1. What stainless steel pipes are currently on the market and what are the differences in their quality?
At present, the stainless steel pipes sold in the market are mainly produced by stainless steel pipe manufacturers in two major regions, Foshan and Shandong. The stainless steel pipe materials are mainly 304, 201, 301 and so on. The difference is mainly due to the different contents of chromium and nickel. The material of 304 stainless steel pipe contains chromium 18 and nickel 8-9, while the material of 201 and 301 stainless steel pipes contains only chromium 14, 16 and nickel 1, 5 respectively. It has been scientifically demonstrated that the performance of stainless steel pipes with high chromium and nickel and good smelting technology is better, the corrosion resistance is stronger, and the finish durability is stronger.
