Piyush Steel is the prestigious industry that is relatively involved in manufacturing and offering the wider ranges of Alloy 20 tubes. These are provided to the buyers in national and international product quality standards. These tubes are also known as UNS N08020 tubes. No doubt these tubes are having many good features to offer. This has made it be used in many industrial applications inclusive of the chemical processing industry. These tubes are developed for use mainly in the industries that are related to sulfuric acid. They are having a very good ability to resist sulfuric acid. We are globally dealing with our buyers as a manufacturer, supplier and exporter are providing the tubes to our buyers at different specifications. It thus varies in standards, dimensions, sizes, wall thickness, types, length, forms, ends, etc. Also, we are providing the same to our buyers at cut-made specifications same as per the drawings buyers have provided.

Alloy 20 details-
Alloy 20 is also called by another name carpenter 20. It is the chromium, nickel, and iron austenitic alloy that is developed for maximizing the resistance to attacks against acids particularly sulfuric acid. This is a super alloy that is having very good resistance to general corrosion, crevice corrosion and pitting in the chemical that is having sulfuric and chlorides, nitric and phosphoric acid. This alloy is too having niobium that is for the purpose of stabilization against sensitization and intergranular corrosion.
Also, the alloy combines very good corrosion resistance along with the elevated mechanical properties with fabrication ease. The alloy is designed originally for use in industries that are related to the sulfuric acid. Alloy 20 today has become a popular selection for various purposes and is used in plastic industries, chemical industries, etc.
Characteristics of tubes-
Alloy 20 tubes are having many good features to offer due to which it has become an ideal product and use in tough industrial applications and high-temperature atmospheres. The characteristics found in the product is-
• Excellent resistance to pitting, corrosion, crevice corrosion, and pitting
• Good resistance ability against acids like sulfuric acid
• Very good mechanical properties and fabricability
• Less carbide precipitation at the time of welding is assured
• Excel in corrosion resisting to hot sulfuric acids
Manufacturing of the tubes-
To bring out the commendable quality of alloy 20 tubes we are developing it by using the superior quality of alloy. The alloy that is used for making the product is thoroughly examined and checked to make sure that no poor quality of tubes development is done. Also, we as a manufacturer are making effective use of available refined technology and modern tools. Using those in a better way automatically adds strength to the product quality. The professional experts are there that are examining all the stages of production and thus guiding the workers to bring out the product of excellent quality. Quality control team efforts also have helped us in making the best quality of tubes.
