Stainless steel sheets are an alloy of iron, chromium (at least 10.5%), and other elements like nickel, which provides corrosion and rust resistance, durability, heat resistance, and a hygienic, aesthetic surface. Key properties include strength, formability, weldability, and easy maintenance. Common applications span the construction, automotive, and medical industries, and for items like kitchenware, due to their versatility and longevity. When purchasing, consider the specific grade (like 304 or 316), thickness, sheet size, and finish.
