Yunus Sheets and Plates, located in Istanbul, Turkey, is a reputable manufacturer and supplier of Stainless Steel 347 Coil and Slitting Coil. They pride themselves on delivering high-quality stainless steel products that are engineered for both performance and reliability. Renowned for their precision manufacturing and adherence to international standards, the company produces coils that boast excellent corrosion resistance, high-temperature stability, and impressive mechanical strength. The Stainless Steel 347 Coil and Slitting Coil are specifically designed to endure tough industrial environments while keeping their structural integrity intact. With state-of-the-art production facilities and rigorous quality control measures, Yunus Sheets and Plates guarantees durable and trustworthy products that are perfect for use in the petrochemical, automotive, aerospace, power generation, and construction sectors.
The Stainless Steel 347 Coil and Slitting Coil are a stabilized austenitic stainless steel primarily made up of iron, chromium (17–19%), nickel (9–12%), niobium (columbium), carbon, and trace amounts of manganese, silicon, phosphorus, and sulfur. The addition of niobium acts as a stabilizer, preventing the formation of chromium carbide and providing outstanding resistance to intergranular corrosion. On the mechanical side, these coils deliver high tensile and yield strength, remarkable toughness, and exceptional performance even at elevated temperatures. Their unique blend of thermal stability, corrosion resistance, and mechanical durability makes the Stainless Steel 347 Coil and Slitting Coil ideal for demanding industrial applications that require materials to perform reliably over the long haul.
