Sulfuric acid is one of the most corrosive acids used across several applications. Whilst there are several stainless steel alloys present, they are just as easily corroded on exposure to acids. As a means to improve the functionality of stainless steels in sulfuric acid solutions, Alloy 20 Fasteners Manufacturers created a nickel alloy 20. Carpenter 20 or as known as nickel alloy 20 is a metal that has excellent resistance to sulfuric acid. In comparison to grade 304 stainless steel, the Astm / Asme Sb 472 Incoloy 20 Fasteners offers better resistance to both pitting and chloride ion corrosion.

But these two properties are on par with fellow austenitic stainless steel grade 316. Some of the industries that use Werkstoff Nr. 2.4660 Hex Bolts include chemical, power generation, petrochemical, as well as the plastic industry. The above mentioned industries use highly corrosive compounds to produce the end product. Especially the chemical industry, which uses several corrosive acids. The addition of copper in the alloy protects the Alloy 20 Stainless Steel Bolts from corrosion against sulfuric acid.

Though the corrosion resistance properties of this alloy are similar to grade 316, the Uns N08020 Threaded Rod is associated with its resistance to issues against stress corrosion cracking. The other industries that make use of Alloy 20 Bolts also include applications across industries that produce solvents, explosives, pharmaceuticals,  food, and beverage as well as synthetic materials.
