Duplex Steel Nut/Bolts Supplier

The alloy used to make Duplex Steel Nut and Bolts has a high chromium content and a low to moderate nickel content. These nuts and bolts have a high tensile strength in addition to increased hardness and toughness due to the high chromium content. Duplex Steel Nuts and Bolts contain molybdenum, which prevents fatigue corrosion. They also contain trace amounts of carbon, which aid in preventing stress corrosion cracking. The mixed-yet-balanced austenite and ferrite microstructure of the alloy is another factor that contributes to the good mechanical properties of the duplex steel bolts.

These Nuts and Bolts are produced from a special grade of duplex steel. We also produce Inconel Nuts and Bolts, Hastelloy Nuts and Bolts, And Monel Nuts and Bolts.

These Duplex Steel Nuts and Bolts are also resistant to crevice corrosion, stress corrosion cracking, and pitting corrosion. They are suitable for use at elevated temperatures and are also easy to weld. These nuts can be used in a variety of industrial applications. Duplex Steel Nuts and Bolts are hence less prone to be damaged, deformed, or dented. These duplex nuts and bolts also have a low coefficient of thermal expansion. This means that they may reduce weight.

The tensile strength of Duplex Steel Bolts and Nuts is twice as high as that of austenitic or ferritic stainless steel. In addition, duplex stainless steels have good toughness at low temperatures. They are used for a wide variety of applications in industries like oil and gas extraction. They are also used in transportation. Duplex stainless steels are more cost-effective than standard stainless steels. However, duplex stainless steels are more difficult to form.
