SS316, also known as 316 stainless steel, is a corrosion-resistant and high-strength material composed of approximately 16-18% chromium (Cr), 10-14% nickel (Ni), and 2-3% molybdenum (Mo). It is widely used in various industries such as marine, aerospace, chemical, petrochemical, as well as in architectural and structural applications. SS316 exhibits excellent corrosion resistance, high tensile strength, and good heat resistance, making it suitable for applications involving corrosive environments and elevated temperatures. It has an austenitic crystal structure, is non-magnetic, and offers good formability and weldability, making it versatile for different manufacturing processes. Additionally, SS316 is commonly used in food processing, pharmaceutical, and medical industries due to its hygienic and sanitary properties.
