Alloy 20 Sheet Supplier in Mumbai | Alloy 20 Plate and Coil

When industries demand superior corrosion resistance and mechanical strength, Alloy 20 Sheet, Plate, and Coil emerge as the most dependable solutions. Alloy 20, also known as Carpenter 20, is a nickel-iron-chromium-based superalloy designed to resist sulfuric acid and other aggressive chemicals. Its excellent resistance to pitting, crevice corrosion, and intergranular attack makes it ideal for chemical, petrochemical, pharmaceutical, and food processing industries. The Alloy 20 Sheet is widely used in tanks, heat exchangers, pumps, and valves where exposure to acidic environments is unavoidable. Meanwhile, the Alloy 20 Plate offers superior strength and weldability, ensuring durability even under high temperature and pressure conditions. The Alloy 20 Coil adds flexibility for fabrication, allowing easy forming and rolling into complex designs for equipment manufacturing. Together, these products deliver unmatched performance where standard stainless steels fall short, making Alloy 20 the material of choice for critical operations.
What sets Alloy 20 Sheet, Plate, and Coil apart is their balanced chemical composition of nickel, chromium, molybdenum, and copper—providing exceptional resistance to acids such as nitric, phosphoric, and sulfuric acid. This makes Alloy 20 one of the most versatile corrosion-resistant materials available today. The Alloy 20 Sheet ensures a smooth surface finish and dimensional accuracy, suitable for lining and cladding pressure vessels and reactors. The Alloy 20 Plate is extensively used in flue-gas scrubbers, pickling tanks, and marine components due to its outstanding oxidation resistance and mechanical integrity. On the other hand, the Alloy 20 Coil is preferred for applications that demand flexibility and easy fabrication, including tubing, heat exchanger plates, and condenser parts. Industries that rely on high-purity processing—such as pharmaceuticals, pulp and paper, and food production—trust Alloy 20 for its hygiene-friendly and non-contaminating characteristics. Its superior performance under both oxidizing and reducing conditions ensures reliability, safety, and long-term cost savings.
Our Alloy 20 Sheet, Plate, and Coil are manufactured with strict adherence to ASTM, ASME, and other international quality standards. Each product undergoes rigorous testing, including ultrasonic inspection, PMI (Positive Material Identification), mechanical strength analysis, and corrosion testing, ensuring reliability and consistency in every batch. We supply Alloy 20 products in a range of sizes, finishes, and tempers—hot rolled, cold rolled, and annealed—to match diverse industrial requirements. The Alloy 20 Plate offers superior machinability and can be easily welded using standard techniques, while the Alloy 20 Coil is ideal for continuous processing lines where precision and consistency are vital. Designed to deliver both performance and longevity, our Alloy 20 products are widely used across industries in India, the Middle East, Europe, and beyond. Whether you need corrosion-resistant sheets for chemical plants or precision-engineered coils for fabrication, our Alloy 20 Sheet, Plate, and Coil guarantee strength, durability, and confidence in every application.
