Yunus Sheets and Plates, located in Istanbul, Turkey, stands out as a top manufacturer and supplier of Stainless Steel 321 Coil and Slitting Coil. They pride themselves on delivering high-quality stainless steel products that meet the rigorous demands of various industrial applications. Known for their precision engineering and commitment to international standards, the company offers coils that are built to last, featuring durability, corrosion resistance, and excellent performance in high-temperature environments. The Stainless Steel 321 Coil and Slitting Coil are specifically designed to uphold structural integrity and reliability, even in the toughest conditions. Thanks to their advanced production technology and stringent quality control measures, Yunus Sheets and Plates guarantees consistent, long-lasting products that cater to industries like petrochemical, aerospace, automotive, and construction around the globe.
The Stainless Steel 321 Coil and Slitting Coil are made from a titanium-stabilized austenitic stainless steel, primarily consisting of iron, chromium (17–19%), nickel (9–12%), titanium, carbon, and trace amounts of manganese, silicon, phosphorus, and sulfur. The addition of titanium helps prevent the formation of chromium carbide, which boosts resistance to intergranular corrosion during welding. On the mechanical side, these coils deliver high tensile and yield strength, outstanding toughness, and remarkable resistance to creep and oxidation at elevated temperatures. Their unique blend of strength, thermal stability, and corrosion resistance makes Stainless Steel 321 Coil and Slitting Coil perfect for demanding industrial applications that require both durability and high performance.
