Based in Chennai, India, Kunj Sheets and Plates is a well-known producer and supplier of high-quality Alloy 20 foils. Alloy 20 is an austenitic stainless steel designed for exceptional performance in applications involving sulphuric acid and chloride, and it is engineered to withstand severe corrosion in harsh chemical environments. Kunj guarantees that every foil product satisfies customer requirements and global standards, making them perfect for crucial industrial applications. Modern manufacturing techniques, meticulous finishing, and an emphasis on quality control have made Kunj a reliable supplier of Alloy 20 foils for sectors including food processing, chemicals, petrochemicals, and pharmaceuticals.
Nickel (32–38%), chromium (19–21%), iron (balance), molybdenum (2–3%), copper (3–4%), and trace amounts of manganese, silicon, and niobium make up the special composition of Alloy 20 Foils. Excellent corrosion resistance is provided by this combination, especially against stress corrosion cracking caused by sulphuric acid and chloride. It offers good elongation of about 30%, a tensile strength of 550 MPa, and a yield strength of about 240 MPa. Alloy 20 foils are appropriate for high-performance, corrosion-prone applications that demand formability and durability because they maintain their strength and ductility in harsh environments.
