National Standard Properties of 304 Stainless Steel Plate

图片
　　 304 stainless steel plate tensile strength (Mpa) 520 　　Yield strength of 304 stainless steel plate (Mpa) 205-210 　　Elongation rate of 304 stainless steel plate (%) 40% 　　304 stainless steel plate hardness HB187 HRB90 HV200 　　The density of 304 stainless steel is 7.93 g/cm3. Austenitic stainless steel generally uses this value. The chromium content (%) of 304 is 17.00 to 19.00, and the nickel content (%) is 8.00 to 10.00304, which is equivalent to 0Cr19Ni9 (0Cr18Ni9) stainless steel in China 　　304 stainless steel is a versatile stainless steel material with stronger rust resistance than the 200 series stainless steel material. It also has good resistance to high temperatures. 　　304 stainless steel has excellent rust resistance and good intergranular corrosion resistance. 　　For oxidizing acids, it was found in experiments that 304 stainless steel has strong corrosion resistance in nitric acid below boiling temperature with a concentration of ≤ 65%. It also has good cor

Advantages of extruded aluminum

图片
 　　 Extruded aluminum has many advantages compared to other metals. Some metals can match some of the ideal properties of aluminum, but no metal can match all of these advantages simultaneously. 　　There are many benefits of aluminum profiles, including: 　　Light. The weight of aluminum is about one-third of the weight of iron, steel, copper, or brass. This makes it easier to handle and transportation more economical. Therefore, aluminum is widely used in automotive design, aerospace, and high-rise buildings. 　　Strong. The strength of aluminum is sufficient to meet all applications except for the most demanding ones. Aluminum is very suitable for cold environments as it becomes stronger as the temperature decreases. 　　Corrosion resistance. Aluminum does not rust. It is protected by oxide surface facial mask, and this protection can be enhanced by anodic oxidation. 　　Excellent thermal conductivity. Aluminum has better thermal conductivity than most metals. This makes it an
