Why Is There A Big Difference in The Price Of 304 Stainless Steel Pipe?

Although the material is 304, but each 304 stainless steel pipe manufacturers smelting technology, the chemical element content index is different, the quality is different, the price difference is about 10%. And there are quality differences in the manufacturing process of each pipe factory, and the performance and corrosion resistance are strong and weak after use. Poor quality even if the recent rust, but a long time will become gray color, yellow, and even rust. In the face of the uneven and complex stainless steel market and related to the building decoration of a hundred years, you have to make a wise choice. First of all, whether the tube surface is marked with steel material "304", and to obtain the manufacturer's quality certificate and quality guarantee certificate. Secondly, the color of the outer surface and the inner wall of the tube is bright and smooth, the thickness is uniform, or there is a rough phenomenon. When choose and buy, should choose by the quality and technical supervision bureau of the evaluation of brand-name products at the provincial level. In the customers have a long time to use the witness and good reputation is the most direct and effective purchase method.

304 is a kind of universal stainless steel, which is widely used in the production of equipment and parts requiring good comprehensive performance (corrosion resistance and molding). In order to maintain the corrosion resistance inherent in stainless steel, the steel must contain at least 18% chromium and at least 8% nickel. 304 stainless steel is a grade of stainless steel produced according to ASTM standards in the United States. 304 stainless steel is a common material in stainless steel, density of 7.93g /cm3, the industry is also called 18/8 stainless steel. High temperature resistance of 800 degrees, with good processing performance, high toughness, widely used in industrial and furniture decoration industry and food and medical industry.
