Not only that, its copper content is still low, and its manganese content is as high as seven, in a strictsense, it cannot be related to 304 at all.The industry believes that it may be more appropriate to define it as the D series. And D11 already exists, you may not be too muchto set a D7, D9. But you can't think of 18 chromes, you can get a 304 plus suffix, which is a bit too hot.You must know that 304 has a national standard and the name cannot be confused at will. I am especially worried about the idea ofsomeone who has been branded with this steel.2: Chemical Composition Tianjin Zhongyantiancheng Steel Co.,LtdCommodityStainless Steel PipeMaterial304DStandardGBJISASTM/ASMEDIN304DN/MN/MN/MChemical CompositionCMnPS≤0.14.0-8.0≤0.05≤0.005SiCrNNi≤1.0018-20≤0.32.0-3.53: Stainless Steel Seamless Pipe Or Welded Pipe Process4: Stainless Steel Seamless Or Welded Pipe Package5: Company Introduction
