DATE:2016-6-22 HITS:191

Buy stainless steel, when businesses will provide a series of code, such as 304,321,408, etc., are not familiar with the steel industry for some users might be confused to hear these figures, who in the end is what to do ??

Of course, the 304 and 321 belong to the same class of 300 series stainless steel. They are produced in accordance with standard grades of stainless steel, 304 stainless steel tube is equivalent to our 0Cr18Ni9 tube, its composition of 19% chromium, 9% nickel, 304 stainless steel used in the industry as the most widely used products, tableware and more used , railings, medical equipment among. The 302 is then processed on its basis, especially titanium elements added to improve the corrosion tendency between crystals, reducing the risk of corrosion of the weld material, so that the final product has a better corrosion resistance and temperature resistance. Its temperature resistance solves the problems encountered by other models, reflecting the high-pressure high-temperature boiler tubes neatly in its value, at high temperatures can still maintain a good long-term stability.

After the above description, I believe users for these two different types of steel have more in-depth understanding of the process in the future, please buy a lot of attention.
