Alloy 20 washers are incredibly versatile & highly functional in various applications. With the ability to resist corrosion from harsh environments, these washers are widely used in chemical processing, food processing & pharmaceuticals.

Alloy 20 is a highly durable and austenitic material of 20% chromium, 3% molybdenum, and 35% nickel. It’s highly resistant to corrosion in acids like sulfuric, hydrofluoric & phosphoric, making it a perfect solution for industries that rely on harsh chemicals. The washers made of alloy 20 are precision-engineered with exact dimensions to fit various applications.

Alloy 20 is a highly corrosion-resistant material commonly used in applications requiring resistance to acidic environments. Alloy 20cb3 Washer therefore, possess excellent resistance to corrosion from a wide range of acids, such as sulfuric, phosphoric, and nitric acid. These washers also resist stress-corrosion cracking, pitting, and crevice corrosion, making them a reliable choice in harsh environments.

Alloy 20 Washers are commonly used in the chemical processing industry, where they are employed in various components such as heat exchangers, tanks, and piping systems. They are also used in the pharmaceutical, food processing & petrochemical industries.

Another important feature of ASME B18.22.1 Washers is their high mechanical strength, which makes them resistant to deformation and breakage under heavy loads. This property makes UNS N08020 Washers ideal for applications requiring high tensile strength & durability. Alloy 20 washers are an excellent choice for applications that require corrosion resistance, mechanical strength, and durability. Their properties make them reliable in harsh and corrosive environments, providing long-term performance & cost-effectiveness.

Incoloy 20 Washer offer several benefits, making them an ideal choice for various industrial applications. One of the main advantages of Alloy 20 washers is their exceptional corrosion resistance. They are highly resistant to various acidic environments, including those containing sulfuric, phosphoric, and nitric acids.
