Stainless steel sheet is a highly versatile rolled flat steel material, divided into three main categories: cold-rolled thin sheet, hot-rolled medium and heavy plate, and industrial heavy plate. It covers the entire range of materials including chromium-manganese-nickel series, austenitic, ferritic, and duplex steel. The mainstream grades include 201, 304, 304L, 316, 316L, 321, 310S, 430, 2205, etc.

Stainless steel coils are the basic raw material for both cold-rolled and hot-rolled stainless steel processes. They serve as the precursor base material for various stainless steel sheets, pipes, and stamped parts, encompassing two main categories: cold-rolled and hot-rolled stainless steel coils. The full range covers materials such as SUS200 chromium-manganese-nickel, SUS300 austenitic, SUS400 ferritic/martensitic, duplex steel, and high-temperature resistant special steel. Mainstream grades include 201, 304, 304L, 316, 316L, 321, 310S, 430, 1Cr13, 3Cr13, and 2205.

Stainless steel rods can be divided into three types according to production technology: hot rolling, forging and cold drawing. The specifications of hot-rolled stainless steel round bars are 5.5-250 mm. Among them: small stainless steel round bars of 5.5-25 mm are mostly supplied in straight strips and are commonly used as steel bars, bolts and various mechanical parts; stainless steel round bars larger than 25 mm are mainly used to manufacture mechanical parts or seamless steel pipe blanks .

Stainless steel round bars, also known as stainless steel round bars, are long strips of stainless steel with a solid circular cross-section. They are divided into three categories: hot-rolled round bars, cold-drawn round bars, and precision-ground round bars. The mainstream materials used are 304, 304L, 316, 316L, 321, 410, 420, and 430, which are processed through multiple processes such as smelting, rolling, drawing, polishing, and precision grinding.

Stainless steel square bars are square-section bars made from stainless steel and belong to the steel material category. The main materials include 200 series (chromium-nickel-manganese austenitic), 300 series (chromium-nickel-austenitic), and 400 series (ferritic/martensitic) stainless steels. Among them, grades such as 304 and 316L achieve corrosion resistance, high temperature resistance, and high strength through low-carbon design (e.g., the suffix "L") or alloy composition adjustments. The density of 304 stainless steel is 7.93 g/cm³, equivalent to that of Chinese 0Cr19Ni9 stainless steel.

Stainless steel flat steel can be composed of various stress components according to the different needs of the structure, and can also be used as a connector between components. Widely used in various building structures and engineering structures, such as beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks and warehouse shelves, etc.

201 stainless steel bars belong to manganese-substituted nickel austenitic stainless steel, and are also commonly referred to as 201 stainless steel round bars. They are available in hot-rolled, cold-drawn, bright round, and precision-ground varieties, with a solid circular cross-section.

304 stainless steel bars are the most widely used general-purpose austenitic stainless steel round bars. They have a solid circular cross-section and are mainly divided into four categories: hot-rolled round bars, cold-drawn round bars, bright round bars, and precision-ground round bars.

316L stainless steel bars are solid round bars made of low-carbon austenitic stainless steel. They are a major category of high-end anti-corrosion materials, available in hot-rolled, cold-drawn, bright, and precision-ground varieties. The material incorporates molybdenum and uses an ultra-low carbon formula, processed through rolling, cold drawing, polishing, and precision grinding. It possesses superior corrosion resistance, high-temperature resistance, acid and alkali resistance, and easy weldability, with overall performance exceeding that of 304 stainless steel. It is widely used in harsh environments such as highly corrosive conditions, marine applications, chemical plants, and medical settings.
