Alloy 20 Screws Supplier

Alloy 20 is a highly corrosion-resistant material often used in applications with strong acids and other corrosive chemicals. Alloy 20 screws are screws made from this material and are commonly used in industries such as chemical processing, food processing, and pharmaceutical manufacturing.

The high corrosion resistance of Alloy 20 screws is due to the composition of the material, which includes nickel, chromium, molybdenum, and copper. These elements resist sulfuric acid, phosphoric acid, and other harsh chemicals

Incoloy 20 Screw come in various sizes and configurations to suit various applications. They are often used with other Alloy 20 components, such as pipes, fittings & flanges, to create a complete corrosion-resistant system. Alloy 20 screws are a reliable and durable solution for corrosive chemical resistance applications. At Neelkamal Alloys LLP, we offer a variety of high-quality Alloy Products, including Alloy 20 Washers, Alloy 20 Nuts and more.

UNS N08020 Screw have several notable features that make them an ideal choice for applications requiring corrosive chemical resistance. They have high corrosion resistance due to their composition of nickel, chromium, molybdenum, and copper. This composition makes 2.4660 Screws particularly resistant to sulfuric acid, phosphoric acid & other harsh chemicals, making them suitable for chemical processing, food processing, and pharmaceutical manufacturing. We offer a wide range of products, including Nickel Alloy 201 Sheets ,Super Duplex Steel 2507 Fasteners, & many more.

Inconel 20 Screws have good mechanical properties, including high strength and hardness. They also have good flexibility and toughness, which means they can withstand impact and vibrations without deforming or breaking. This makes them a reliable & durable choice in harsh environments where other materials may fail. Incoloy Alloy 20 Screws are easy to work with and can be machined, welded & formed to suit various applications. This versatility makes them suitable for various industries, including oil and gas, marine & aerospace.
