Duplex Steel UNS S31803 Anchor Bolts are Anchor Bolts that contain elements such as nickel and molybdenum along with chromium. These elements provide them with good yield strength. It also provides resistance to corrosion. They have excellent mechanical properties as well as chemical properties. Because of this, they withstand very well in higher temperature and pressure bound conditions. Duplex Steel UNS S32205 Anchor Bolts have high tensile strength. They also have the property of fabricability. These duplex and super duplex Anchor Bolts have high strength and are ductile.
The Super Duplex Steel s32750 Anchor Bolts have properties such as weldability and also have excellent finishing. They are resistant to general corrosion even at unfavourable temperature conditions. The Super Duplex Steel 32760 Anchor Bolts have properties such as great tensile strength. These are also durable. These Super Duplex Steel s32760 Anchor Bolts also have the characteristic of being weldable. They also can be fabricated easily. Also, while manufacturing these Anchor Bolts, all the necessary standards and norms are considered, so that good quality products are manufactured.
