Industries that deal with corrosive environments need materials that don't break down or lose their value in such tough conditions. Duplex Fasteners manufacturers produce critical connection components containing balanced microstructures of austenitic and ferritic phases. This singular composition results in that the product is highly resistant to chloride stress corrosion cracking, at the same time, it is kept the mechanical strength to the highest. Those fasteners are used in underwater shipbuilding, chemical processing equipment, and oil rigs located in the sea areas that are contaminated with pollutants where ordinary stainless steel may run out of service way too quickly.
[b]Manufacturing Considerations and Quality Standards[/b]
The making of duplex fasteners is a very delicate task involving a lot of precision in controlling the chemical make-up and the heat treatment processes to end up with the best phase balance. The usual grades are 2205 (F51) and 2507 (F53) that differ from one another in the content of chromium, molybdenum and nitrogen. Quality assurance is carried out through tests, such as material identification, ferrite testing, and pseudo mechanical property validation, in other words, they are done to confirm satisfaction to ASTM F738M and other implicated standards.
[b]Performance Benefits in Specialized Applications[/b]
Monel alloys as well as duplex fasteners are the two pieces of equipment that do not falter under harsh conditions. The use of duplex grades is made by most of the researchers as a comparison, because they possess almost twice the yield strength of the austenitic stainless steel. At the same time they are able to provide better pitting and crevice corrosion resistance. Thanks to those properties, these fasteners are now widely used in the construction of the seawater industry, chemical plants, and facilities of pulp and paper.
[b]Material Selection for Aggressive Environments[/b]
Material selection is a vital step in the design of equipment that will operate under corrosive conditions severe. The choice of material for operations that involve hydrofluoric acid, reducing environments, or marine atmospheres, Monel 400 Plate is a perfect solution that offers corrosion resistance as the nickel-copper composition gives stable performance in the areas where other alloys become quickly degraded.
