Renowned for producing and supplying high-performance nitronic sheets and plates, Kunj Sheets and Plates is based in Chennai, India. We are renowned for producing high-end stainless steel alloys, with a focus on Nitronic grades that provide remarkable durability, strength, and resistance to corrosion. These sheets and plates are appropriate for demanding industrial applications because they are produced with cutting-edge technology and in accordance with international standards. Kunj Sheets and Plates caters to a wide range of customers in industries like pulp and paper, chemical processing, marine, and aerospace with an emphasis on accuracy, prompt delivery, and customer satisfaction.
Austenitic stainless steels known as “nitronic sheets and plates” are usually made up of nitrogen, manganese, nickel, and chromium (20–23%), with trace amounts of silicon and molybdenum. The yield strength of these alloys is double that of standard 300 series stainless steels. Nitronic alloys maintain their toughness and strength at high temperatures and show exceptional corrosion resistance, particularly in acidic and marine environments. They are appropriate for structural and high-stress industrial applications because of their tensile strength, which ranges from 690 to 960 MPa, as well as their good ductility and impact resistance.
