304 stainless steel pipe has beautiful surface and diversified usage possibilities, good corrosion resistance, longer durability than ordinary steel, and higher strength, so thin pipes are more likely to be used, resistant to high temperature oxidation and high strength, so they can resist fire and room temperature processing, that is, easy to plastic Because the processing does not require surface treatment, it is simple, simple to maintain, clean, high in finish, and good in welding performance. The most common filaments and short wires on the market are the 304 stainless steel pipes after processing such surfaces, showing good decorative effects, which can satisfy General requirements for decorative materials. Generally speaking, 304 series stainless steel can form a good effect after a frosting. Due to the low cost, simple operation, low processing cost, and wide application of such processing equipment, it has become a necessary equipment for processing centers. Therefore, most machining centers can provide frosted pipes of filament and short filament, of which 304 steel accounts for more than 80%.

The surface quality of 304 stainless steel is mainly determined by the pickling process after heat treatment. If the surface oxide scale formed by the previous heat treatment process is thick or the structure is uneven, pickling will not improve the surface finish and uniformity. Therefore, full attention should be paid to the heating of heat treatment or the surface cleaning before heat treatment. If the thickness of the surface oxide scale of the stainless steel pipe is not uniform, the surface finish of the base metal under the thick and thin areas is also different, and the dissolution of the surface oxide scale during pickling and the degree of corrosion of the base metal at the attachment position of the oxide scale by acid Different, so the surface of the steel pipe is not uniform. Therefore, during the heat treatment heating, it is necessary to uniformly form oxide scale.

　　 304 stainless steel pipe is used as a stainless heat-resistant steel for food equipment, general chemical equipment, and nuclear energy industry equipment. The anti-rust performance of 304 stainless steel is stronger than that of 200 series stainless steel. High temperature resistance is also better, as high as 1000-1200 degrees. 304 stainless steel has excellent stainless corrosion resistance and good intergranular corrosion resistance. 304 stainless steel material has strong corrosion resistance in nitric acid with a concentration of ≤65% below the boiling temperature. It also has good corrosion resistance to alkaline solutions and most organic and inorganic acids. A high-alloy steel that can resist corrosion in the air or in chemically corrosive media. Stainless steel has a beautiful surface and good corrosion resistance. It does not need to undergo surface treatments such as plating, but uses the inherent surface properties of stainless steel. It is used in many A kind of steel, usually called stainless steel. High-alloy steels such as 13 chrome steel and 18-8 chrome-nickel steel represent performance.
