不銹鋼的簡易分類
Simple classification of stainless steel
不銹鋼可以粗淺的分為200系列,300系列和400系列三大類,其中300系列是最常用的,200系列和400系列一定程上是300系列的替代品,而嚴格來講400系列不叫不銹鋼,叫不銹鐵,因為里面不含鎳元素,所以用磁鐵可以吸引住。而200系列和300系列是有鎳的,所以是沒有磁性的,吸鐵吸不住。
Stainless steel can be roughly divided into three categories: 200 series, 300 series and 400 series. Among them, 300 series is the most commonly used one. 200 series and 400 series are substitutes of 300 series. Strictly speaking, 400 series is not called stainless steel, but stainless iron. Because it does not contain nickel, it can be attracted by magnets. The 200 series and 300 series have nickel, so they are not magnetic, and can not absorb iron.
304是300系列中最常見的品種,所以一般從304的價格變化可以判斷出整個不銹鋼的價格走勢。200系列含鎳少,400系列不含鎳,300系列含鎳最多,所以受鎳價影響最大的是300系列。
304 is the most common variety in 300 series, so the price trend of the whole stainless steel can be judged from the price change of 304. The 200 series contains less nickel, the 400 series does not contain nickel, and the 300 series contains the most nickel, so the 300 series is most affected by the nickel price.
300系列可以簡分為304、304L、316、316L、321、309S、310S等等,區分的依據是各種金屬元素的含量不同,含量不同的不銹鋼的特性也不相同,304和304L的區別在于碳(C)含量的不同,帶L的是表示含碳低,也叫低碳,316和316L的區別也是一樣。
300 series can be simply divided into 304, 304L, 316, 316L, 321, 309S, 310S and so on. The distinction is based on the different contents of various metal elements and the characteristics of stainless steel with different contents. The difference between 304 and 304L lies in the difference of carbon (c) content. The one with L indicates low carbon content, also known as low carbon, and the difference between 316 and 316L is the same
