321 stainless steel bars are solid round bars made of titanium-stabilized austenitic stainless steel, mainly categorized as hot-rolled round bars, cold-drawn round bars, bright round bars, and precision-ground round bars. The addition of titanium effectively inhibits intergranular corrosion at high temperatures, resulting in outstanding high-temperature resistance and creep resistance, while retaining the excellent toughness, weldability, and general corrosion resistance of austenitic stainless steel.

420 stainless steel bars are solid round bars belonging to martensitic stainless steel, mainly divided into hot-rolled round bars, cold-drawn round bars, bright round bars, and precision-ground round bars. This material has a high chromium content, possessing excellent hardness, strength, and wear resistance. Hardness and wear resistance can be significantly improved through heat treatments such as quenching and tempering, while also having basic rust prevention capabilities.

430 stainless steel bars are solid round bars of ferritic stainless steel, available in hot-rolled, cold-drawn, bright round, and precision-ground varieties. They contain no nickel and possess good rust resistance due to their high chromium content. The material is soft, easily bent, easy to machine, and offers excellent value for money. Its hardness cannot be increased through heat treatment. Processed through rolling, cold drawing, and polishing, it is a commonly used and economical stainless steel material for decorative hardware, kitchen and bathroom products, and general structural components.

Stainless steel round tubes are hollow circular cross-section tubes, divided into two main categories: seamless round tubes and welded round tubes. They are made from stainless steel raw materials such as 201, 304, 304L, 316, 316L, 321, and 430, and are manufactured through processes such as hot rolling, cold drawing, coil welding, polishing, and finishing.

Stainless steel square tube is a hollow long steel material. It is called a square tube because its cross section is square. They are widely used as pipelines for transporting fluids, such as oil, natural gas, water, coal gas, steam, etc. In addition, they are lighter in weight when the bending and torsional strength are the same, so they are also widely used in the manufacture of mechanical parts and engineering structures.

Stainless steel rectangular tubes are a type of shaped tube, specifically a hollow, long strip of steel. Compared to round tubes, shaped tubes (such as rectangular tubes) generally have a larger moment of inertia and section modulus, resulting in greater bending and torsional resistance. This allows for weight reduction in structures and the saving of steel.

201 stainless steel plate is a material with many excellent properties. It contains elements such as chromium, manganese, nickel, etc., has certain acid and alkali resistance, high strength, and high temperature oxidation resistance. 201 stainless steel plate has a smooth and beautiful surface, is easy to process, and is suitable for cutting, bending, punching, welding and other processes. It is widely used in architectural decoration, kitchen equipment, auto parts and other fields. It is a cost-effective and widely used stainless steel material.

201 stainless steel pipe is a welded steel pipe made of 201 stainless steel, which has the characteristics of good corrosion resistance, high density, polishing without bubbles, etc. It is widely used in decorative pipes, industrial pipes and some shallow drawing products, such as building decoration, furniture manufacturing, tableware and other fields. Although its corrosion resistance is slightly inferior to 304 stainless steel, it still has a place in the market with its lower cost and good processing performance.

304 stainless steel plate is a widely used austenitic stainless steel material with good corrosion resistance, heat resistance and processing performance. It is mainly composed of 18% chromium and 8% nickel, suitable for a variety of manufacturing and construction applications, such as kitchen equipment, food processing machinery, building decoration, etc. Its stable performance makes it the material of choice in many industries.
