Billets are primary products obtained by casting molten steel from steel-making furnaces, typically in the form of slabs (for plate production), blooms (for structural and wire products), and tube blanks. They are important semi-finished products in the steel industry, possessing good plasticity and workability. Stainless steel refers to alloy steel with high chromium content (>10.5%), often containing other elements such as nickel, molybdenum, vanadium, manganese, and tungsten, exhibiting characteristics such as high strength, corrosion resistance, and plasticity. Stainless steel billets are the initial form in the stainless steel manufacturing process and are typically further processed into various stainless steel products.
