The chemical composition of austenitic stainless steel S30510 1Cr18Ni12 is as follows:
1Cr18Ni12 (304N) is an austenitic chromium-nickel stainless steel with a nominal composition of 18% chromium, 8% nickel and 0.12% nitrogen. The high nitrogen content significantly increases the corrosion resistance of the stainless steel, making it suitable for use in various high-temperature and corrosive environments and semi-conservative applications. Its higher surface-active elements, such as nitrogen, can reduce the risk of intergranular corrosion, chromium can enhance the ability of stainless steel to withstand stress corrosion cracking and pitting corrosion and nickel can improve the mechanical properties of stainless steel.
The chemical composition of this austenitic stainless steel is as follows:
Carbon (C) 0.03%
Manganese (Mn) 2.00%
Phosphorus (P) 0.045%
Sulfur (S) 0.03%
Chromium (Cr) 18.00%
Nickel (Ni) 8.00%
Nitrogen (N) 0.12%
Iron (Fe) Balance
The alloy also contains trace amounts of other elements, such as silicon, copper, aluminum and molybdenum.
1Cr18Ni12 (304N) stainless steel has good resistance to a wide range of atmospheric and chemical environments, with excellent general corrosion resistance and stress corrosion cracking resistance. Its corrosion resistance is superior to 304 stainless steel, but less than 316 stainless steel. It has excellent machinability and weldability and is non-magnetic. This steel is widely used in the manufacture of petrochemical equipment, medical and food processing equipment, chemical equipment and other industrial applications.
Due to its low carbon content and relatively high Ni content, 1Cr18Ni12 (304N) stainless steel has good intergranular corrosion resistance and stress corrosive cracking resistance. Its high temperature strength is also better than that of 304 stainless steel, but worse than that of 316 stainless steel. This steel is used for applications such as petroleum refining, chemical production, and food production, where corrosion resistance, but not high temperature strength, is required.
1Cr18Ni12 (304N) stainless steel has many advantages, including excellent corrosion resistance, non-magnetic properties and good formability, making it suitable for a wide range of applications. Its low carbon content makes the austenitic stainless steel more durable, making it ideal for applications that require long service life. In addition, its high nickel content makes this steel more expensive than other standard stainless steels. Because of its corrosion resistance, it is necessary to inspect it regularly to ensure it can withstand the harsh conditions.
