Material 410 stainless steel is a kind of stainless steel produced according to American Standard Specification, which is equivalent to s41000 (AISI, ASTM) or 1Cr13 in China. The carbon content is 0.15% and the chromium content is 13%. The 410 stainless steel pipe of Foshan stainless steel factory has excellent corrosion resistance and good machinability. Generally, the fan pipe @ hhmhgyhhm @ 410 stainless steel pipe heat treatment process of Foshan stainless steel pipe factory: the heat treatment temperature is 800-900 ℃, slow cooling or 750 fast cooling. Chemical composition: Cr = 11.50 ~ 13.50%, C ≤ 0.15%, Mn ≤ 1.00%, Si ≤ 1.00%, s ≤ 0.030%, P ≤ 0.035%

General stainless steel Seiko mirror character is made of 304 stainless steel plate, because other specifications of stainless steel are easy to be oxidized or the surface hardness is too high. There are three kinds of commonly used stainless steel plate: 201 drawing stainless steel precision word material selection is very important, or there are sand hole argon arc welding, so the workmanship is fine, when used as high-grade brand image display, luxury and dignity show no doubt

410 stainless steel tube is ferritic stainless steel with magnetism; After heat treatment, it hardens and has high strength; Good machinability, suitable for neutral environment. The scope of application is structural mechanical parts (fan pillar), general conventional knife edge tableware (spoon, fork, knife handle, etc.). In addition, 410 stainless steel is light in weight when its bending and torsion strength are equal, so it is also widely used to make mechanical parts and engineering structures

Surface roughness is generally seamless pipe without polishing treatment, if there is no special requirement for appearance, it will not affect the use. The products assessed by the Bureau of quality and technical supervision shall be selected for purchase. It is a direct and effective way to choose and buy products with long-term use witness and good reputation among customers. Observe whether the color of outer surface and inner wall is bright and smooth, whether the thickness is uniform or rough. General welded pipe this basic need not check, and seamless steel pipe is produced by cold drawing or hot rolling, in the production process improper operation is easy to produce uneven thickness

Stainless steel pipe has good acid and alkali resistance and corrosion resistance, so the anti-corrosion materials used by large chemical production enterprises are stainless steel pipe. The production process of industrial stainless steel pipe is one-time forming, which belongs to seamless stainless steel pipe. Industrial stainless steel pipe is widely used for conveying fluid, such as oil, natural gas, water, gas, steam and other industries. Generally speaking, the price of industrial stainless steel pipe of the same material is 1 / more than that of decorative stainless steel pipe, because of the production cost and complicated process. There will be a small amount of black leather pipe, industrial stainless steel pipe: usually the surface of industrial stainless steel pipe will be pickling pipe. As mentioned above, industrial stainless steel pipe belongs to industrial use., Because some chemical reagents will make the surface of this stainless steel black. The surface of the board is delicate, and the effect of resistance and anti fouling is very good. Secondly, the gold plating oil on the surface of this kind of stainless steel plate has good film property, high hardness, and is not easy to peel or pulverize, and this layer of transparent film can also effectively protect the surface of stainless steel plate from being scratched easily. In addition, in the appearance, it also greatly improves the cold and rigid feeling of stainless steel plate as metal, making people look more warm, and the decorative effect is also quite good. Widely used in kitchen, hotel, furniture, etc. There is no need to use metallic cleaning agent. The stainless steel plate produced in this way has several advantages. First of all, it is very easy to clean the stains on the surface of stainless steel plate. However, with so many advantages, this kind of stainless steel plate also has some disadvantages. The obvious one is that it can no longer contact with high temperature after non processing. This is because once the protective film contacts with high temperature, it will change color. Therefore, this kind of stainless steel plate cannot be used in high temperature environment

In the first half of 2018, crude steel production continued to rise. In the case of relatively rich profits of stainless steel welded pipe, the production enthusiasm of steel plants will remain high in the second half of the year. In the first half of this year, China’s economy was stable and good. Although the growth rate dropped slightly, there was still obvious growth. According to the statistical data, the demand of stainless steel welded pipe is released smoothly. In the second half of the year, some compliance projects will speed up the implementation progress, and the infrastructure will continue to be stable

铁素体不锈钢含铬15%~30%。其耐蚀性、韧性和可焊性随铬含量的增加而提高,其抗氯应力腐蚀性能优于其它类型的不锈钢,如crlcr17mo2ti、Cr25Mo3Ti、Cr28,铁素体不锈钢由于含铬量高,具有良好的耐蚀性和抗氧化性,但其力学性能和工艺性能较差。主要用于应力较小的耐酸结构和抗氧化钢。这种钢能抵抗大气和盐水溶液的腐蚀,具有良好的高温抗氧化性和较低的热膨胀系数。它可用于食品工厂和设备,也可以使零件在高温下工作,如燃气轮机零件。奥氏体不锈钢中含有18%以上的铬、8%左右的镍和少量的钼、钛、氮等元素。综合性能好,耐各种介质腐蚀
