MERIH STAINLESS, based in Istanbul, Turkey, is a reputable manufacturer and supplier of top-notch Stainless Steel 321 Coils, specifically crafted for demanding industrial applications. These coils are celebrated for their durability, resistance to corrosion, and ability to withstand high temperatures, making them a go-to choice in industries that require precision-engineered materials. The titanium stabilization in Stainless Steel 321 effectively prevents intergranular corrosion, ensuring reliable performance even when faced with thermal stress. MERIH STAINLESS adheres to international standards in producing these coils, providing dependable solutions for sectors like petrochemical, chemical processing, power generation, aerospace, and automotive, where strength, longevity, and quality are paramount.
Stainless Steel 321 Coils are a type of austenitic stainless steel that contains 17–19% chromium, 9–12% nickel, and titanium to enhance stability. The inclusion of titanium helps to prevent carbide precipitation, offering excellent resistance to intergranular corrosion while maintaining mechanical stability at elevated temperatures. These coils boast a tensile strength of around 515 MPa, a yield strength of 205 MPa, and outstanding resistance to creep and stress-rupture. With impressive oxidation resistance up to 870°C, along with good weldability and durability, Stainless Steel 321 Coils are ideal for applications that require prolonged exposure to heat and corrosive environments.
