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.

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.

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.

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.
