00Cr17Ni12Mo2 (316NG) steel is an austenitic stainless steel, which has good corrosion resistance and high temperature oxidation resistance. In comparison with conventional stainless steel, the addition of nitrogen to 316NG steel can significantly improve its corrosion resistance.
00Cr17Ni12Mo2 (316NG) is a highly alloyed stainless steel that contains 2-3% molybdenum, 17-19% chromium, 10-12% nickel and 0.08-0.15% nitrogen, and also other alloying elements such as manganese, silicon and sulfur. The nitrogen content of 316NG steel is usually between 0.08-0.15%. Nitrogen can improve the strength, ductility, weldability and stress corrosion resistance of 00Cr17Ni12Mo2 steel. Compared with the traditional stainless steel, 00Cr17Ni12Mo2 (316NG) steel has excellent corrosion resistance, especially in corrosive environments such as sea water and precipitation.
Due to its excellent corrosion resistance and high temperature oxidation resistance, 00Cr17Ni12Mo2 (316NG) stainless steel has been widely used in many industries. It is commonly used in chemical tanks and pipelines, pulp and paper industry, condensers, power plants, engines and corrosion resistant equipment. In addition, 316NG steel has good corrosion resistance to the elements of strong sulfuric acid, hydrochloric acid, organic acid and alkali.
In terms of mechanical properties, 00Cr17Ni12Mo2 (316NG) steel exhibits a combination of high strength and excellent resistance to intergranular corrosion. The nitrogen content of the steel can increase the strength of the steel, so that the tensile strength of 00Cr17Ni12Mo2 steel can reach more than 480 MPa. At the same time, 00Cr17Ni12Mo2 steel has excellent workability and weldability, which makes it a good choice for the production of components and pipes.
Although 00Cr17Ni12Mo2 (316NG) steel has excellent corrosion resistance, it is generally unsuitable for contact with caustic soda or other oxidizing agents. In addition, if the steel is used in a low-temperature environment, it should also be carefully inspected. In order to maintain the excellent corrosion resistance of 316NG steel, proper heat treatment is also necessary.
In conclusion, 00Cr17Ni12Mo2 (316NG) stainless steel is an austenitic stainless steel with excellent corrosion resistance, good workability and weldability. The addition of nitrogen to 316NG steel can significantly improve its corrosion resistance and make it more suitable for the components and pipes used in severe corrosive environments. However, because of its sensitivity to caustic soda, oxidation agent, and low temperature environment, 316NG steel must be carefully inspected before being applied. In addition, proper heat treatment is necessary for the steel to achieve its excellent corrosion resistance performance.
