F304 (X5CrNi18-10) is an austenitic stainless steel with excellent corrosion resistance, good mechanical properties, and outstanding formability and weldability. It is the most commonly used stainless steel grade, equivalent to AISI 304 and 06Cr19Ni10 (GB). This material is ideal for a wide range of structural, industrial, and consumer applications requiring durability and corrosion resistance.
