsh and high-stress environments.
Super Duplex Steel Nuts S32750 contain 25-30% chromium, 4-6% molybdenum, and 6-8% nickel. The above composition provides good pitting, crevice, and stress corrosion cracking resistance. The nuts have a tensile strength of 800 MPa to 1,200 MPa and a yield strength of 550 MPa to 800 MPa. They are extremely corrosion-resistant in the presence of chloride, hence their application in offshore and chemical processing industries. They retain their mechanical properties even in high-temperature conditions, guaranteeing durability and reliability.
