202 Stainless Steel Pipe

202 stainless steel pipe is a kind of 200 series low-nickel and high-manganese stainless steel. The nickel content is the highest and the manganese content is about 8%. It is a nickel-saving stainless steel. The 202 steel pipe was developed to replace the 18-8 manganese-chromium-nickel austenitic stainless steel in the early stage.

202 Seamless Stainless Steel Pipe has moderate corrosion resistance and good resistance to most aggressive media. The mechanical properties of stainless steel pipe 202 grade are better than ordinary carbon steel, but slightly lower than other stainless steel materials. 202 grade pipe has excellent welding performance and can be welded by conventional welding methods.

202 stainless steel pipes are widely used in architectural decoration, municipal engineering, highway guardrails, hotel facilities, shopping malls, glass handrails, public facilities and other places.
