Product Detail
Color stainless steel plate:
Color stainless steel plates are more and more widely used. Chinese colored stainless steel not only has the unique luster and strength of metal, but also has a colorful and long-lasting color. The color stainless steel plate not only maintains the physical, chemical and mechanical properties of the primary color stainless steel, but also has stronger corrosion resistance than the primary color stainless steel.
Introduction:
In recent years, the color stainless steel plate has become more and more widely used due to its uniqueness. Now, a large number of colored stainless steel products are used for decoration in buildings abroad, and colored stainless steel plates have been all the rage. Chinese colored stainless steel not only has the unique luster and strength of metal, but also has a colorful and long-lasting color. The color stainless steel plate not only maintains the physical, chemical and mechanical properties of the primary color stainless steel, but also has stronger corrosion resistance than the primary color stainless steel. Therefore, since its inception in the 1970s, it has been widely used in the fields of building materials, chemical industry, automobile, electronics industry and arts and crafts.
Among the commonly used primary color stainless steels, austenitic stainless steel is the most suitable coloring material, which can obtain a satisfactory color appearance. The ferrite stainless steel will increase the possibility of corrosion in the coloring solution, and the resulting color is not as bright as the former. The low-chromium high-carbon martensitic stainless steel, because of its poor corrosion resistance, can only get a dull color or black surface. According to reports, after austenitic stainless steel is colored by low-temperature surface oxidation treatment, it is exposed to the industrial atmosphere for 6 years, exposed to the marine atmosphere for 1 and a half years, soaked in boiling water for 28 days, or heated to about 300 ℃ , Its color gloss has not changed. In addition, it can also withstand general molding, drawing and bending, and work hardening. WiQ Industrial Design. China At present, colored stainless steel can be used in many other fields besides building exterior wall and window frame decoration. For example, a black stainless steel plate can be used to make the solar heat collecting plate, and the selected heat absorption rate can reach 91% to 93%. In the field of arts and crafts, the combination of colored stainless steel and printing can be combined with etching and grinding and the dot method to produce three-dimensional relief murals and screens that never fade. In addition, the use of colored stainless steel to manufacture household appliances, cooking utensils, kitchen equipment, and toilet appliances will be deeply loved by consumers.
Which is better ss304 or ss316?
Since Type 316 stainless steel alloy contains molybdenum bearing it has a greater resistance to chemical attack than 304. Type 316 is durable, easy-to-fabricate, clean, weld and finish. It is considerably more resistant to solutions of sulfuric acid, chlorides, bromides, iodides and fatty acids at high temperature.
What is good quality stainless steel?
304 stainless steel is the most common form of stainless steel used around the world due to excellent corrosion resistance and value. 304 can withstand corrosion from most oxidizing acids. That durability makes 304 easy to sanitize, and therefore ideal for kitchen and food applications.
What is the difference between 304, 304H and 304L?
In fact, the content of chromium and nickel is 304 stainless steel, and the composition contains 18% chromium (Cr) and 8% nickel (Ni), but the main difference lies in the carbon content.
304L is an ultra-low carbon stainless steel. The carbon content is reduced to less than 0.03%, which can avoid intergranular corrosion. In theory, the effect of stress corrosion resistance is stronger than that of 304, but the effect is not obvious in practical applications. The purpose of reducing carbon and adding titanium is the same, but the smelting cost of titanium-added 321 is higher, the molten steel is thick, and the price is more expensive.
The H in 304H refers to high temperature. High carbon content is the guarantee of high temperature strength. GB150 requires that when austenitic steel is used above 525 degrees, the carbon content should not be less than 0.04%. Carbide is the strengthening phase, especially the high temperature strength. Better than pure austenite.
Among the three, the highest carbon content is 304H, the lowest carbon content is 304L, and the carbon content of 304 stainless steel is between the two. The higher the carbon content, the worse the corrosion resistance of stainless steel and the easier it is to rust. The difference in carbon content also causes the price to be different, or the requirements for different uses are also different.
Why is stainless steel so expensive?
Stainless steel is more expensive to produce because of the addition of the variety of alloying elements, such as iron, chromium, nickel, manganese and copper. … The chromium attaches itself to oxygen more readily than iron and thus creates a chromium oxide layer which protects the metal from degradation.
What is the safest stainless steel?
Stainless steel cookware is generally recognized as a safe material for cookware. Any good quality stainless steel, be it 304 or 316 stainless steel, is a better choice than most of the other available materials. For example, coated aluminum pans lose their non-stick over time.
