SUS304—also known as 18/8 or 18/10 stainless steel (UNS S30400)—is the most widely used austenitic stainless alloy worldwide. With 18–20% chromium and 8–10.5% nickel, plus small amounts of carbon, manganese, silicon, and nitrogen, it delivers excellent corrosion resistance, formability, and weldability across a vast temperature range. From food processing equipment and architectural facades to chemical […]

Stainless steel is categorized into five primary families—Austenitic, Ferritic, Martensitic, Duplex, and Precipitation-Hardening—each defined by its metallurgical structure and alloying elements. These families encompass hundreds of specific grades tailored for diverse applications in food processing, chemical plants, architecture, automotive, and medical devices. Understanding the distinctions between each family and key grades enables engineers to optimize
