Alloy 20 Pipes are high-performance austenitic stainless steel pipes designed for applications that demand excellent corrosion resistance. These pipes provide a strong and long-lasting combination as it consist of a blend of nickel, iron, chromium, copper, and molybdenum. Known for their superior composition and mechanical properties, they work well in harsh environments where standard stainless steel fails. Preston Pipes& Alloys is a leading manufacturer and supplier of Alloy 20 Pipes, delivering quality pipes that meet global standards. The material shows impressive mechanical strength with a density of 8.1 g/cm³, a melting range of 1443°C, yield stress of 241 MPa, and tensile strength of 551 MPa. These features make Alloy 20 ideal for use in both high-stress and corrosive conditions.


Alloy 20 Pipes perform well in environments that include chlorides, and strong acids. Alloy pipes offer strong resistance to pitting, crevice corrosion, and general corrosion, making them a smart choice for chemical processing, petrochemical units, pharmaceutical setups, and food and beverage plants. This alloy handles sulfuric, nitric, and phosphoric acids with ease. Because of this, Alloy 20 Pipe suppliers often recommend them for systems exposed to aggressive media over long periods. Their strong build and corrosion resistance help reduce maintenance and downtime.


Alloy 20 Pipe

The alloy 20 pipe specification includes ASTM B729, B464, and B468, with corresponding ASME codes. These pipes are available from ½”NB to 24”NB in SCH 10 to SCH XXS. OD ranges from 1mm to 254mm with wall thickness up to 20mm. They come in different forms such as round, square, hydraulic, oval, and rectangular. Length options include single, double, or custom-cut. Buyers can choose ends like plain, beveled, or threaded. Pipes are manufactured as seamless, ERW, welded or fabricated versions. For detailed options and alloy 20 pipe price list, contact the supplier for the latest information based on size and form.


Alloy 20 Pipe inventory is subject to rigorous quality checks, such as third-party inspection and mill test certificates, for complete traceability and specifications compliance. Pipes are tested for strength, durability, and resistance prior to dispatch. Safe industry standards are followed for packaging, pipes are fitted into wooden boxes, strapped with steel strips, or wrapped in plastic bags depending on customer requirements. Opt for strong, tested materials packed safely for extended performance.
