With a titanium content of not less than 5 times the carbon content, Type 321 stainless steel offers oxidation resistance at 816°C (1500 °F) and higher creep and stress fracture properties than 304 and 304L alloys. It also has good low-temperature toughness. It is primarily used in aerospace, petrochemical, power, automotive exhaust, and food processing equipment.

301 is the steel grade most easily strengthened by cold deformation. Cold distortion processing increases the strength and hardness of the steel and retains sufficient plasticity and toughness. In addition, this steel has good rust resistance under atmospheric conditions, but it is highly corrosive. It is mainly used in automobile industry, electronic and electrical appliances, hardware products, building decoration and so on.

Stainless steel plate has a smooth surface, high plasticity, toughness and mechanical strength, and can resist the corrosion of acidic and alkaline gases, solutions and other media. It is an alloy steel that is not easy to rust, but it is not absolutely rust-free. Stainless steel plate is a steel plate that can resist the corrosion of weak media such as air, steam and water, while acid-resistant steel plate can resist the corrosion of chemical media such as acid, alkali and salt.

A seamless stainless steel pipe is a long piece of steel with a hollow cross-section and no seams around it. It is made from ingots or solid billets that are pierced to make a burr pipe, which is then hot rolled, cold rolled or cold dialed. Due to its lack of welded seams, the overall structure is uniform and stronger, able to withstand higher pressures and stresses. The dimensional accuracy is relatively high, with smaller tolerances on inner and outer diameters and good roundness. The production process is complicated and the cost is high.

Type 201 stainless steel is a low-cost alternative to traditional chromium-nickel stainless steels such as 301 and 304, where the nickel is replaced by added manganese and nitrogen.Type 201 is essentially non-magnetic in the annealed condition, but becomes magnetic after cold working and can achieve high tensile strengths.Type 201 can be used as a replacement for Type 301 in many applications. It is used primarily for decorative piping, industrial piping, and some shallow drawn products.

304 stainless steel is a general-purpose stainless steel material with better rust resistance than 200 series stainless steel materials. High temperature resistance is also better, up to 1000-1200 degrees.304 stainless steel has excellent corrosion resistance and good intergranular corrosion resistance, high strength and toughness, smooth and beautiful surface, easy to process. It is mainly used in building decoration, kitchenware and tableware, food processing equipment, medical equipment, chemical equipment, automobile parts and so on.

310 is an austenitic stainless steel with excellent high temperature properties, good ductility and weldability. It is commonly used in high-temperature applications because of its high chromium and nickel content, which provides solid corrosion resistance at temperatures up to 2100 °F, excellent oxidation resistance, and outstanding strength that is superior to 304 or 309 stainless steel. It is widely used in kilns, high-temperature furnaces, boilers, furnace linings, and other high-temperature equipment.

Compared with 304 stainless steel plate, 316 stainless steel plate has a molybdenum content of 2-3%, which makes it more resistant to corrosion by acids, alkalis, salts and other chemicals, and is especially resistant to chlorides, which makes it suitable for a variety of harsh corrosive environments. It is usually used in pulp and paper equipment, heat exchangers, dyeing equipment, film processing equipment, pipelines, building exterior materials in coastal areas, and bracelets and cases of high-grade watches.

With a titanium content of not less than 5 times the carbon content, Type 321 stainless steel offers oxidation resistance at 816°C (1500 °F) and higher creep and stress fracture properties than 304 and 304L alloys. It also has good low-temperature toughness. It is primarily used in aerospace, petrochemical, power, automotive exhaust, and food processing equipment.
