Home / Alloy 20 Products / Alloy 20 Forged Fittings
Eckhardt Steel & Alloys is one of the well-known suppliers of Alloy 20 Forged Fittings, which has excellent mechanical properties and fabricability. Alloy 20 Forged Threaded Fittings is a nickel-iron-chromium alloy which has the addition of copper content and molybdenum content. Alloy 20 Forged Socket Weld Fittings has perfect for use around phosphoric, nitric, and sulfuric acids. Most welding methods can be used when working with Alloy 20 Forged Threaded Tee, except for oxyacetylene welding. Alloy 20 Forged Socket Weld Elbow is a solution for stress corrosion cracking that can occur when stainless steel is introduced to chloride solutions. Our Alloy 20 Forged Threaded Cross is an austenitic stainless steel which was designed for maximum resistance to acid attacks. These Alloy 20 Forged Socket Weld Cap has excellent general corrosion resistance to sulfuric acid and to chloride stress corrosion cracking.
Our Alloy 20 Forged Threaded Bend resists pitting and chloride ion corrosion, better than Alloy 304 and on par with Alloy 316L. Annealing of these Alloy 20 Forged Socket Weld Coupling should be between 1725 °F and 1850 °F for 30 minutes at temperature per inch of thickness. Our Alloy 20 Forged Threaded Union is a low-carbon, niobium-stabilized austenitic nickel / iron / chromium alloy with additions of contents like copper and molybdenum. These Alloy 20 Forged Socket Weld Bushing was developed specifically for hot sulphuric acid applications.
Alloy 20 forged fittings handle environments that most standard materials cannot withstand. The alloy carries copper, niobium, molybdenum, and nickel in a composition engineered specifically to resist sulfuric acid attack, something stainless steel grades struggle with at concentrations above 20%. Registered under UNS N08020, this material sustains performance across chloride-heavy media, oxidising acids and aggressive chemical environments where pitting and stress corrosion cracking surpass most alternatives. ASTM B462 alloy 20 forged fittings meet the dimensional and mechanical requirements that chemical-duty piping systems demand. Sectors including chemical processing, pharmaceutical manufacturing, petrochemical refining, and food processing all specify this alloy, where process media would degrade 316L or Duplex fittings within months. When corrosion allowance is insufficient, the appropriate material specification becomes essential.
Eckhardt Steel & Alloys supplies a full range of forged fitting geometries in Alloy 20, covering Alloy 20 Elbows, Alloy 20 Tees, Alloy 20 Couplings, Alloy 20 Unions, Alloy 20 Caps, Alloy 20 Bushings, Alloy 20 Plugs, and Alloy 20 Crosses. Both threaded and socket-weld fittings are available, manufactured to ASTM B462 and dimensionally compliant with ASME B16.11. Pressure classes span 2000, 3000, 6000, and 9000, covering low-pressure utility lines through high-pressure reactor piping. Each fitting holds tight dimensional tolerances to ensure leak-proof assembly without rework at the site. Forging refines the grain structure through the full cross-section, producing mechanical strength that cast equivalents cannot match. For systems where a single joint failure means a process shutdown, that structural consistency matters far more than price-per-piece
Eckhardt Steel & Alloys, founded in 2004 and ISO-certified, operates from Mumbai with a decade-long track record across nickel alloy and stainless steel supply.

They resist sulfuric acid, chlorides, and phosphoric acid far better than 316L, making them reliable in corrosive chemical service above 60°C.
Both types are available under ASME B16.11 in Class 2000, 3000, 6000 and 9000 from stock.
Non-standard sizes, special bore dimensions and modified end connections are machined against customer-supplied drawings and specifications.
The UNS N08020 composition prevents intergranular corrosion in sulfuric acid service, reducing maintenance cycles and unplanned shutdowns significantly.
