Stainless metals, or stainless steel, are versatile alloys primarily made of iron and chromium, with additional elements like nickel, molybdenum, and manganese. The chromium content, usually at least 10.5%, forms a passive layer of chromium oxide that provides outstanding resistance to rust, corrosion, and staining. This property makes stainless steel suitable for a wide range of applications, from construction and automotive to aerospace, medical devices, and food processing.
Various grades of stainless steel, including austenitic, ferritic, martensitic, and duplex, are tailored for specific uses. Austenitic stainless steel is valued for its formability and corrosion resistance, making it ideal for kitchen appliances and architectural panels. Ferritic stainless steel is used in automotive exhaust systems for its stress corrosion resistance, while martensitic stainless steel’s strength and hardness are suited for cutting tools and surgical instruments. Duplex stainless steel offers a combination of properties from both austenitic and ferritic types, making it effective in challenging environments like marine and chemical processing. Its low maintenance, high strength-to-weight ratio, and aesthetic appeal contribute to its durability and cost-effectiveness in various applications.
