Alloy 20 Sheets, also known as Carpenter 20 or UNS N08020, are high-performance austenitic stainless steel alloys designed primarily for exceptional resistance to sulfuric acid and aggressive chemical environments. At Neonox Overseas, we specialize in manufacturing and supplying premium quality Alloy 20 Sheets that meet international standards such as ASTM, ASME, DIN, and EN. These sheets are highly versatile and widely used in industries that demand superior resistance to corrosion, pitting, and stress cracking. Unlike conventional stainless steels, Alloy 20 offers excellent mechanical strength along with outstanding resistance to acids such as sulfuric, nitric, and phosphoric, making it a cost-effective alternative to high-nickel alloys.
One of the key advantages of Alloy 20 Sheets is their ability to withstand chemical processing environments while maintaining durability and toughness. The addition of nickel, chromium, and copper in Alloy 20 provides excellent resistance against oxidizing and reducing conditions, while molybdenum enhances resistance to localized corrosion such as crevice and pitting attacks. These properties make Alloy 20 Sheets suitable for equipment used in the petrochemical industry, pharmaceutical processing, food and beverage production, pickling tanks, storage vessels, and heat exchangers. They are also widely used in flue gas desulfurization systems, marine environments, and synthetic fiber manufacturing.
At Neonox Overseas, we offer Alloy 20 Sheets in a wide range of forms, sizes, and thicknesses to cater to different industrial needs. Whether you require hot-rolled Alloy 20 Sheets for structural applications or cold-rolled Alloy 20 Sheets for precision engineering, we ensure consistent quality and superior finishing. We also provide Alloy 20 Shim Sheets for critical tolerance requirements, Alloy 20 Chequered Sheets for flooring and structural applications, and Alloy 20 Perforated Sheets for filtration and ventilation systems. In addition, Alloy 20 Plates and Coils are available to support bulk industrial requirements, while Alloy 20 Strips and Foils are ideal for specialized manufacturing.
Neonox Overseas is committed to maintaining the highest standards of quality, and all our Alloy 20 products undergo stringent testing such as mechanical tests, corrosion tests, PMI (Positive Material Identification), and ultrasonic testing to ensure reliability. We supply Alloy 20 Sheets in both standard and custom dimensions, with surface finishes like 2B, BA, No. 4, and mirror polish, making them suitable for a wide variety of end uses. With global exports across Asia, Europe, Africa, and the Middle East, we are trusted by industries worldwide for timely delivery, competitive pricing, and uncompromised quality.
Choosing Alloy 20 Sheets from Neonox Overseas guarantees superior corrosion resistance, mechanical strength, and long-term performance in demanding environments. Whether your application involves chemical plants, food processing, or marine exposure, our Alloy 20 Sheets deliver the durability and efficiency your projects require. With our expertise, global presence, and commitment to excellence, we ensure that clients receive Alloy 20 Sheets that exceed expectations in quality, performance, and reliability.
