Product Description
The addition of an appropriate amount of nitrogen to F51 stainless steel not only improves the pitting and SCC resistance of the steel, but also does not significantly reduce the plastic toughness due to the severe coarsening of the grains in the heat affected zone of the weld, and is also insensitive to welding hot cracks. Therefore, the corrosion resistance and mechanical properties of the heat affected zone of the weld are improved. The SCC resistance, wear corrosion resistance and corrosion fatigue resistance in many media are better than those of austenitic stainless steel [1-5]. In particular, the SCC resistance in a Cl-containing environment is particularly excellent [6]. The H2S SCC resistance is better than that of S30403 and S31603.
Plugs are often confused with relatively small pipe fittings. However, as an industrial tool, plugs are used in larger
infrastructure pipelines. Plugs provide a method of maintenance for drainage and sewage pipes as well as for the construction and testing of non-pressurized gravity pipelines without the need for trenching. Plugs primarily have three uses: these are to temporarily seal or stop the flow of fluids in pipes, leakage testing, and bypass flow. They are also used to block the ends of pipes during construction, maintenance, or repair to prevent dirt and other contaminants from entering.
