Bolts are type of fasteners that are used to connect or join objects or components in the piping systems. Bolts are available in different sizes, types, shapes and materials as per the requirements of industrial applications. Super duplex steel is one of the most commonly used material for the fabrication of all types of Bolts.
Super Duplex Steel S32750 Bolts:
Super Duplex Steel S32750 is one of the popular grade that has mixed ferrite and austenitic structure that offers enhanced mechanical strength than other stainless steel alloys. It has excellent chemical combination of higher chromium and molybdenum content that exhibit improved corrosion resistance. The balanced chemical feature of Super Duplex Steel S32750 Bolts offers higher resistive properties particularly in higher chloride containing environments. Super Duplex Steel S32750 Bolts has Lower cost compared to other grades. Due to the higher yield strength, these bolts efficiently perform in higher pressure and temperature conditions in any industrial services. These bolts are specially designed to handle any reducing and highly corrosive atmospheres. The higher nickel content in Super Duplex Steel S32750 Bolts offers higher resistance to crevice corrosion, stress corrosion cracking and general corrosion in acidic environments. These bolts offer excellent flexibility and weldability features. Super Duplex Steel S32750 Bolts are widely reliable for the applications such as, marine applications, power generation, oil and gas processing, pharmaceutical equipment and many more.
Super Duplex Steel S32760 Bolts:
The chemical composition of Super Duplex Steel S32750 and S32760 is similar however S32760 contains more amount of copper content that offers excellent resistance to non-oxidizing and acid like sulphuric and hydrochloric. Super Duplex Steel S32760 Bolts contains molybdenum, chromium and nickel with addition of nitrogen, copper and tungsten that offers higher performance even in aggressive environments. The mixed microstructure of these bolts are perfectly resistive to chloride ion stress cracking that other grades. These bolts have very good weldability and workability features. Super Duplex Steel S32760 Bolts also offers higher resistance to sour gas and sulphide stress corrosion. These bolts offer higher impact strength that make it widely suitable for the industrial applications such as seawater equipment, subsea piping systems, chemical equipment, oil and gas, heat exchangers and many more.
