These Duplex & SUPER DUPLEX Steel Washers have resistance towards corrosion. These are also known for their yield strength. The Duplex Steel UNS S31803 Washers contain nickel and molybdenum, along with chromium in their chemical composition. These provide them with excellent yield strength. Along with yield strength, they also make them resistant to corrosion.
The Duplex Steel UNS S32205 Washers have properties such as great tensile strength. Along with this, they also have the characteristic of fabricability. As they are corrosion resistant, they are used in applications where the environment may be unfavorable. Also, these are ductile and also have dimensional accuracy.
The Super Duplex Steel s32750 Washers also have excellent finishing and longer life. The Super Duplex Steel s32760 Washers also have the property of fabrication. They also have the property of ductility and are also weldable. These have other mechanical properties as well and are also durable.
