Introduce

Drawing is the non-ferrous metal industry in cold drawn tubes today's popular surface treatment technology, and 304 stainless steel tube drawing is a kind of metal processing technology, often asked, after 304 stainless steel tube drawing whether can rust? Let double hing small make up today to popularize the knowledge for everyone.
Stainless steel pipe is corrosion resistant steel, and its main components such as iron, carbon, nickel, chromium element. Chrome will form a chromium layer protective film on the surface of stainless beam impact tubes steel pipe, prevent the stainless steel tube further oxidation corrosion. And 304 stainless steel tube after wire drawing processing, rich chromium coating on the surface of the damage, the corrosion resistance of stainless steel pipe to reduce because of this, is easy to appear rusty phenomenon.
Stainless steel pipe common surface treatment can be divided into light and inferior smooth surface. Drawing inferior smooth surface than ordinary stainless steel bright surface wear-resisting, looks more grade, which is deep popular, although 304 stainless steel tube after dealing with the drawing, but there is some rust effect, than ordinary light side impact beams tube performance than just did fall.
304 stainless steel tube after dealing with the drawing while still has certain effect of corrosion resistance, rust, try not to use in outdoor exposure, use indoors is not only beautiful, but also in the indoor environment, rust is enough, if on the outside, should pay attention to maintenance. Regularly to the stainless steel pipe brush anti-rust oil, pay attention to protect don't let the damage to the surface of the stainless steel pipe.
cold drawn tubes 304 stainless steel service pipe is stronger than other tap water pipeline safety coefficient of performance, and the wear-resisting performance conforms to the requirements.
Jagged on the stainless steel pipes, currently on the market is not the same as the raw material price nature have high low, as a general consumer, how you tell the difference between 304 and 201 stainless steel pipe. Below small make up with the three methods.
Teach you the difference between 304 and 201 stainless steel pipe:
1, watching the anti-fake mark on stainless steel pipe. Stainless steel pipe in the general case are playing anti-fake mark, on the surface of the concrete is playing in one pipe fitting, generally 60 ~ 100 cm right in the middle will have an anti-counterfeiting mark, anti-counterfeit marking Contains such contents: the raw material of stainless steel pipe, stainless steel pipe producers or famous brand.
2, beam impact tubes 304, and 201 stainless steel pipe, generally for inferior smooth surface. On the basis of people watching, to identify the hands touching way: 304 stainless steel pipe has good smoothness, hand touch very smooth; 201 stainless steel sheet, color dark no smoothness, will touch Feels more uneven uneven. Wet water, in addition to hand touch 2 kinds of metal materials, the water damage of the put apart after touching hands fingerprints, the comparison of 304 stainless steel plate is easy to wipe down, 201 is not easy to wipe down.
3, use polishing machine fitted with two board or tube polishing disc slowly grinding polishing, buffing 201 raw materials of flame is long, thick, many, in turn, 304 flame short, thin, less raw material. Remember that fine polishing when the strength of the light and amplitude
To such as consistent as far as possible.
Stainless steel pipe is a hollow oblong steel, widely used in petroleum, chemical, medical, food, industrial pipeline, such as heat exchanger. In addition, when the torsional strength and bending strength at the same time, compared with lighter weight, which is widely used in engineering structures .
side impact beams With the constant improvement of the life needs. Some large manufacturing industry development, improve the production of many enterprises. Through the use of these steel pipes to improve the quality of products, to promote it to a new level. This kind of product in the process of production is strictly to O. The production process is also very complex. In the production process can maintain its own function, stability and corrosion resistance is strong. Its production requirement is very high. Different types of 304 stainless steel pipe with different properties.
What is the 304 stainless steel?
304 stainless steel is a kind of austenitic steel, contains 35% of nickel, chromium content of 16% to 24%. 18-8 is the most common type of 304 stainless steel or steel 18/8, consisting of 18% 8% of the nickel and chromium; Still contain among them about 0.03% of the sulfur, 0.1% N, 0.08% of carbon, silicon, 2%, 0.75% 0.045% of manganese and phosphorus.
