Simple classification of stainless steel
Stainless steel can be divided into 200 series, 300 series and 400 series, of which 300 series are the most commonly used.
304 is the most common variety in the 300 series, so the price change of 304 can generally determine the price trend of the whole stainless steel.
The 300 series can be divided into 304, 304L, 316, 316L, 321, 309S, 310S, etc. The basis for the distinction is the content of various metal elements, and the characteristics of stainless steel with different contents are different. The difference between 304 and 304L lies in The difference in carbon (C) content, the band L means that the carbon content is low, also called low carbon, and the difference between 316 and 316L is also the same.
