202 stainless steel
202 stainless steel is one kind of 200 series stainless steel. The international stand is 1Cr18Mn8Ni5N. 202 stainless steel is widely used in building decoration, municipal works, guard bar, hotel application, shopping mall, flat bar with glass, some communal facilities.
202pipes are made by high precision automatic equipment, folded by melt itself and welding. Inflating air to protect the interior and exterior of pipe, do not need to feed by metal. The welding method is TIG, and process eddy current testing. The chemical composition of 202 stainless steel is following:
| Chemical composition/% | |||||||||||
| Grade | C | Si | Mn | P | S | Ni | Cr | Mo | Cu | N | other |
| 202 | ≤0.15 | ≤1.0 | ≤7.5~10.0 | ≤0.060 | ≤0.03 | 4.00~6.00 | 17.0~19.0 | —— | —— | ≤0.25 | |
