Japanese Standard (3)

 　　S45C

　　The Japanese JIS standard steel grade has a composition close to the national standard 45 steel. 45 steel, as a commonly used high-quality carbon structural steel, has a wide range of uses

　　S20C is a high-quality carbon structural steel material according to the Japanese JIS standard. Equivalent to China's high-quality carbon structural steel 20 # steel, it is generally replaced with China's high-quality carbon structural steel 20 # steel.

　　Carbon plate steel plate grade: S10C S12C S15C S17C S20C S22C S25C S28C S30C S33C S35C S38C S40C S43C S45C S48C S50C S53C S53C S53C S55C S55C

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

What is the use of oxygen free copper?

 　　The higher the purity of any copper product , the better its corrosion resistance, the higher its conductivity, and the less heat generated during conductivity. As the purest copper product, C101 oxygen free copper provides the best results for all copper products. 　　By removing almost all impurities, the metal structure of copper is almost uninterrupted, and by removing almost all oxygen, the oxidation of metal copper is significantly reduced, which further hinders performance. 　　Due to the high price of high-purity products, almost all uses of C101 oxygen free copper are highly specialized. This includes: 　　Excellent audio/video applications - Quality critical high-end audio/video applications will use copper wire made of C101 oxygen free copper. 　　The increase in conductivity of C101 oxygen free copper for large industrial transformers can reduce the diameter of the internal wiring in the transformer, thereby reducing the amount of copper used and the overall instal
