Alloy 20 Fasteners

Super Piping Solution Inc specializing in pipe fabrication and a wide range of materials and processes. We process skid assemblies in wide range of our products.

Alloy 20 Fasteners are blessed by good mechanical properties. Moreover, due to their properties, they are also known as Carpenter 20 Fasteners. However, they are developed by carpenter technology.The product was specifically designed to withstand sulphuric acid. Excellent corrosion resistance is provided by its nickel, chromium and copper levels. Stress- free cracking is possible only because of Alloy 20 fasteners.

Alloy 20 works well with all other acids but it was specifically designed to withstand the environment of hot sulphuric acid.The product also highlights suitable resistance in nitric and phosphoric acids. Alloy 20 Fasteners are cost- effective as compared to higher nickel-based alloys. Alloy 20 Bolts, Alloy 20 Studs, and Alloy20 Socket Cap Screw are some common types of Alloy 20 Fasteners. For moderately corrosive applications fasteners can be made in any style.

Alloy 20 Fasteners are an important application in pharmaceutical applications, food processing, chemical processing, as well as flue-gas desulfurization. Alloy 20 Fasteners are often used in industries like food production, chemical process piping, and bubble caps, etc.

Alloy 20 Fasteners against different working environments offer a natural resistant. However,Alloy 20 Fasteners are a stainless steel fastener which is the biggest advantage of Alloy 20. Moreover, they are developed for maximum resistance to sulphuric acids. In hot sulphuric acid Alloy 20 Fasteners provides a good performance. They are good resistance to nitric and phosphoric acid. The product can easily be fabricated hence its mechanical properties are good enough. Fasteners are an iron base piping components which are suitable for the use in food processing and chemical processing.

With the ability to maintain their strength, Alloy 20 Fasteners works well at high temperatures. Specification guide, materials test certificate and welding guide are attached with the product for customer satisfaction. Standard industrial packing is done to protect products from any damage. Moreover, packing is done in cartons, wooden cases, and pallets with end cap support.
