Hex Forge Inc. is a manufacturer of Duplex Steel Nut in different sizes. We supply and export excellent quality fasteners to clients all over the world. Nuts are available in various finishes, including surface finish, end finish, dimensions, forms, sizes, length, and hardness. The nuts can also be custom cut to the client’s needs.
These duplex steel s32205 hex nuts contain a variety of metals that distinguish them from other alloys. This grade, which has excellent mechanical strength, is extensively utilized in diverse industrial applications. Precisely, this grade resists chloride pitting corrosion, stress corrosion cracking, and crevice corrosion. Chromium is 22 percent, molybdenum is 3%, and nickel is 5-6 percent in duplex steel s31803 heavy hex nuts. This grade also has properties that make it appropriate for industrial use. Duplex steel is a ferrous, nickel, and chromium-based alloy with an austenitic microstructure and may be used at room temperature. The alloy used generally has a blend of austenitic and ferrite phases. Duplex steel S32205 heavy hex nuts have a high hardness and excellent weldability. High resistance to corrosion fatigue, good workability, solid construction, weldability, low maintenance, and cost-effectiveness are just a few of the benefits of our Duplex S32205 Hex Nut. We manufacture entirely acceptable products using innovative technologies and modern machines. Our duplex steel s31803 lock nuts are designed to withstand high temperatures and corrosive situations. At temperatures as high as 475 degrees Celsius, aging exposed for an extended period can cause corrosion resistance to deterioration and embrittlement.
Short-term aging at temperatures up to 475 degrees Celsius is a heat treatment that enhances corrosion resistance. Other properties, on the other hand, may deteriorate. The testing is carried out in stages, including material and strength tests. The exams are carried out under expert supervision. Some of the tests carried out by technical experts are hydro testing, hardness testing, mechanical properties testing, tensile testing, destructive/non-destructive testing, micro and macro testing, and pitting corrosion testing.
