SUS201 SUS202 Stainless steel coil surface smooth, with high plasticity, toughness and mechanical strength
200 series stainless steel is another name for Chromium-manganese austenitic stainless steel. This kind of material is developed on the basis of chrome-nickel austenitic stainless steel by adding manganese and/or nitrogen instead of precious metal nickel. The austenite elements in this material, in addition to manganese and nitrogen, generally there is an appropriate amount of nickel , manganese in steel plays a role in stabilizing austenite.
Usage: 200 series stainless steel can be formed by deep processing, can be widely used, combined with its corrosion resistance, mainly used in decoration, kitchen supplies, tableware, household appliances, food machinery, computer accessories, containers and other aspects.
| Chemical composition | ||||||||
| / | C | Si | Mn | Cr | N | P | S | Ni |
| 201 | ≤0.15 | ≤1.00 | 5.5~7.50 | 16.0~18.0 | ≤0.25 | ≤0.060 | ≤0.030 | 3.5-5.5 |

| Advantages | |
| ① | the biggest advantage of 200 series stainless steel is that it is cheaper than 300 series stainless steel. |
| ② | On the premise of weak corrosion, astm202 stainless steel can almost completely replace 304 stainless steel. |
| ③ | It is widely used in building decoration, tableware and kitchenware, sanitary equipment and appliances, household appliances, transportation and industrial equipment and components. |
| Disadvantages | |
| ① | compared with 304 ,200 series stainless steel, the corrosion resistance function is worse |
| ② | The machinability of 200 series stainless steel is far less than that of 304 stainless steel; |
| ③ | It is difficult to receive and take over the waste. If it is not clarified that it is 200 series waste, they will become a high-risk waste steel-concrete raw material, resulting in the manganese content of castings far exceeding the standard, and the unstable composition of the incoming charge of the steel plant; |
| ④ | 200 series stainless steel is non-magnetic, and its appearance is similar to 304. As a result, the "criminals and Philistines" are sold as "304", which brings great losses to users. |
| What are the surface processing techniques of stainless steel? | |
| 1 | Mirror surface processing |
| 2 | Sand blasting process |
| 3 | Drawing process |
| 4 | Plating color processing technology |
