Stainless steel can be superficial divided into 200 series, 300 series and 400 series of three categories, the 300 series is the most commonly used, 200 series and 400 series of a process is the 300 series of alternatives, but strictly speaking is not called the 400 series stainless steel, stainless iron, because it does not contain nickel element, so the magnet can attract. And the 200 series and the 300 series are nickel, so there is no magnetic and can't absorb iron.

304 is the most common variety in the 300 series, so the price trend of the whole stainless steel can be judged from the change of the price of 304. 200 series of nickel containing less nickel, 400 series no nickel, 300 series of nickel is the most, so the most affected by the nickel price is the 300 series.

The 300 can be simply divided into 304, 316, 321, 304L, 316L, 309S, 310S and so on, the distinction is based on the content of various metal elements in different properties of stainless steel with different content is not the same, the difference between 304 and 304L carbon (C) content is different, with L is that low carbon, also called low carbon, the difference between 316 and 316L is the same.
