Alloy 20 round bars are high-performance bars designed for superior resistance to corrosion and acid attack. These bars perform well in harsh environments and across demanding industries. Preston Pipes & Alloys, a leading Alloy 20 round bar supplier, exports bars that meet precise industry needs. These bars are very strong, resistant to wear and have a long lifespan. Common applications include cement plants, shipbuilding projects, paper and pulp processing, fasteners, textile equipment, automobile parts, machinery parts, and defense applications. As it offers a perfect combination between strength, and corrosion resistance, alloy 20 bars are still a dependable option for demanding applications.
Nickel, iron, chromium, copper, molybdenum and other essential elements are present in alloy 20, which provides outstanding chemical properties. The mixture provides high corrosion resistance, particularly against acids such as sulfuric, and phosphoric. It also offers strong mechanical properties, with a tensile strength of 80,000 psi, yield strength of 35,000 psi and elongation of 30%. The material keeps its integrity under high temperatures due to its melting point of 1443°C. Alloy 20 round bar pipe suppliers provide variants like annealed, or polished bars for different operating needs, making it suitable for both structural, and high precision work.
Alloy 20 bars follow ASTM B473/ASME SB473 standards for quality and consistency. The grade B473 UNS N08020 is available in multiple forms, such as round, square, hex, flat, billet and wire. Sizes range from 15NB to 150NB, with diameters from M6 to M48 or 1/4’’ to 2’’. Cold drawn or extruded methods are used for manufacturing bars, which range in length from 100 mm to over 3000 mm. Black, rough-turned, and bright-polished are the common finishes. Bars are being supplied in cold drawn and polished or centerless-ground and polished forms with surfaces such as hot rolled pickled, or cold drawn bright to meet the needs of the application.
Strict quality checks are performed on each batch of Alloy 20 bars to ensure durability, and performance. Magnetic particle inspection, mill test certifications and third party inspection reports are among the tests. To avoid damage during transportation, bars are carefully packaged in wooden boxes, plastic bags, or bundled with steel strips. Alloy 20 round bar stock is kept ready for reliable use in any project, due to our commitment to quality, and safe delivery.
