Alpha Nickel

Alloy 20 Fasteners Manufacturer, Supplier In Mumbai India

Alpha Overseas is one of the known suppliers and manufacturers of Alloy 20 Fasteners. These austenitic alloys, like Alloy 20, have an iron base and exhibit good corrosion resistance to various media. They are used in multiple processes, including flue-gas desulfurization, chemical processing, food processing and storage, and pharmaceutical applications, to mention a few. A nickel-iron-chromium austenitic alloy called Alloy 20, called Carpenter 20 Fasteners, was created for the most significant resistance to acid assault, particularly sulfuric acid. It was made specifically to withstand sulfuric acid and is known as UNS N08020 Fasteners. Its amounts of copper, molybdenum, nickel, and chromium offer outstanding general corrosion resistance. Columbium is also used to stabilize it to reduce carbide precipitation during welding. We provide Alloy 20Cb3 Fasteners as a remedy for the stress corrosion cracking that may develop when chloride solutions are exposed to stainless steel.

It can be manufactured quickly and has good mechanical qualities. Alloy 20 has a 33% nickel content and is essentially immune to chloride stress corrosion cracking. Alloy 20 Steel, famous in the process industry, is available in a wide range from Alpha Overseas' broad inventory. We specialize in completing orders quickly, and most of our in-stock items are available for worldwide shipment on the same day.

With a minimum tensile strength of 80ksi and a minimum yield strength of 35ksi, Alloy 20 Screws are robust. The material has a 217HBW hardness rating, which is high. The stud protrusion on the Alloy 20 Stainless Steel Stud Bolts is used to join two components together. The size of the fasteners ranges from 14 inches to 1 12 inches. One of the most popular nuts is the alloy 20 hex nut because it has an exceptional grip for loosening and tightening.

Additionally, there are threaded rods. Without using a screw head or bolt, two items can be connected using an Alloy 20 Threaded Rod. Threads may be present on both ends or only one end of the threaded rods. As a fastener provider, we offer various varieties, including the Alloy 20 N08020 Washer. The washers in systems with large loads are crucial for bridging gaps and absorbing stress and vibration.
