High - strength welded square tube for build
A welded square tube is a hollow structural section (HSS) characterized by its square shape and uniform wall thickness. It is produced by taking flat steel sheets, forming them into a square shape, and then welding the edges together to create a strong, seamless tube. This manufacturing process not only enhances the structural integrity of the tube but also allows for a variety of sizes and thicknesses to meet specific project requirements.

304 seamless, strong, high - use, corrosion - proof
304 seamless steel pipe is a seamless steel pipe made of 304 stainless steel as raw material. 304 stainless steel belongs to austenitic stainless steel, and its main chemical composition is as follows:
Chromium (Cr): The content is about 18% - 20%. Chromium is the key element that makes stainless steel corrosion-resistant. It can form a dense chromium oxide protective film on the surface of stainless steel to prevent further corrosion of the steel by external media.
Nickel (Ni): The content is generally in the range of 8% - 10.5%. The addition of nickel helps to stabilize the austenite structure, giving stainless steel good toughness, plasticity and machinability, and can further enhance the corrosion resistance of stainless steel, especially in some highly corrosive environments such as chloride ions.
Carbon (C): The content is relatively low, usually not exceeding 0.08%. The lower carbon content helps to reduce the precipitation of carbides and avoid adverse effects on the corrosion resistance and toughness of stainless steel.
In addition, it also contains a small amount of impurity elements such as manganese (Mn), silicon (Si), phosphorus (P), and sulfur (S), but their contents are strictly controlled at a low level to ensure the excellent performance of stainless steel.Brands from various countries that match 10# steel: ASTM A240/A240M - 304、DIN EN 10088-2 - 1.4301、JIS G4305 - SUS304、ГОСТ 5632-72 - 08Х18Н10
