2, simple classification of stainless steel
Stainless steel can be roughly divided into 200 series, 300 series and 400 series of three categories, of which 300 series is the most commonly used, 200 series and 400 series is a replacement for 300 series, and strictly speaking, 400 series is not called stainless steel, called stainless iron, because there is no nickel element, so the magnet can attract.And 200 series and 300 series are nickel, so there is no magnetic, iron can not absorb.
304 is the most common variety in the 300 series, so generally from the price change of 304 can be judged the price trend of the whole stainless steel.The 200 series contains less nickel, the 400 series contains no nickel, and the 300 series contains the most nickel, so the 300 series is the most affected by nickel price.

300 series can be simply divided into 304, 304L, 316, 316L, 321, 309S, 310S and so on, the basis of the difference is the content of various metal elements, different content of stainless steel characteristics are not the same, 304 and 304L is different in carbon (C) content, with L is said to contain low carbon, also known as low carbon,Same difference between 316 and 316L.
